Spending long periods looking at computer, phone, or tablet screens can strain the eyes. Using the 20-20-20 rule can help to prevent this problem.

The rule says that for every 20 minutes spent looking at a screen, a person should look at something 20 feet away for 20 seconds.

Following the rule is a great way to remember to take frequent breaks. This should reduce eye strain caused by looking at digital screens for too long.

When following the rule, a person takes a 20-second break from looking at a screen every 20 minutes. During the break, the person focuses on an object 20 feet away, which relaxes the eye muscles.

The following methods can help a person to put this rule into practice:

  • Set an alarm for every 20 minutes while working, as a reminder to take a break.
  • Download an app developed to help people follow the 20-20-20 rule. The ProtectYourVision and eyeCare apps are some examples.
  • Look out a window during the 20-second breaks. Judging a distance of 20 feet inside can be difficult, but focusing on a tree or lamppost across the street should work well.

Alternately, a person can benefit from closing their eyes for 20 seconds every 20 minutes. Also, remembering to blink can prevent dry eye by encouraging tear production.

Anyone who spends the day sitting should periodically get up and walk around, to prevent back and neck pains.

Light sensitivity, or photophobia, is more than just a nuisance—it can significantly affect daily life. People with dry eye, migraines, post-surgery eye conditions, or certain autoimmune disorders often struggle with harsh lighting, glare, or outdoor sunlight.

Depending on the severity of photosensitivity, 7eye offers light sensitive customers 4 different extra dark lens options in category 4 and category 5.

This tiered model gives flexibility depending on context — office work, outdoor activities, driving, extreme photosensitivity — which makes Ziena’s collection suitable for a wide range of needs.
