Choose either non-prescription or prescription lenses with a blue light filter to reduce exposure to blue light from the sun and artificial sources.
Blue light is all around us. It comes primarily from the sun and it's what makes the sky look blue. Artificial blue light can also be found in things like computers and flat screen televisions, LED lights and energy-efficient light bulbs.
Our skin, nails, hair and eyes all contain melanin, the body's natural "sunscreen" which absorbs UV, and while our eyes have natural filters, these filters do not filter out all blue light so it reaches the retina.Many U.S. adults spend a minimum of six hours a day, every day on phones, tablets and computers. Digital devices fit so naturally into our daily lives that it's easy to forget how "unnatural" it is for our eyes to work, read and play from a digital display for hours. With the increased use of digital devices, we are exposed to more blue light overall from both natural and artificial sources.
More than half of U.S. adults – 60 percent – spend a minimum of six hours a day, every day on phones, tablets and computers, so it's important to practice good habits to keep your eyes safe from blue light. Because we use our electronic devices so regularly, we are gradually being exposed to more sources of this light for longer periods of time.
Many adults who use devices regularly and who experience eye discomfort didn't do anything to ease their symptoms. Schedule an eye exam to make sure you're doing everything you can to reduce exposure to blue light in your daily environment. * Ide T, Toda I, Miki E, et al.
