My last 2 pairs are not 40.00, but they are only $60.00 and have optics equal to glasses of 3x their price. Things like decentered lenses, etc.

Tifosi Optics, I use the pave model. You can get them in clear, tinted, or photochromatic that change as light changes.

You can even check out their athletes page and see other cyclists use em, for that 'look like a pro' feeling, lol.
