I've been ordering from Zenni Optical for over a year now and am so happy with the idea of getting some pretty wacky prescription frames without having to shell out big money... Plus I don't have a valid prescription so this site is perfect. Only problem is that you can't try before you buy, so I usually order a few pairs (because they are so cheap) & usually at least one of them work for my face.
Here is the pair I just ordered tonight and am crossing my fingers that they are a winner.
They do have a feature where you can "virtually" try them on.
It's not a perfect science but at least it's something.
My new frames with lenses for $25.95. (opted for the anti-reflective coating for an additional $4.95)
Grand total with shipping for prescription frames: $35
I hope I love them.
