How to Deal with Contact Lens Discomfort

Do your eyes itch or burn when wearing contact lenses? There are several reasons why you may be experiencing contact lens discomfort. Discover the possible causes behind the problem and see what you can do to relieve your discomfort.

What Causes Contact Lens Discomfort?

Some of the top causes of uncomfortable contacts are:

Dry eyes

Dry eye syndrome is a common condition that arises when your tears can’t keep your eyes sufficiently lubricated due to an imbalance in the tear film. Certain diseases, medications and environmental factors, like high levels of dryness and wind, can cause or contribute to red, itchy or irritated eyes, especially when wearing contacts.

Allergies

Allergens are typically harmless substances that induce an allergic response in certain people. Pollen, mold, dust and pet dander are some of the most common airborne allergens that trigger eye allergies. Cosmetics and certain eye drops, such as artificial tears with preservatives, can also induce eye allergies, which can make contact lens wear uncomfortable.

Corneal irregularities

The cornea at the front of the eye may be irregularly shaped due to astigmatism, keratoconus, eye surgeries (i.e. LASIK or cataract surgery), eye injuries or burns, scarring, corneal ulcers and/or severe dry eye. Irregular corneas often prevent traditional contact lenses from fitting correctly and comfortably.

Symptoms of Contact Lens Discomfort

  • Burning, itchy, stinging eyes
  • Sensation of something being stuck is in the eye
  • Excessive watering or tearing of the eyes
  • Unusual eye secretions
  • Redness of the eyes
  • Reduced sharpness of vision
  • Blurred vision, rainbows, or halos around objects
  • Sensitivity to light

How to Relieve Contact Lens Discomfort

Try Different Contact Lenses

Nowadays, there are many types of contact lenses on the market, including specialty contacts for dry eyes and astigmatism. Meet with our optometrist for a personalized eye exam for contacts.

With the variety of contact lens brands available, switching to a different contact lens may be the simplest answer if you’re experiencing discomfort that isn’t connected to improper fitting or issues with tear production. If your existing lenses fit well but still irritate and dry out your eyes, speak to us about trying a different design or brand of contact lenses, or changing your lens-wearing schedule.

Artificial Tears or Eye Drops

Over-the-counter artificial tears or eye drops are a common way to temporarily relieve contact lens discomfort. However, it’s important to keep in mind that unless prescribed by an eye doctor, they may not be treating the root of the problem.

Moreover, certain eye drops are incompatible with contact lenses, and may damage your contacts or harm your eyes. We also recommend staying away from products that claim to remove redness from your eyes, which temporarily reduce the size of blood vessels to lessen redness, but do not address the underlying cause of the condition, and can actually worsen it over time.

Take Good Care of Your Lenses

Inadequate contact lens care leaves residue on your lenses, which can discomfort, harmful eye infections and inflammation. Below are a few important contact lens hygiene guidelines to follow:

  • Before handling your contact lenses, thoroughly wash and dry your hands.
  • Remove your lenses before showering, bathing or swimming to prevent infection.
  • Do not sleep in your contact lenses (unless they are approved for sleeping).
  • Replace your contact lenses according to the manufacturer’s instructions (e.g., don’t reuse daily wear lenses).
  • Regularly clean your contact lens case and ask your eye doctor when to replace it.
  • Only use a contact lens solution that is appropriate for your lenses.
  • Never reuse or mix contact lens solutions.
  • Schedule regular appointments with your eye doctor.

Q&A

What kinds of contacts are available?

Contact lenses are available in a wide range of materials and replacement schedules. Disposable contact lenses and extended wear contacts are the most convenient for many users.

I’ve already been fitted for contact lenses, so why did my optometrist ask me to come back?

If you’re asked to return a week later, it’s because your optometrist wants to rule out any issues, such as contact lens-related dry eye or irritation.

If it’s been around a year since your last eye checkup, you’ve likely been contacted to check whether your prescription has changed and to evaluate your eye health. The sooner problems are detected and treated, the better the outcome.

6 Ways To Maintain Eye Health If You’re Over 50

Aging and certain lifestyle choices can affect your vision, especially if you’re in your 50’s and up. While it’s normal for your eyes and vision to change, there are certain actions you can take to protect your sight.

