Men’s Photochromic Glasses with Glass Lenses, -3.0 Diopter

Experience the ultimate convenience with these men’s photochromic glasses. Featuring high-quality glass lenses with a -3.0 diopter correction, these glasses automatically adjust their tint based on ambient light levels. Enjoy clear vision indoors with transparent lenses that darken progressively outdoors thanks to UV activation. No need to switch between indoor and outdoor eyewear – one pair handles it all. Remember: the lenses remain clear indoors; the photochromic effect only activates in sunlight.
