From LensCrafters’ Frequently Asked Questions page:

Q. Can I buy glasses without a prescription in the lenses?
A. Yes, we call them plano lenses. You can get them with the same great options as prescription lenses, including hip tints and anti-reflective and scratch resistant coatings. Don’t forego a great fashion accessory just because you have good vision.

Really?  That’s asked frequently, is it?  People who want to buy $200 glasses just so they can wear glasses?