6 Tips for 50+ Eye Health

  1. Eat Well

    A well-balanced diet helps maintain a healthy body including healthy eyes, and reduces your odds of developing some very serious eye diseases. Nutrients and nutritious foods, which help prevent vision loss include:

    • Vitamin A: Carrots, spinach, kale, egg yolks, dairy products
    • Vitamin C: Citrus fruits and juices, broccoli, potatoes, green peppers
    • Vitamin E: Whole grains, eggs, sunflower seeds, vegetable oils
    • Fatty Acids: Coldwater fish, such as mackerel, rainbow trout and salmon; corn oil, sunflower oil
    • Lutein: Kale, spinach, broccoli, brussels sprouts, corn
    • Zinc: Poultry, meat, fish, dairy products, whole grains
  1. Quit Smoking

Smoking can significantly increase the chances of developing age-related macular degeneration and cataracts, as well as diabetic retinopathy in diabetics. So if you’re a smoker, the sooner you quit, the better.

  1. Exercise

Exercising for at least 20 minutes a day is great for your whole body, including your eyes, by increasing blood flow to the optic nerve and retina! It isn’t necessary to engage in strenuous exercise—in fact, a brisk walk will suffice.

  1. Protect Your Eyes

Sunglasses

Protecting your eyes from ultraviolet rays with UV-blocking sunglasses can slow down the development of cataracts, prevent sun damage to your retina, and lower the risk of skin cancer near your eyes.

Protective eyewear

Another way to protect your eyes is to wear protective eyewear. If you play sports or work with materials such as wood, glass or metal, protective eyewear can shield your eyes from splinters and shards, as well as fast-moving objects like balls and hockey pucks.

  1. Give Your Eyes a Rest

If you spend a lot of time reading, driving or looking at digital devices, you may develop eye strain and eye fatigue. By implementing the 20-20-20 rule, especially during prolonged computer or smartphone use, you can give your eyes some much-needed rest. All you need to do is this: every 20 minutes look at something 20 feet away for at least 20 seconds.

  1. Have Regular Eye Exams

And finally, a comprehensive eye exam is crucial, as it can detect eye conditions that don’t display any symptoms until vision loss has already occurred.

These conditions include:

When detected early, treatment can often prevent permanent vision loss or even blindness. Less serious and more common, presbyopia or age-related farsightedness, develops with age, and simply updating your prescription for glasses or contact lenses at your routine eye checkup can keep you enjoying the arm’s-length activities you love.

Age-related vision changes can be challenging, both emotionally and physically. However, some of these can be mitigated by implementing the tips above. Schedule an eye exam with Dr.'s Eyecare Center in Burlington to check your eye health today!

Q&A

How does aging affect your eyes?

Aging causes changes in every part of your body, including your eyes. As you age, the lens inside your eye begins to harden, which leads to presbyopia (age-related farsightedness). This makes it more difficult for your eyes to focus on near objects and tasks like reading. Other common age-related eye problems include:

  • Age-Related Macular Degeneration
  • Cataracts
  • Glaucoma
  • Diabetic Retinopathy
  • Dry Eyes
  • Floaters
  • Changes to Peripheral Vision

Can I do anything about my chances of vision loss?

It is estimated that half of all visual impairment and blindness can be prevented through early diagnosis and treatment. So make sure you get regular eye exams to ensure that all is in check.

 

Why Eye Exams Are More Important Than Ever

Why Are Eye Exams near you in Burlington, New Jersey Important?

Since the onset of COVID-19, many children have been learning remotely through distance learning programs. While parents are concerned about their children falling behind academically, eye doctors are concerned that undiagnosed vision problems may impact the child’s school performance.

Undetected vision problems may hinder a child’s ability to learn. That’s why eye doctors strongly recommend that children undergo a thorough Eye Exam before the new school year begins.

While it’s tempting to rely on vision screenings provided by schools, these superficial visual acuity tests can identify only a limited number of vision problems. Only a comprehensive Eye Exam conducted by an eye doctor can accurately diagnose and address a wide range of problems related to vision and eye health.

