The conventional wisdom is that staring into screens will eventually worsen your eyesight. But a company called Innovision Labs reckons they can improve your vision with their smartphone/tablet app, called GlassesOff. Train your eyes for three 10-minute sessions per week, they claim, and in a matter of months you can ditch reading glasses altogether.
Here's a snippet of what the app looks like, though I sure can't tell what the hell's going on in it:
Intriguingly, the app's developers say they can improve your vision not by working on your eyes, but by working on what's behind your eyes, i.e. your brain. They claim that by exploiting neuroplasticity—the ability of your brain to form new neural connections—they can boost the brain's processing power in a way that actively improves your vision.
Here's their explanation of how it works:
Junk science, or the real deal? I'll let you know in three months; I think I'm going to pony up the $25 cost and try it, just out of curiosity.
I can justify the cost because I live in an expensive city; in Manhattan $25 barely covers two cocktails, and those always make my vision blurry.
