I had a doubt about size 58, but they fit perfectly on an adult with a round face. They are lightweight glasses, the frame does not bother the nose or the cheeks because the arms are elastic and they sit well on the face without causing any discomfort.
The gray color is somewhat light, I would prefer it a bit darker (but that's a matter of personal preference). They come with a nice hard case with a zipper and also a soft pouch from the company. Overall, they are good for their price
