The short version
- The American Academy of Ophthalmology says people normally blink about 15 times a minute, but only about 5 to 7 times at a screen.
- Blinking is how the eye gets the moisture it needs on its surface.
- Blink on purpose, keep a reminder on your monitor, and take regular breaks.
Simple things to try
These come from the American Academy of Ophthalmology:
- Make a conscious effort to blink often
- Put a sticky note on your screen as a reminder
- Use artificial tears when your eyes feel dry
- Consider a humidifier if you are often in a dry, warm room
- Look up at something in the distance regularly
If you wear contact lenses
The Academy notes that contact lens wearers who use screens for long periods may find dry eye an ongoing problem. Its tips are to give your eyes a break by wearing your glasses instead, not to sleep in your lenses even if they are labeled extended wear, and to keep up good lens cleaning practices.
When dry eye may be more than screens
The National Eye Institute says dry eye happens when your eyes do not make enough tears or your tears do not work correctly, and it can happen if you spend a lot of time on a computer, tablet or phone. It also says severe dry eye that is not treated can sometimes damage the cornea, so tell your eye doctor if it does not settle.

When to see an eye doctor
Screen habits are about comfort. They do not replace an eye exam, and they cannot tell you why your eyes hurt.
The American Academy of Ophthalmology says to see your ophthalmologist if:
- your eyes are consistently red, blurry or watery
- your eyes become sensitive to light
- your eyes are painful
