68% of Millennials Report Digital Eye Strain

If you're one of the nearly four in 10 millennials or one-third of Gen Xers that spend at least nine hours on a digital device each day, you could be putting the health of your eyes at serious risk. A recent study from the Vision Council suggests that 68% of millennials report suffering from the effects of what is known as "digital eye strain."For most of us, looking at screens throughout the day is utterly unavoidable. The simplest way to try and avoid digital eye strain is take breaks from staring at your computer screen as often as you can. However, guidelines differ on exactly how often you should take a break from your display.
The Vision Council advocates a "20-20-20 break": Every 20 minutes, take a 20-second break and look at something 20 feet away.
The Canadian Ministry of Labor suggests a five–minute break away from computer operation for every hour worked.
