Thank you for viewing my many products. These photochromic sunglasses change lens color with UV rays! Two functions in one. This is a convenient item that automatically switches between "fashionable glasses" with an intellectual impression indoors and "sunglasses" that look cool outdoors. The popular browline (brow) style can be worn with a wide range of outfits, from casual to formal, and the design is suitable for both men and women. With UV cut, they are perfect for upcoming camping trips, drives, and outings! Product Features Photochromic Lenses: The lens darkness changes according to the strength of UV rays. Popular Design: Classic browline frame.
