Digital devices like computers emit a certain type of high energy light called blue light. Blue light can cause oxidative stress and be damaging to the eyes. On top of that, staring at a computer all day can cause eye strain and the longer you are on a computer, the more your eyes are affected. One thing office workers, students, and anyone who spends a lot of time looking at screens can do is follow the 20 rule. For every 20 minutes of screen time, take a break to look at an object 20 feet away for at least 20 seconds.9 Additionally, it may be of particular importance for digital device users to ensure their eyes are getting the proper nutrition. Doses of 12mg of Lutein help protect eyes from blue light.*
