Computer Vision Syndrome (CVS)
Whether you are working from home, gaming, or scrolling on your phone, modern life demands near-constant screen time. This prolonged focus leads to a group of eye and vision-related problems known as Computer Vision Syndrome or Digital Eye Strain.
When we look at digital screens, our eyes must constantly focus and refocus. The letters on a screen are not as sharply defined as printed text, making our eye muscles work twice as hard. Furthermore, our blink rate drops by up to 66% when staring at a screen, leading to severe dryness and irritation.
Common Symptoms
Headaches & Migraines: Often originating behind the eyes or in the temples.
Blurred Vision: Difficulty shifting focus from the screen to a distant object.
Burning & Dryness: Eyes feeling gritty, sandy, or tired by the end of the day.
Neck & Shoulder Pain: Caused by poor posture and leaning in to see small text.
Dr. Fouladian's 20-20-20 Rule
The easiest and most effective way to prevent digital eye strain is to take frequent, structured breaks. Your eye muscles are just like any other muscle in your body—they cramp when overworked.
Every 20 Minutes
Set a timer. When working on a screen, force yourself to stop what you are doing every twenty minutes.
Look 20 Feet Away
Find an object in the distance (out a window or down a hallway). Looking far away relaxes the ciliary focusing muscle inside the eye.
For 20 Seconds
It takes about 20 seconds for the muscles in your eyes to fully relax. Use this time to consciously take deep, full blinks to re-wet your eyes.
Optical Solutions
Anti-Fatigue Lenses
Standard single-vision lenses aren't enough for the digital age. We prescribe "enhanced" single-vision lenses designed specifically to relax your eyes.
Essilor Eyezen®
Relax Your Eyes
Eyezen lenses contain a small, targeted "boost" of magnifying power at the very bottom of the lens. This slightly reduces the focusing effort required by your eyes when looking at close-up screens, significantly delaying fatigue.

The Blue Light Threat
Digital screens emit high-energy blue-violet light. While the sun is the largest source of blue light, the proximity and duration of our screen use cause concern. Blue light scatters easily, reducing contrast and forcing eyes to strain to maintain focus. It also disrupts your circadian rhythm, making it harder to sleep.
Our Solution: We recommend ZEISS BlueGuard or Crizal coatings to filter harmful rays and reduce glare.
The Blue Light Threat
Staring at a screen causes you to blink less often and less completely. This prevents your eyelids from spreading vital oils over your tears, causing rapid evaporation.
If specialized glasses do not resolve your burning or gritty symptoms, you likely have underlying Meibomian Gland Dysfunction (MGD).
