What Is Diabetic Retinopathy?

Diabetic Retinopathy (DR) is one of the most prevalent eye diseases affecting the working age population. It is thought to be caused by high blood sugar levels which, over time, damage the tiny blood vessels of the retina at the back of the eye, making them swell and leak. Left untreated, DR can lead to vision loss and eventually blindness.

Since diabetic eye disease is typically painless and shows no symptoms until its advanced stages, it’s critical to get your annual eye evaluation, as an optometrist can detect the developing signs early enough to prevent vision loss.

Symptoms of Diabetic Retinopathy 

Diabetics may not realize they have diabetic retinopathy, because it develops silently. As the condition worsens, it may cause: 

• Blurred vision
• Poor night vision
• Colors to appear faded or washed out
• An increased presence of floaters
• Vision loss
• Blank or dark areas in your field of vision

Diabetic retinopathy symptoms usually affect both eyes.

Risk Factors

If you are diabetic, caring for your eyes by undergoing routine eye exams and taking care of your body by controlling blood sugar levels are critical to preventing vision loss. There are several risk factors associated with diabetic eye complications, including: 

• Poor blood sugar control
• Smoking
• High cholesterol 
• High blood pressure
• Pregnancy
• Excess weight/obesity

Are There Any Treatments for Diabetic Retinopathy?

Today’s treatment options may improve your vision, even if you feel your eyesight has begun to deteriorate. Medications can be injected to reduce swelling, and laser surgery can be used to shrink and seal off swollen and leaking blood vessels — preserving and, in many cases, even improving vision. 

While certain treatments may work, frequent monitoring of your eyes coupled with managing your blood sugar levels can go a long way toward preventing or reducing diabetic retinopathy complications. 

If You Have Diabetes, Make Sure to: 

• Control blood sugar and blood pressure to prevent long-term damage to the fine blood vessels within the retina.  
• Keep a healthy lifestyle routine, especially during stressful times such as the COVID-19 pandemic. (Plus, while diabetics are in the high-risk category, your chances of developing serious COVID-19 related complications is lower if your diabetes is under control.)
• Maintain a steady diet and exercise regimen to help the body and mind feel better. 
• Quit smoking, if applicable; you can reach out to a medical professional for guidance.
• Get yearly diabetic eye exams.

Preventing and managing diabetic retinopathy require a multi-disciplinary approach involving your eye doctor and other medical professionals. Your eye doctor will perform a comprehensive eye exam to determine whether you have diabetic retinopathy, assess its severity, and discuss preventative strategies as well as the latest treatment options.

Most people who wear glasses are familiar with the excitement and confidence boost that accompanies wearing new specs for the first time. But sometimes there is an adjustment period before your vision is fully comfortable. Things may look blurry, or you may notice feeling dizzy after prolonged wear. Some of these symptoms can be a normal part of the adjustment period, but sometimes they’re a reason to contact your eye doctor. If your new glasses are giving you trouble, speak with Dr. Kathleen Moore about ensuring that your eyesight is both clear and comfortable. 

When Will My Eyes Adjust to My New Glasses?

It can take a few days to a few weeks for your eyes and brain to fully adjust to your new eyewear, whether you are increasing your prescription or wearing eyeglasses for the first time.

Even if you are getting new glasses with the same prescription, different frames or lenses can alter your vision until you get used to the new frame style or lens type. The complexity of your prescription and whether you buy a lens with premium optics versus basic spherical lens or polycarbonate material all can affect the adjustment time. 

Progressive lenses tend to be the most difficult to adjust to. This is related to the peripheral soft focus zones, which are much less blurred for customized lenses prescribed by your local optometrist. 

What Are Some Possible Visual Symptoms I Could Experience?

Some common experiences shared by those adjusting to new eyewear include:

• Eye strain, headache
• Blurry vision
• Trouble with depth perception, nausea and dizziness
• “Barrel distortion” — objects appear distorted, for high plus lenses
• “Fishbowl effect” — the feeling that your visual field is being bent along the edges, as if you’re looking through a fishbowl, common in high minus prescriptions 

Why Do My New Glasses Give Me a Headache? 

