The ranks of the nearsighted are growing, with a study out this month from the National Eye Institute concluding that the condition has jumped from 25% of adults in the 1970s to more than 41% this decade. Researchers haven’t pinned down the exact cause (genetics can play a role) – but some are pointing the fingers at the plethora of digital screens parading before our eyes.
If you’ve used a computer, I don’t have to tell you that reading digitally is tougher on the eyes than reading the old-fashioned way. And the continual refocusing eyes do when texting or playing a video game can lead to blurred vision, headaches, and even long-term eye problems.
If someone you love is getting a new computer, video game, or cool text-friendly phone this holiday, here are a few pointers from the Vision Council:
- Best viewing distance is 18-28 inches from a computer screen, and four to five times the width of a TV screen.
- Lower-intensity light is best, so close drapes and lower indoor lights.
- Contrast and brightness of your TV or computer screen should be relatively the same as the environment.
- Follow the 20-20-20 rule: Take a 20-second break every 20 minutes, and focus your eyes on something at least 20 feet away. Then blink slowly 10 times to relax and rewet the eyes.
