The sizing on these frames is deceptive. They are definitely not all that small. While the measurements shown are accurate the screws sit inboard of the arms meaning the frame width (screw to screw) shows as narrower than comparable frames. In the end this is not a useful measurement and the lens width is more indicative of a medium size frame which is how these should be categorized. For my needs this is a problem. Beyond that the frames OK, they feel s bit cheap. The arms have some flex to them. My prescription was made accurately and everything seems well put together.
