Technology may be able to make your eyesight sharper without the use of glasses. Researchers have developed an app they say exercises the brain in ways that can improve vision.
Scientists tested out the app, called UltimEyes, on 19 players on the University of California, Riverside, baseball team.
After trying it out for 25-minute intervals, 30 times, some players became better than the normal 20/20 vision.
Amazingly, seven of them showed an eyesight of 20/7.5, being able to see at 20 feet what people with normal vision could see at 7.5 feet or closer.
The app is a workout for the visual cortex, the brain area that controls vision.
The results may seem too good to be true, but Peggy Series, a neuroscientist at the University of Edinburgh, who was not involved in the study, told Popular Mechanics that the effects are real.
“These results are, in fact, very similar to what’s already been proven in the lab,” Series says. “It’s very exciting. The fact that the app is improving the players’ visual acuity is not as surprising to me as that the improvement might actually help in playing baseball.”
