Digital Eye Strain: Why Your Eyes Feel Tired After Screen Time
By Dr. Belkis Perez, OD · Published
Digital eye strain is the group of symptoms that appear after long periods of screen use: tired or dry eyes, blurry vision, headaches, and neck or shoulder discomfort. It usually improves with breaks and better habits, but if it persists, an eye exam can rule out an uncorrected prescription or dry eye.
Why it happens
When we look at a screen, we blink less, which dries the eye's surface. Focusing up close for hours also demands constant effort. Brightness, glare, distance, and posture all play a role, and a small uncorrected prescription can make symptoms worse.
The 20-20-20 rule
The AOA recommends that every 20 minutes you look at something about 20 feet away for 20 seconds. This short break relaxes your focus and reminds you to blink.
Simple workspace adjustments
Place your screen slightly below eye level at a comfortable distance, match its brightness to the room, reduce glare from windows and lamps, and increase text size if reading is a strain. If you wear contact lenses, breaks matter even more.
When to see an eye doctor
If discomfort continues despite breaks, or you notice blurry vision at the end of the day or frequent headaches, a comprehensive exam can identify the cause: a need for computer glasses, dry eye, or other focusing issues.
