I’d pay $1,000 for really smart eyeglasses. People who have LASIK surgery tend to rave about how it changed their lives for the better. Fortunately I’ve been blessed with good vision because I just don’t think I could let someone cut on my eyes unless there was no option. These surgical (?) techniques will — I assume — get better and better. That’s a good but I’m counting on eye glasses getting smarter.
A lens that could monitor what’s happening with my eyes as well as my surroundings (light, motion, etc), and adjust on the fly. Reading a book, looking at a laptop screen or a mobile device; watching TV or a movie.
One more thing. A coating on the lens that is impervious to greasy fingerprints.
