Seeing is Believing

I blew $400 today on a pair of glasses. I know, what could be more of a waste of money to spend on than your eyes? I guess maybe your teeth. Anyway, it turns out eventually I'll need three different pair of glasses. One for reading, another for the computer, and eventually one pair for driving.
Now though, just reading and computer glasses.
My sister says I should consider taking Lutein.
Sheesh.
