These are the glasses I received from Zenni Optical. They were very inexpensive at $8 for each of the "normal" frames/prescriptions and about $25 for the goggles. I needed new glasses because my obscenely expensive designer frames, Oakley and Versace from LensCrafters, both broke after less than a year. :-( My wife told me about Zenni Optical after hearing about them through the grape vine. Their website is fairly straightforward and I only had to wait about 3 weeks to get my order from Hong Kong/China. The glasses fit nicely, are fairly good quality, and the prescription seems to be spot on. Overall, I give them a solid B+. I would have given them an A, but 3 weeks is a long time to wait. Total cost: ~$50 for 3 glasses and shipping.

PS Yes, I know my glasses are kinda nerdy or BC glasses (birth control glasses, meaning I won't get laid in them). The goggles are for when I am riding my bike/motorcycle and/or running.
