It’s such a rare case in science that the scientific community seems to be in complete agreement on the issue of blue-light-blocking glasses.

What can you do to protect your eyes?

Scientists recommend taking plenty of breaks first. Staring at a computer screen is not a natural activity for our eyes, and being close to a computer screen forces the eyes to remain constricted for hours. Therefore, it is recommended to look up every 20 or 30 minutes to take a distance from your gaze.

These few minutes of rest should allow the eyes to relax. Doctors also advise respecting the distances between the eyes and the screen. For a computer, it should at least be positioned “at arm’s length” from your head. If they are too close, screen use can pose a long-term problem by causing vision loss.
