(As Dad might say.)
Nike and Bausch and Lomb have developed contact lenses for sports professionals that block out UV rays and unnecessary color information, making it easier for baseball hitters to see the seams on a ball, for example.
Imagine the possibilities for beauty, though. When you essentially wear sunglasses on your eyes, you won’t have to squint as much, meaning you’ll develop fewer wrinkles over time. (The colors of the lenses are also pretty striking.)
Hell, these could be marketed to anyone who’s outside a lot. Think about truckers. Sure, they can wear sunglasses, but those can fall off or break or be misplaced easily. When you’ve got stuff in your eyes, you tend to leave it there until you’re done with it for the day. “Never lose your sunglasses again!”
I just think the whole idea is cool.
