Oosan glasses protect from harmful rays, blue light rays. They never cause headaches, are comfortable for the eyes, and are so light you won't feel them. Both glasses come with all their accessories, are new and still in their original packaging, never worn. They were given to me and I kept them in their box with everything new. The price for both glasses is 400, and the original price for each pair is 250 on the website. Please only serious buyers to contact.
