Computer screens and healthy eyes
Blink. And take frequent breaks. And remember what your parents said: “Don’t sit so close!”
Blinking is important.
Normally we blink about 20 times per minute. If we’re reading, we only blink about 15 times. When staring at a digital display this number reduces to only 8 times a minute.
So in a nutshell: Computer screens = Less blinking = Dryer eyes that are prone to strain and fatigue.
The 20/20/20 Rule
Fight digital eye strain with this simple tip:
Every 20 minutes, look out 20 feet away for 20 seconds. This reminds us to blink and relaxes the muscles in the eye used for reading up close.
The Blue-Light Problem
Decreased blinking isn’t the only problem. Digital devices like computers, tablets and phones are constant sources of high-energy blue light (the part of the spectrum of light that doesn’t necessarily damage your eyes, but causes strain and fatigue in high amounts).
