What Is Computer Vision Syndrome?
Computer Vision Syndrome (CVS), or digital eye strain, is a set of vision problems. These issues come from using screens for a long time. It affects people of all ages and lifestyles, from remote-working professionals to students and even casual smartphone users.
Some of the most common symptoms of CVS include:
- Blurry vision
- Dry or watery eyes
- Headaches
- Eye strain or fatigue
- Neck and shoulder pain
- Difficulty focusing after looking away from the screen
If that sounds familiar, you’re not alone. The average person spends over 7 hours a day looking at screens. And for many, that number is even higher.
Why Do Screens Cause Eye Problems?
When you focus on a screen for extended periods, several things happen that can throw your visual system off balance:
- Blink rate drops dramatically. Most people blink 50–60% less while staring at a screen, which leads to dry, irritated eyes.
- Focus fatigue sets in. Your eyes are constantly adjusting focus—especially when switching between screens, documents, and lighting environments.
- Blue light exposure increases. High-energy visible (HEV) light from screens can interfere with sleep cycles and may contribute to eye strain over time.
- Posture and setup matter. Poor ergonomics (like screen height, lighting, or seating position) can cause visual stress and physical discomfort.
Digital devices demand constant visual attention, which doesn’t give your eyes a chance to rest. Over time, this strain adds up, especially if you’re not using proper eyewear or workspace habits.
How to Reduce Digital Eye Strain
Fortunately, you don’t have to give up your screens to protect your eyes. With a few simple changes, you can dramatically reduce the impact of computer vision syndrome:
1. Follow the 20-20-20 Rule
Every 20 minutes, look at something 20 feet away for at least 20 seconds. It gives your eyes a much-needed break and helps reduce focus fatigue.
2. Adjust Your Workspace
Keep your screen about an arm’s length away and position it so the center of the screen is slightly below eye level. Avoid glare from overhead lights or windows.
3. Use Artificial Tears
Lubricating drops help restore moisture and comfort. If your eyes feel dry or gritty while using screens, a preservative-free drop can offer fast relief.
4. Wear the Right Glasses
If you wear prescription glasses, make sure they’re updated. You might benefit from lenses with blue light filters or a special anti-fatigue design made for screen use.
5. Limit Screen Time Before Bed
Reduce exposure to blue light at night to help your eyes relax and improve your sleep quality. Avoid screens for at least an hour before you go to sleep if possible.
Is It Just Eye Strain, or Something More?
While digital eye strain is common, it’s not the only cause of blurry, tired eyes. If your symptoms are frequent or getting worse, it could be a sign of another issue like:
- Dry eye disease
- Uncorrected vision problems
- Early presbyopia (age-related focusing difficulty)
- Binocular vision imbalances (how your eyes work together)
The only way to know for sure is through a comprehensive eye exam. At BenNissan Eyes, we’ll check your visual acuity, focus, eye alignment, and tear health to determine the root cause of your discomfort.
