probably not for most adults
These may work for children, but I can not imagine them being OK for an adult. I don't have a huge head (7 1/4), but these pulled my glasses uncomfortably tight into my face. I got them for motorcycle riding. The idea of turning to look at something and having the wind pull my prescription sunglasses from my face is not something that contributed to enjoying the scenery. I ended up giving them away. I eventually bought ones that fit loosely over my head but ensure my glasses won't go AWOL.
