I found out about Warby Parker after I decided to get a new pair of glasses and thought "by now, there must be a good way to do this online". Sure enough, I found them.<p>Very cool company. They let you pick out 6 pairs of frames and ship them to you free of charge, along with a free UPS return sticker. It's an relatively easy way to browse an online selection of frames and see what works best for you. This process is a lot better than the standard "upload a photo and we'll superimpose a picture of the glasses on top of it" model that most sites use. The downside is it may take a couple weeks to find a frame you like, and I think they only sell plastic frames.
