What Is Digital Eye Strain?
Digital eye strain—also called Computer Vision Syndrome (CVS)—is a group of eye and vision problems caused by prolonged screen use. It affects up to 90% of people who work on computers.
Symptoms include:
- Dry, irritated eyes
- Blurred vision
- Eye fatigue and heaviness
- Headaches (especially behind the eyes)
- Difficulty focusing between distances
- Light sensitivity
Why Screens Strain Your Eyes
Several factors make screens uniquely harsh on your eyes:
- Reduced blinking — You blink less when focusing on screens, leading to dry eyes
- Blue light exposure — High-energy visible light may contribute to eye fatigue
- Close focus distance — Your eyes work harder to focus on nearby objects for hours
- Glare and reflections — Your eyes constantly adjust to screen brightness
- Small text and pixels — More effort to process than printed text
The 20-20-20 Rule
Every 20 minutes, look at something 20 feet away for 20 seconds.
Why The 20-20-20 Rule Works
This simple practice:
- Relaxes the focusing muscles inside your eye
- Triggers more frequent blinking
- Reduces cumulative strain on your visual system
- Gives your brain a micro-break from intense visual processing
The problem: Nobody remembers to do this. You're focused on work. 20 minutes passes, then 40, then 2 hours. Your eyes are screaming but you're "almost done."
You Need an Annoying Reminder
Silent notifications don't work—you dismiss them without looking away from the screen. Pop-ups get closed. Phone alarms get snoozed.
You need something that actually interrupts you. Something you can't ignore.
