Photochromic Sunglasses with Anti-glare Polarized Lens

【ULTRA PHOTOCHROMIC DESIGN】This magical photochromic lens is based on the intensity of sunlight and ultraviolet light, darkening the light grey lens. 

When driving at night or in a dark environment, the lenses are bright and transparent to improve visibility while effectively reducing glare.

During the day, it can effectively filter the strong light, improve visual acuity, reduce eye fatigue, and always keep eyes in the most comfortable state during outdoor activities.
