The glasses and sunglasses sold in our store generally have replaceable lenses. You can replace them with various lenses, such as prescription lenses, color lenses (so-called sunglasses), and photochromic lenses that change color when exposed to ultraviolet light. Prescription lenses can be made if you have lens data, such as a glasses prescription obtained from an ophthalmologist. For example, even if the design seems unusual, the lens structure itself is not complicated, so they can be replaced.