How Is Vision Affected By Online Learning?

The amount of time children spend looking at digital screens was already a concern in the pre-pandemic era—but the covid pandemic has only exacerbated the issue. According to the Indian Journal of Ophthalmology, children spent twice as much time on screens during COVID-related closures than they did prior to the pandemic.

For one thing, spending prolonged periods of time on digital screens forces the eyes to work harder, making children and adults more susceptible to digital eye strain, one of the hallmark symptoms of computer vision syndrome. People who spend 2 or more consecutive hours staring at a screen are at higher risk of developing this condition.

Some digital eye strain symptoms include:

  • Blurred vision
  • Dry eyes
  • Eye fatigue
  • Eye pain
  • Headaches
  • Neck and shoulder pain

These symptoms can be caused by a combination of the following factors:

  • Glare and reflections from the screen
  • Excessive time looking at a screen
  • Poor lighting
  • Poor posture
  • Screen brightness
  • Undetected vision problems

In addition to digital eye strain, several studies have found that children who spend many hours indoors doing “near work” — writing, reading and looking at computers and other digital devices — have a higher rate of myopia progression.

A study published in the American Academy of Ophthalmology’s professional journal, Ophthalmology, found that first-graders who spent at least 11 hours per week playing outside in the sunshine experienced slower myopia progression. Some researchers theorize that exposure to sunlight and looking at distant objects while playing outdoors might help prevent myopia progression.

Why Are Eye Exams Important?

Up to 80% of a child’s learning is visual, so even the slightest vision problem can have a negative impact on their academic achievement. Taking a child in for an Eye Exam once a year will allow your eye doctor to detect and correct refractive errors like myopia (nearsightedness), hyperopia (farsightedness) and astigmatism, and check their visual skills, such as convergence insufficiency, binocular vision, focusing and more.

Comprehensive eye exams are the best way to detect mild and serious eye health conditions. Eye exams are especially important for children with a family history of eye health problems.

While regular eye exams are essential for every member of the family, they’re especially for those who spend a good portion of their day in front of a screen.

At what age should a child have an Eye Exam

According to the American and Canadian Optometric Associations, it’s recommended for a child to have their first Eye Exam between 6-12 months of age.
Before a child starts school, they should undergo an Eye Exam, and every one to two years after that, based on their Eye Doctor’s recommendation.

Does my child need an Eye Exam if they passed the school vision screening?

Yes! School vision screenings are superficial eye evaluations designed to diagnose a limited number of vision problems like myopia. They do not check for visual skills and other problems that may hinder your child’s academic success.
Your Eye Doctor will evaluate your child’s vision and eye health, along with visual abilities, including depth perception and eye tracking, to let you know whether your child’s eyes are “school-ready.”

Why Are Blue Eyes More Sensitive To Light?

Why Do Your Eyes Need Sun Protection?

Eyes of all colors need shielding from the sun’s harmful ultraviolet (UV) rays. Exposure to UV light can contribute to the formation of short-term and long-term eye conditions such as corneal sunburn and macular degeneration.

That’s why it’s so important to choose high-quality Sunwear with 100% UV blocking lenses and to throw on a sun hat for an added layer of protection.

UV protection is important for individuals of all ages—especially children—who are more susceptible than adults to the sun’s harmful rays and tend to spend more time outdoors. It is estimated that up to 80% of a person’s lifetime exposure to UV rays happens before the age of 18.

Why are Blue Eyes More Sensitive to Light?

Lighter-colored eyes like blue, hazel, and green have less of a pigment called ‘melanin’ than brown eyes do.

Melanin helps protect the retina from UV damage and blue light, putting those with blue eyes at a higher risk of developing UV-related eye damage.

If you have blue eyes, you may have experienced this first-hand. Bright light may be uncomfortable or you may want to reach for your shades as soon as you leave the house on a sunny day.

That’s why optometrists urge blue-eyed patients to be particularly vigilant about UV protection, so as to mitigate their chances of developing eye disease and other complications.

How We Can Help

Whether you have blue eyes or not, sunglasses are an important part of keeping your eyes healthy for a lifetime.

