I purchased these glasses because I saw that they were extremely lightweight, and I have frequent migraines and thought it might help. They definitely seem lighter and are quite comfortable. I didn't care how they looked so much, but now that I have them I really like the look of them too. I thought they might be oversized and slide off my face, as most glasses today seem to do, but they stay put and are a nice size for my face. The material isn't the typical slick, shiny plastic, but a matte, brushed plastic. It did take about 3 weeks to receive the glasses which was fine.
