Purchased in April 2025 and used about twice. I'm reluctantly selling it because I don't use it often even though I bought it. The lenses are photochromic. When decolorized, they are about 25% (blue), and when exposed to UV light, they tint up to a maximum of 80% (dark blue). The lenses are non-prescription. They do not react to visible light, so they do not tint inside vehicles. They only tint in response to UV light. The price includes the cost of the lenses. Includes the glasses case and cleaning cloth. (Both are original.) No separate sales (lenses only or frame only). Stylish design glasses, Sugimoto Kei KS-175 model, black and silver. - Brand: Sugimoto Kei - Model: KS-175 - Color: Black/Silver No claims and no returns.