At Dr.’s Eyecare Center, we’ll be happy to advise on the perfect high-quality and protective pair of sunglasses to suit your needs and personal style.

Should I wear sunglasses even when it’s not sunny outside?

Yes! You should wear your sunglasses whenever outdoors during the day, even on an overcast, winter day. UV light can pass through clouds and reflect off surfaces like car windows and pavement.

What type of sunglasses are the most suitable for blue eyes?

The most protective sunglasses are wraparound sunglasses that protect the eyes from every angle. You can also opt for photochromic lenses, which offer total UV protection but only become tinted when exposed to outdoor sunlight, and turn clear when you come indoors again. Your optometrist can help you choose the best lens and frame options for your needs and lifestyle.

Why Are Dilated Eye Exams So Important?

Dr.’s Eyecare Center Dilated Eye Exam near you in Burlington, New Jersey

Having your eyes dilated during an eye exam may seem like a nuisance. But when you consider the benefits of a dilated eye exam, the temporary blurred vision and sensitivity to light that typically follow are definitely worth it.

What Are Dilated Eye Exams?

At some point during a comprehensive eye exam, your optometrist will shine a bright light into your eyes to examine the back of your eye, called the retina. The problem is that bright light causes the size of the pupil’s opening to shrink, which makes it hard for the optometrist to see a large portion of the retina.

That’s why eye doctors apply special eye drops in each eye to keep the pupils open. A dilated pupil allows for a much more accurate assessment of your eye’s structures, including the focusing lens, blood vessels and tissues at the back of the eye called the retina, as well as the optic nerve and macula.

Dilating the eyes makes it easier for your optometrist to detect the following conditions and diseases:

It’s important to note that many of these conditions can develop without noticeable symptoms, until they cause vision loss at which point treatment may be more challenging, making dilated eye exams all the more crucial.

The Dilation Process

First, your eye doctor will apply eye drops to each eye to trigger dilation of the pupil. Your eyes should be fully dilated about 10-20 minutes later.

Your eyes will remain dilated for 4-6 hours, and during this time you may be sensitive to light. That’s because the larger pupil allows more light than usual to enter the eye. Many patients find it more comfortable to wear sunglasses until their eyes return to normal.

Reading and using a computer may be difficult with dilated eyes, and your vision may be blurred. Some patients report feeling a tightening sensation in their eyelids, or headaches.

Dilated eye exams are a crucial part of keeping your eyes healthy. To schedule your comprehensive eye exam, call our optometry practice today!

At what age should one have a dilated eye exam?

You should have your dilated eye exam no matter your age. Most eye doctors will dilate a new patient at their first exam regardless of age to get a baseline of their retinal health.

Will I be able to return to work after a dilated eye exam?

Everyone reacts differently, so it’s hard to tell. If your job requires you to focus on small print or detail, it may be challenging. Typing and writing may also be difficult with dilated pupils. To be on the safe side, book your appointment at the end of your work day, clear your schedule after your eye exam and only plan to do activities which aren’t visually demanding.

Why Does Bono Always Wear His Signature Shades?

Ask our optometrist in Burlington how Do Sunglasses Help People With Glaucoma?

Ever wonder why rock superstar Bono wears sunglasses, even when indoors? It’s not due to his “look”, but rather is related to managing his glaucoma.

Ever wonder why Bono always wears shades, even when indoors? U2’s frontman doesn’t wear sunglasses simply as part of his image. Bono has had glaucoma, a build-up of pressure in the eyeball, which can damage the optic nerve and potentially lead to blindness if untreated—for over two decades now.

The real reason he wears his trademark shades is due to this progressive, sight-robbing eye disease, to protect his sensitive eyes from light and glare.

How Do Sunglasses Help People With Glaucoma?

People with glaucoma experience sensitivity to light (or photophobia) and glare, among other symptoms. When the sun is strong, those with this condition will be more affected by glare emanating from a variety of surfaces, like water, snow, sand or pavement, than the average person. Furthermore, certain glaucoma medications constrict the pupils, which can further contribute to acute sensitivity to glare and light, as well as redness and irritation.

That’s why people with glaucoma — and lots of people without glaucoma — feel best wearing sunglasses when outdoors on a sunny day, in a bright indoor space, or while driving in the early evening.

