Computer Vision Syndrome?
How to minimize the impact of increased hours spent in front of the screen.
With COVID-19 causing stay-at-home recommendations and virtual meetings, people are in front of a screen now more than ever. Computer vision syndrome is a group of vision and eye-related problems that come from extended periods of screen time—be it on a computer, cell phone, or other digital devices.
Nearly 60% of Americans use digital devices for five or more hours each day and 70% of Americans use two or more devices at a time. 65% of Americans report experiencing symptoms of digital eye strain.1
Viewing a computer screen is not the same as reading a printed page. Computer letters are often not as clear as the written word, and glare can be a problem as well. Viewing distances and angles are different than holding a book, creating a different demand on the eyes. Eyeglasses, particularly bifocals, may not be suited for the angle or distance to the computer screen, adding to eye strain. Additionally, uncorrected or undercorrected vision problems can become worse when viewing screens. According to the American Optometric Association, those at greatest risk of developing computer vision syndrome are those who spend two or more continuous hours on the computer per day.
Symptoms of computer vision syndrome include:
- Headaches
- Blurred vision
- Dry eyes
- Neck and shoulder pain
For a majority of individuals these symptoms are temporary and will go away when computer work has stopped. Those individuals who are experiencing lingering symptoms should see an eye care professional for help. A comprehensive eye exam can be utilized to help diagnose computer vison syndrome. 90% of patients do not talk with their eye care provider about computer vision syndrome symptoms.
Recommendations to minimize the impact of hours in front of a screen include:
- Maximize lighting and minimize screen glare
- Place your screen at the most efficient distance and level for eye comfort - Most people find it more comfortable to view a computer screen when their eyes are looking downward.
- Make sure your chair and desk are at a comfortable level – Adjust the height of your chair so that your feet are flat on the floor or on a footrest so that your thighs are parallel to the floor.
- Adjust your computer display settings—brightness, color, and text size
- Keep key objects — such as your telephone or printed materials — above the keyboard and below the monitor
- Blink often
- See your eye care specialist to ensure vision is corrected as needed
- Consider blue light filtering glasses
Follow the 20-20-20 rule: Every 20 minutes look at least 20 feet away for 20 seconds.
Treatment Options
Treatment for some individuals will include prescription eyeglasses. These individuals may not require glasses for activities of daily living but will benefit from glasses that are specialized for computer screens. If you don’t require corrective lenses, some blue light coatings can be applied to non-prescription eyewear. Your eye care provider will be able to recommend the best course of treatment.

But if you imagine losing your
sight, it's devastating.
Diabetes is the leading cause of vision loss in people 18-64 years old. And there are often no obvious signs or symptoms.
But the great news is an annual routine eye exam could prevent 95% of vision loss caused by diabetes.

