Pantographed cellulose acetate sunglasses, a material that's both solid to the touch and visually refined. The frames are crafted from sheets of cellulose acetate that have been aged and tumbled to create a shiny, glossy finish. This material is commonly used by top brands in the industry. Glasses with NEUTRAL photochromic lenses, very useful for wearers who prefer not to carry two pairs of glasses—sunglasses and prescription glasses. When exposed to UV radiation or sunlight in general, these lenses initiate a reversible chemical reaction and darken. Once the light or UV radiation disappears, they gradually return to their initial state of transparency. Dark on the outside, it turns light on the inside. It adapts perfectly to any lighting situation.
