If you’ve ever suffered from dry, itchy, and red eyes following a long day of looking at your computer, you’ve probably been tempted to buy a pair of anti-blue light blocking glasses, which filter out the busy blue light a.k.a. Before it reaches our eyeballs, wakefulness. In accordance with the Vision Council, a group that reflects eyeglasses producers, about 60 percent of people in America surveyed experience some signals of electronic eye strain due to extended time in front of the screen, and with that fear, a cottage industry of blue lighting filtering eyeglasses has emerged during the last several years.
Rahul Khurana an ophthalmologist and a spokesperson for the American Academy of Ophthalmology noted that the effects of light on your eyes and digital eye strain are two concerns. We continue thinking of mobile telephones and our computers, but the fact is we get more exposure. It is the blue light that brings about that effect following a day. That’s why he does not recommend any special glasses for daily computer use. Eventually, “I’m not really certain how it’s going to assist with digital eye strain, which really is what’s bothering people”, says Dr. Khurana. “The digital eye strain that bothers many people can occur when you concentrate on anything, out of reading a book, looking at a screen, or watching television”, says Dr.Khurana, and it could be alleviated by moving my eyes every 20 minutes or so on something that’s 20 legs away for at least 20 seconds.
Our bodies associate blue lighting with daytime, so being exposed to it when you are attempting to go to bed pushes our internal clock later and because of this it is harder to fall asleep and harder to wake up in the morning, says Cathy Goldstein, an assistant professor of neurology at the University of Michigan Sleep Disorders Center. In a perfect world, you begin to avoid blue-enriched lighting from screens 4 hours before bedtime.
That’s hard for many individuals to swallow, admits Goldstein, therefore we do recommend blue light blocking glasses during that time. And there’s a growing body of searches to back up the claim this blocking of harmful blue lighting until bed may help you get better sleep. A more recent study of teenage boys found comparable results. If you wish to use the same blue lighting blocking eyeglasses they do in the lab, go for Uvex. The most important time to wear the glasses would be 4 hours before you plan to go to bed. This is the time that you would most benefit from wearing them.