Fatigued eye muscles can cause headaches. But your eyes aren’t the only things adjusting to your new lenses. Your brain is also working hard to create a clear picture of the messages it’s receiving from your eyes. This extra brain activity can sometimes bring on a headache, which should only last about a day or so. 

Why Do I Feel Dizzy With My New Glasses?

Dizziness and nausea can be caused by problems with depth perception, similar to motion sickness. With motion sickness, you feel uneasy because your brain is having difficulty understanding the position of your body in relation to the space surrounding it. So when you wear your new glasses, your brain may need some time to understand how to interpret the new images it’s receiving, causing you to feel disoriented or dizzy. 

When Should I Call My Eye Doctor?

When the adjustment period extends beyond a few weeks, there is a possibility that there was an error in the manufacturing of the lenses. Many people purchase eyewear from somewhere other than their eye doctor or order glasses online, and some studies have shown that up to 40% of online eyewear is made incorrectly or inaccurately. 

It’s important to note that many offices may charge fees to check eyewear that is not made by them and that there may be fees for rechecking a patient’s refraction when glasses are made by another source.

Discomfort that lasts longer than a couple of weeks means it’s time to call your optometrist. Persistent symptoms like headaches, dizziness, or blurry vision can indicate that your glasses aren’t well suited to your eyes and need adjusting. Your optometrist will double check the prescription of the glasses among other things to ensure that the new glasses are right for you. 

If you need new glasses or are having a hard time adjusting to a new pair, don’t hesitate to contact Centreville Eye Care Center to schedule an appointment with the Centreville eye doctor. 

Playing outside in a snowy winter wonderland can be magical. Under clear skies in the sunshine, the soft white landscape becomes just about irresistible, whether at home or travelling on a winter-weather get-away. 

Before you let your children run outside to build the most adorable snowman or fling themselves onto the ski slopes, make sure their eyes are well protected. Sun and snow can be a dangerous combination for both the eyes and skin. 

Sunlight Reflected in the Snow

We all know why we need to wear sunglasses and sunscreen in the summer. Winter, however, can be deceiving. It’s an illusion to assume that we are safe from sunburns during the colder season. 

Snow acts as a powerful mirror for sunlight and magnifies the effects of UV rays which would otherwise be absorbed by the ground. As a result, the eyes are exposed to both the UV radiation bouncing back from the snowy carpet and the rays shining down directly from the sun. 

If your family is skiing or snowboarding up in the mountains, you need to be even more careful! UV rays are more powerful at higher altitudes. Another important factor to remember is that ultraviolet radiation penetrates through clouds, so even if the sun is hidden behind them, it can still damage your eyes.

Can I Get Sunburned Eyes?

As you may have already guessed, yes —it is possible to get sunburned eyes. The condition is called snow blindness, or photokeratitis. Although most people do not actually experience permanent vision loss, photokeratitis is usually painful, causes extreme sensitivity to light, and can take up to two weeks to fully heal. 

A single day of playing outside in the snow and being exposed to intensive sun glare can be enough to cause snow blindness— though usually with a delay of several hours following sun exposure. What’s worse, if the eyes are repeatedly sunburned there is a risk of long-term damage. 

Symptoms of Snow Blindness

Just like a typical skin sunburn appears only after having been exposed to the sun’s rays, the same is true for the eyes. One sign of overexposure to UV is a stinging or burning sensation in the eyes, or a feeling of having sand in your eyes after a day spent in the snow. 

When eyes are sunburned, they become highly sensitive to light, making it difficult to be outside. Other symptoms include blurred vision, watery eyes, and swollen eyelids. In rare cases, photokeratitis can even cause temporary vision loss, but it doesn’t usually last longer than a day or two.

How Do I Protect My Eyes From Sunburn?

