These glasses are the reason I don't wear contacts anymore. They're lightweight, soooo cute, and actually comfortable to wear! I usually run into a comfort issue with glasses (hence why I always wore contacts). I also purchased the blue light blocking with them and I can honestly say that that add-on is a must when purchasing glasses in general. My eyes are no longer tired at the end of the night from “seeing” all day through these things! These glasses are amazing!!
