Performance-enhancing contact lenses?

I found this to be interesting. I wore glasses/contacts for more than 20 years so I can look at this as being practical and interesting.

"They're almost like wearing sunglasses without wearing sunglasses," Roberts says. "I could tell such a huge difference right away that I was willing to give them a shot." Seven years in the making by Nike and Bausch & Lomb, the lenses — which will be known in the retail world as MaxSight — are so new they have made their way only into a few major league clubhouses so far."

FWIW, I had Lasik done four years ago and have been quite pleased with it.
