I have ordered from the above two companies. Very pleased. The eye doctors are horrified when you do this. I used to pay $300 for single vision lenses and frames at Lenscrafters. ONE pair.

http://glassyeyes.blogspot.com i am nearsighted and over 40, in bifocals. I have been very pleased. Having a choice of two or three pairs is a real luxury! My latest scrip I got from goggles4u. $10 for frames, $38 for bifocal lenses with lines.
As the person above said, the frames with wire nose pieces and plastic pads are adjustible and don't slide down your nose like the all plastic frames do.
When you get your scrip from the doctor, be sure and get your PD (pupillary distance) as well. That's how far apart your eyes are, in millimeters, so they know where to put the optical center of the lens.
