Not only are these glasses comfortable to wear, they're a simple, classic style and, most importantly, I can really tell the difference at night when I wear them around artificial light or screens. I'm in medical school so long hours are part of the deal, including computer time with so much of our coursework online. The Smith Sleep+ are truly ideal for my situation and even for just reading a real book before going to sleep. I do need the earpieces adjusted just slightly for preference. They are a high quality product that seem like they'll last a long time with proper care which is important given the financial investment/cost. I highly recommend these if you're looking for a simple style & comfy fit. P.S. I have an oval-shaped face re: the fit, if this info is helpful to anyone.
