Osan glasses protect from harmful rays, blue light rays. And they absolutely do not cause you headaches, are comfortable for the eyes, and are light, you don't feel them. The two glasses are complete with all their accessories, new in their original packaging, never worn since I received them. I kept them in their box and everything that came with them is new. Give me your price, and may God bless you. If you are serious, contact me privately, and we will not disagree, God willing. If you want one pair of glasses, send me a private message.
