For those of us who frequently spend our days in front of computer screens, yet also seem to be living in caves so as to have not heard of all the hot new eye-related fads, here's a fun little something I just discovered.
Every 20 minutes of reading, especially at a computer screen, should be broken up by 20 consecutive seconds of staring intently at an object 20 feet away, according to both The Mayo Clinic and Oregon State University. This helps get the human eye focused and blinking, which is good for it. I'm sure other sources agree, but two seems to suffice.
I haven't tried it yet, but I may do so and report back.
(Countdown timer included.)