Step 01
Know Your Risk for Diabetes
Many people have prediabetes or diabetes for years without knowing it because early symptoms can be so easy to miss. That’s why an annual comprehensive eye exam is critical for prevention and early detection of diabetes-related eye complications. Diabetes affects the tiny blood vessels in the back of your eye, which your eye doctor can examine during an eye exam—often times long before you ever even experience other symptoms.
Wondering if you’re at risk for type 2 diabetes? We’re here to help. Take our free, 60-second online risk test—and if you are at risk for diabetes, talk to your health care team about getting tested.
Step 02
Know the Warning Signs of Diabetic Eye Disease
Some diabetic eye diseases have no signs or symptoms until they are too obvious to ignore, which might present as:
- Blurred vision
- Dark spots or "holes"
- Flashes of light
- Seeing an increased amount of floaters
- Poor night vision
This is why regular comprehensive eye exams are so important—to help avoid vision loss and potentially catch these conditions early.
Step 03
Take Control of Your Eye Health
Routine eye exams can help identify problems that when treated can prevent or delay vision loss due to diabetic eye complications in many people with diabetes. Unfortunately, many people with diabetes don't get their eyes examined regularly and are diagnosed too late.
Schedule an annual comprehensive eye exam with your eye doctor at least once a year so they can detect any problems early and treat them.
And be sure to follow the other steps for healthy eyes, as well.
Diabetic Eye Diseases
Some diabetic eye diseases have no obvious symptoms–but the damage done by high blood glucose levels can be caught early during a routine eye exam.
Diabetic Retinopathy
High blood sugar levels can cause damage to blood vessels in a part of your eye called the retina. There are various stages of diabetic eye disease. Diabetic Retinopathy is the most common and serious type of eye problem associated with diabetes.
Symptoms
Often none. Also common: blurred vision, distorted vision, impaired colors, seeing spots, or vision loss
Treatment
Good diabetes management including controlled blood glucose levels. Other treatment may include medication via injections or eyedrops, laser treatment, or surgery.
How to catch early
Annual dilated eye exam
Diabetic Macular Edema
Diabetic Macular Edema is when the tiny blood vessels in the retina leak fluid which builds up and causing swelling. This distorts vision and may lead to permanent vision loss.
Symptoms
Blurry, distorted, or wavy central vision. Color perception may also appear washed out.
Treatment
Good diabetes management including controlled blood glucose levels. Other treatment may include medication via injections or eyedrops, laser treatment, or surgery.
How to catch early
Annual dilated eye exam
Glaucoma
Glaucoma is an eye disease that causes damage to your optic nerve resulting in irreversible vision loss and is more common in people with diabetes.
Symptoms
Often none. Sometimes headaches, eye pain, blurred vision, watery/red eyes, halos, vision loss
Treatment
Good diabetes management including controlled blood glucose levels. Other treatment may include medication via injections or eyedrops, laser treatment, or surgery.
How to catch early
Annual dilated eye exam
Cataracts
Usually associated with age, cataracts are more common and occur earlier in people diagnosed with diabetes. With cataracts, the lens in your eye becomes cloudy due to the breakdown of proteins in the lens.
Symptoms
Blurred vision, hazy vision, halos around lights particularly at night
Treatment
Cataract surgery to replace the lens near the surface of the eye.
How to catch early
Annual dilated eye exam
Know Your Risk for Diabetes
Before people develop type 2 diabetes, they almost always have prediabetes—blood sugar levels that are higher than normal but not yet high enough to be diagnosed as diabetes. There are often no clear symptoms of prediabetes so you may have it and not know it. In fact, many people have prediabetes or diabetes for years without knowing it because early symptoms can be so easy to miss. That’s why an annual comprehensive eye exam is critical for the early detection and prevention of diabetes-related eye complications. Diabetes affects the tiny blood vessels in the back of your eye, which your eye doctor can examine during an eye exam—often times these exams detect problems before you ever even experience other symptoms.

Take Control of Your Eye Health
Routine eye exams can identify problems that when treated can prevent or delay vision loss in many people with diabetes. Unfortunately many people with diabetes don’t get their eyes examined regularly and are diagnosed too late. Be sure to schedule a comprehensive eye exam every year.
Schedule appointments with your eye doctor at least once a year so they can detect any problems early and treat them.
And be sure to follow the other steps for healthy eyes, as well.
Take Control of Your Eye Health
Most importantly, early detection by a professional could save your vision. There are other steps that can help, too.
Avoid vision loss and potentially catch conditions early.
Routine exams should be done at least once a year.
Get Routine Eye Exams
It’s important to get a comprehensive eye exam with dilation every year to allow for a more thorough examination of your eye and to catch conditions early, before permanent damage is done.
Some diabetic eye diseases have no signs or symptoms until they are too obvious to ignore, which might present as:
- Blurred vision
- Dark spots or "holes"
- Flashes of light
- Seeing an increased amount of floaters
- Poor night vision

Monitor Your Blood Sugar
When your blood sugar is too high, it can affect the shape of your eye’s lens, causing blurry vision, which goes back to normal after your blood sugar stabilizes. High blood sugar can also damage the blood vessels in your eyes. Maintaining good control of your blood sugar helps prevent these problems.
Monitor Your Blood Pressure and Cholesterol
High blood pressure and high cholesterol can put you at greater risk for eye disease and vision loss. Keeping both under control will not only help your eyes but your overall health.
Make Healthy Lifestyle Choices
Smoking increases your risk of diabetic retinopathy and other eye conditions, but you can reduce that risk by quitting smoking. Regular exercise also has phenomenal health benefits—it can control diabetes and improve eye health.