Here’s How You Can Protect Your Eyes

By wearing sunglasses that offer 100% UV protection, you can reduce your risk of developing sight robbing diseases, like cataracts and macular degeneration, and reduce glaucoma symptoms. Polarized lenses, in particular, can help with glare. With yearly comprehensive eye exams, early diagnosis and consistent treatment, you can prevent vision deterioration from glaucoma or similar sight-threatening eye diseases.

Can glaucoma be cured?

While there is currently no cure for glaucoma, there are many effective treatment options available. Treatments that can help stop or slow the progression of glaucoma include eye drops, oral medications, as well as laser and surgical procedures.

How can glaucoma vision loss be prevented?

The best way to avoid glaucoma-related eyesight deterioration is to undergo regular eye exams, as glaucoma can be detected and treated even in its early stages, which can prevent significant vision loss or blindness. That’s why routine eye exams that include glaucoma testing are so important.

Why Do We Need Glasses?

The most well-known part of a comprehensive eye exam is the basic vision test. When you have a general vision test, one of the main conditions the eye care practitioner is checking for is a refractive error. A refractive error means there is an abnormality in the shape of the eye, changing the eye’s ability to focus light directly onto the retina.This causes blurred vision and can usually be corrected by wearing prescription eyeglasses, contact lenses and possibly, alternate treatments such as vision therapy, ortho-k, LASIK or refractive surgery such as LASIK.

 

The term, “refractive error” refers to a problem with the process of refraction that is responsible for sight. Normally, light rays that enter your eye are refracted or bent through the cornea and the lens, and ultimately converge or are focused onto a single point on the retina. From the retina, messages are sent through the optic nerve to the brain which then interprets these signals into the image that we are seeing.   

 

In order for this process to work effectively, the anatomy of the eye including the length of the eye and the curvature of the cornea and the lens must be just right to be able to focus the light onto the retina. When this is not the case, a refractive error will occur.

 

There are several different types of refractive errors, depending on which part of the eye is affected, and it is possible to have multiple refractive errors at the same time:  

 

Myopia or nearsightedness:

In myopia the length of the eyeball is too long which results in light coming to a focus in front of the retina, rather than on the retina. This allows the individual to see well when objects are close but not clearly when looking at objects at a distance.

 

Hyperopia or farsightedness:

Hyperopia is when the eyeball is shorter than normal and can result in near objects being blurry. However, people experience hyperopia differently. Sometimes distant objects are clear while other times people may experience overall blurred vision near and far or no problems at all. In children particularly, the lens may accommodate for the error allowing for clear vision but may cause fatigue and sometimes crossed eyes or strabismus. Hyperopia causes eyestrain or fatigue especially when looking at near objects for a period of time. Often people with 20/20 vision may still need glasses at their desk to relax their eyes and improve concentration.

 

Astigmatism:

Astigmatism is usually the result of an irregularly shaped cornea (although it can sometimes also be due to a misshapen lens). The cornea, which is normally round, is more football-shaped in an eye with astigmatism, resulting in multiple focus points either in front of the retina or behind it (or both). People with astigmatism usually have blurred or distorted vision to some degree at all distances, near and far.

 

Presbyopia:

Presbyopia is an age-related condition which usually begins to appear sometime after 40.  As the eye begins to age, the lens stiffens and can no longer focus clearly on objects that are close.  

 

It’s important to note that presbyopia is often confused with hyperopia, as both cause problems focusing at near distances.  However, high hyperopia can also cause blur at far distances as well, especially in dim lighting, and depth perception problems can result in motor vehicle accidents.  In these instances people with hyperopia could use glasses at any distance.

If you are having trouble seeing, it is important to have an eye exam to determine the cause of the problem and to effectively correct your vision. Even if your vision is fine, you should schedule a routine eye exam on a regular basis to ensure that your eyes are healthy and that any potential problems are caught early.

 

Eye Safe Toys and Gifts for This Holiday Season

‘Tis the season for giving, and parents, grandparents, family and friends need to know which toys and games to leave off the list because they can pose a risk to children’s health and eyesight. Last year nearly 252,000 emergency visits were due to toy-related injuries, almost half of which were to the head or face. Further, about 1 in 10 children’s eye injuries treated in the emergency room can be traced back to toys, most of which occur in children under 15 years of age.

