KNOXVILLE, Tenn. (WVLT) -- The Vision Council released a study this year reporting more than nine in 10 adults spend more than two hours each day using a digital device. All of that time can seriously affect a person's vision.
Dr. Andy Howard of the LaFollette Eye Clinic talked symptoms of digital eye strain and explained ways to protect vision on Local 8 News This Morning.
"Previous recommendations have been to reduce screen time, but I know a lot of people just can't do that. Their education depends on it, their jobs depend on it so the best way to protect your eyes from this high energy blue light that's emitted from these screens is to put something between your eyes and the screen that will block it," said Dr. Howard.
High energy blue light is what is emitted from all screens - phones, tablets, desktops. It is described as the visible light that is closest to ultra violet light.
Dr. Howard demonstrated how much light is blocked by standard lenses and how much light is blocked by a specialty lens.
"It's a great way to protect the eyes. Certainly if you have a prescription or need glasses to look at a tablet, computer or your phone; even if you don't have prescription, these lenses you can make them with no prescription at all and they still block the blue light," Dr. Howard said.