Prevent overexposure to sunlight by wearing sunglasses that absorb at least 95% of ultraviolet radiation when you go outside, no matter what time of year it is. An even more effective solution for winter activities is to strap on a pair of well-fitting UV protective sports eyewear, such as ski goggles. Wrap-around styles are ideal because they stay on even when you’re active, and block the sun’s rays from entering your eyes from the sides too. 

For winter sports lovers, there are plenty of good reasons to wear protective eyewear, and what works well in sports can be good for play as well. 

How Can I Treat Sunburned Eyes?

It’s after the fact, and you’re suffering from photokeratitis… now what? Give your eyes a rest. 

• Stay out of the sun for a few days until the symptoms die down. 
• You may find it comforting to wear sunglasses even when indoors. 
• For additional relief, place a cool, damp cloth over the closed eyelids while resting.
• Don’t wear contact lenses until the eyes return to normal. 
• Artificial tears can help keep the eyes moistened, soothe discomfort and promote healing. However, it’s important to consult an eye doctor before running to the pharmacy, since some eye drops are not well-suited for this condition. You can give us a call at 703-830-2020.

Now that you know the risks and precautions to take, you’re all set to enjoy the winter wonderland! Dr. Kathleen Moore at Centreville Eye Care Center is happy to help you protect yourself and your family from snow blindness, and offers expert treatment for sunburned eyes. 

Swimming in a pool with your contacts on or topping off your solution may seem harmless, but they could compromise your contact lenses and your vision.

Below are daily habits to adopt for optimal contact lens care:

Wash Your Hands Regularly

Whether you use daily or monthly contact lenses, make sure to first wash your hands. Placing your finger on some clear tape and seeing the mark you leave will give you some indication of what you’re putting on your contact lenses if you don’t wash and dry your hands beforehand. Avoid using scented or oily soaps, as their residue might stick to the lens surface. Similarly, avoid creams and lotions prior to inserting contacts into your eyes. 

This one simple and easy habit can make a massive difference in your eye health and can potentially prevent eye irritation and infections. 

Clean Your Contacts Daily

You must clean and disinfect your contact lenses on a daily basis, unless you use daily disposables, of course. There are several cleansing systems and solutions available — the choice depends on the type of lens you use. Speak with Dr. Kathleen Moore to determine the best cleaning solution for your lenses and eyes.

Avoid Contact with Water

It might seem harmless, but we advise against using tap water, as it contains impurities and microorganisms that can cause infections. Furthermore, tap water can lead your contacts to swell and change their shape. If you must swim with your contact lenses on, make sure to wear protective goggles and clean them with solution when you come out of the pool.

Never Ever Use Saliva 

Your mouth is filled with germs, which are fine for your teeth but not for your eyes. Avoid using saliva to “clean” or moisten your contact lenses.  

Do Not Top off Solution

Just as you shouldn’t mix spoiled food with fresh foods, you should not top off yesterday’s solution in your contact lens case with fresh solution. The concoction might not contain enough disinfectant to kill off organisms and clean your lenses. 

Routinely Change the Contact Lens Case

Many people don’t know about this one, but it’s recommended to change your contact lens case every 2-3 months, as microscopic dirt may linger in the case, leading to contamination and eye infections. 

Don’t Sleep with Your Lenses On

It’s important to give your cornea a chance to breathe; sleeping with your contacts may cause redness, soreness and infections. So make sure to remove your contact lenses before you get some shut-eye, unless they’re specialty lenses which are intended to be worn overnight. 

If you’re using orthokeratology (ortho-k) lenses to reshape your cornea, do wear them at night or as instructed by your eye doctor. 

Get That Annual Eye Exam

Don’t forget to book your yearly eye exam at Centreville Eye Care Center in Centreville, as your vision can change. You can’t purchase new contact lenses with an expired prescription anyway, so you’ll need an updated one when your contact lens supply is running low. Furthermore, getting an exam is also an excellent opportunity to ask Dr. Kathleen Moore any questions you may have.
