Also wanted to add, the glasses themselves are a little on the cheap side in feel, and in smoothness when opening and closing the arms, and they do not have the springs that allow them to stretch wider. They do have nice long arms on them, something my hubby has a hard time finding, and the tortoise are nice unisex frames. Overall, I would recommend these to anyone struggling with blue light issues.