The most common types of eye injuries that occur from toys can be anything from a scratch on the cornea (the front surface of the eye) to very serious injuries that can threaten vision such as traumatic cataracts, corneal ulcers, bleeding inside the eye and retinal detachment.

Most of these injuries can be prevented by taking the proper measures to evaluate the safety of gifts before they are purchased and to supervise children during any play with toys that could have the potential to cause damage or harm.

Here are some tips on how to select safe toys for children this holiday season:

  1. Check age recommendations on all toys to make sure they are age appropriate and suitable for the child’s maturity level. If younger siblings are present, ensure that any toys made for older children are kept out of reach.
  2. When possible, check toys for a seal of approval that the product meets national safety standards from a toy safety testing organization such as the American Society for Testing and Materials (ASTM) or the Canadian Toy Testing Council.
  3. Do not purchase toys that have a projectile or sharp, protruding parts. Toys such as darts, guns, arrows or sharp propelling toys can cause serious eye injuries that can lead to permanent eye damage and even vision loss. Even high-powered water guns such as super soakers or soft foam dart guns can cause significant damage when shot at close range.
  4. Purchase safety eyewear with polycarbonate lenses to accompany sports equipment, chemistry sets or woodworking tools. Speak to your optometrist to learn more about the best option for your child’s hobby of choice.
  5. Check that toys with sticks or handles such as swords, fishing rods, pogo sticks, brooms or pony sticks have rounded edges or handles and avoid or supervise use with little children.
  6. Any toys or devices that have a laser or bright light (such as laser pointers or flashlights which are sometimes used by kids to play laser tag) can be dangerous. Bright lights such as those produced by high-powered flashlights can cause temporary vision loss that can lead to a risk of a fall or accident. Further, laser pointers are not safe for use by children as the light intensity can cause permanent vision loss if shined in someone’s eyes.

When purchasing a toy for a child that is important to you, make sure you are considering what is most important – their safety. Ask us if you have any questions about the eye safety of a toy or gift you are considering.

How Do We See?

Have you ever thought about how vision works? Seeing is an incredible gift made possible by a system in which the eye and the brain process visual information from the outside world. If any step of that process does not function properly, vision will be impaired.

Similar to a camera, the eye transmits light from the world around us into an image that we can perceive. Certain parts of the eye even function like the different parts of a camera such as the shutter, the lens and film (if we can hearken back to the days when we used film in cameras). Here is a quick breakdown of the fascinating way our eyes and brain enable us to see and experience the world around us:

The Vision Process

Light reflected from an object in our field of view is gathered by the cornea which is essentially the clear “window” to our eye. The cornea then refracts the light rays through the pupil (the center of the iris where light enters the eye). The iris, which like the shutter of a camera will enlarge and shrink based on how much light is coming in, then passes the image onto the crystalline lens. Just like a camera lens, the lens in the eye focuses the light rays, projecting them to a point at the back of the eye called the retina, where the image will appear upside down. The retina contains a thin layer of color-sensitive cells called rods and cones that perceive color.

From the retina, the visual signals travel to the brain via the optic nerve. The brain receives information from both eyes and must then converge the images (and flip them right side up) to get a complete picture.

Vision Problems

A breakdown in vision can happen at any point in this process. From the muscles that control the eyes, to the parts within the eye, to the pathway to the brain. Sometimes vision impairment is due to technical problems with the eye receiving the information and passing the signal on, such as convergence insufficiency (inability to coordinate the eyes to converge on one point), myopia (nearsightedness) or cataracts (clouding of the lens).

Other times, the eyes might work perfectly, but there is a problem with the brain interpreting the signals it receives. In these cases we can’t “see” in the traditional sense, because our brains aren’t able to properly “read’ the signals or we don’t know what we are looking at. This is the case for some learning disorders that are caused by the visual processes in the brain such as dyslexia.

