Feather metal frame glasses with lens size 50mm, bridge width 17mm, and temple length 135mm. These glasses have -11.5 diopter lenses for strong myopia. I recently purchased them and have only tried them on twice. I'm selling them because they don't suit me, so I'm offering them while they're still in good condition. The frame is very light and flexible, and they are very comfortable to wear ^_^ They use HOYA thin lenses for strong myopia! No claims and no returns, please.
