I recommend buying your glasses from
http://www.39dollareyeglasses.com. You can get two pairs of glasses for the price of one pair from Lenscrafters and the quality and finish are just as good. You can even mix & match prescriptions by getting maybe a Transitions pair for every day wear and a sunglass pair for when the sun's really bothering your eyes. If you really want a terrific deal, check out
http://www.zennioptical.com. You can get two pairs of high quality glasses for under $100! The reason Lenscrafters is expensive is they sell brand name glasses and every store has to have their own one hour optical laboratory which raises the price. If brand name's not that important to you, you can still have a nice set of glasses and last time I checked no one cared what name you had on the glasses you wear.
My Calvin Klein sunglasses were about $150 ($99 frames). Not that I care what name is on the glasses...it was just the only frames I liked. (So many glasses today are these itty bitty skinny lenses that used to be popular with old ladies.)
My friend use to mock my 'cocoon' style glasses. Now he just mocks my CKs. (Some friend!)