As you can see, vision is quite a complicated process. A simple vision exam isn’t always able to determine vision problems, especially in children which is why it is so important to have regular comprehensive eye exams, to measure the health of the eye and all of its parts.

How to Prevent Diabetic Vision Loss

Eye Complications of Diabetes

It’s true. Diabetics have a higher risk of blindness than those without the disease. That fact coupled with the superior prognosis of early intervention, makes it easy to understand why optometrists and doctors say routine eye care is absolutely essential. Below, we’ll discuss what your eye doctor is looking for during a diabetic eye exam.  

As the incidence of diabetes increases, it is important to spread awareness about the risks and proper preventative care for diabetes patients. November is Diabetes Awareness month, so read on!

Diabetics are at greater risk of for a number of eye problems.  

Diabetic Retinopathy:

Diabetic retinopathy is the term used for the disorders associated with diabetes that cause progressive damage to the retina.  The longer a patient has had diabetes, the more likely it is that he will develop these conditions which can be very serious, vision-threatening complications. 

There are two types of retinopathy: nonproliferative and proliferative. 

Nonproliferative retinopathy, which is the most common form, is when capillaries at the back of the eye become weakened and may start to leak blood and fluids. Nonproliferative retinopathy, which often has no symptoms, can be characterized as mild, moderate or severe, depending on how many blood vessels are affected and becoming blocked. This type of retinopathy usually doesn’t require treatment and doesn’t cause vision loss, unless the leaking fluid ends up in the macula where the eye focuses – a condition called macular edema. If this happens, vision can be blurred and even lost so preventative treatment is essential.  

Proliferative retinopathy is much more severe. This is when so much damage is done to the blood vessels that they begin to close off. New blood vessels begin to grow in the retina as a response to this deterioration. The new and weak vessels can leak blood, impairing vision, or can form scar tissue which can distort the retina or cause a retinal detachment.

Proliferative retinopathy requires urgent referral to an ophthalmologist for treatment. While it usually takes years to develop, some instances of proliferative retinopathy can occur within weeks or months if blood sugars are not well-controlled. Pregnancy can also accelerate proliferative retinopathy in known diabetics. Yet if detected early, treatment can be done successfully. 

Like high blood pressure, there are often no warning symptoms until advanced stages of diabetes. It is best to get checked each year by an optometrist. If you experience any changes in your vision such as spots in vision, flashes of light, blurred or double vision (rarely pain), make an appointment with your eye doctor immediately. Treatments do exists for retinopathy and many of them are successful in repairing damage and sometimes even restoring vision.

Cataracts: 

Cataracts are a clouding of the lens of the eye which blocks light from entering and impairs vision. While cataracts are a fairly common and treatable condition, people with diabetes are 60% more likely to develop the condition and often get them at a younger age. Those with the condition also may experience vision fluctuation which occurs from sugar levels affecting the lens of the eye. Cataracts often progress faster in diabetics as well. In serious cases of cataracts, a surgical procedure is done to remove the natural lens of the eye which can sometimes cause complications in diabetic patients that may already have symptoms of other conditions such as diabetic retinopathy.

Glaucoma:

Glaucoma is a serious condition where pressure builds up in the eye causing damage to the retina and optic nerve and eventually if left untreated, blindness.  Diabetics are 40% more likely to develop glaucoma and the risk increases with age and the amount of time the individual has had diabetes. There are treatments for glaucoma including medications and surgery but early detection and treatment are essential to prevent permanent vision loss. Glaucoma is often called the “silent thief of sight” because vision loss often doesn’t occur until significant damage is done. Therefore, yearly eye exams are essential. 

Cornea Alterations:

Diabetics may experience reduced sensitivity in their cornea. This means that contact lens wearers that are diabetics should be more cautious, as they develop higher tolerance if the lens irritates the eyes and may be at greater risk of infection. 

Eye Muscle Disturbance:

More advanced diabetes cases can show restriction of eye muscle movement due to nerve palsy. 

 

For diabetics, the key to early detection and treatment – and therefore preserving your vision – is to have your eye health monitored on a regular basis. Get your eyes examined every year by an optometrist and if you experience any changes in your vision such as spots, floaters, blurred vision or pain, make an appointment with your eye doctor immediately.
