I bought these since there are days I just don't want to put in my contacts, but since I drive a lot for work, I need sunglasses. My kids laugh at me, since my regular sunglassses are designer glasses they bought me as a gift, but their really great for going over my regular eye glasses.
A bonus is the nite time glasses-I usually have a lot of trouble driving at night in the rain, and suprisingly, they work -they cut down on the glare and help the lines in the road "pop" in the rain.
Both my Uncle and Mom have ordered these after trying mine out !
