Photochromic Reading Glasses for Men - Square Sports Sunglasses Readers 0~+4.00

This magical photochromic lens is based on the intensity of sunlight and ultraviolet light, darkening the light grey lens. What's more, these glasses protect the eyes without interfering with your perception of color. Plus its fashionable square design, it always matches your daily dressing demands (may not change obviously under weak UV lights). The polycarbonate lens and frames are impact and scratch-resistant, durable and unbreakable.

Designed for cycling, driving, running, fishing, climbing, trekking or other outdoor activities enthusiasts, this item features a stylish design with rich color combinations of frames and lenses. The lightweight frame with photochromic lenses makes it easy to read both indoors and outdoors.

Note that this is not a pair of sunglasses. The photochromic lens changes according to the intensity of ultraviolet rays. The stronger the ultraviolet rays, the deeper the discoloration, and the weaker the ultraviolet rays, the lighter the discoloration. (We will check carefully before leaving the warehouse)

The Photochromic Reading Glasses Lenses are clear when indoors or at night and automatically darken to a sunglasses tint when exposed to UV sunlight. Lenses will begin to clear as soon as they are away from UV sunlight, and will be noticeably lighter and mostly clear within a few minutes. They absorb UV radiation that can otherwise damage your eyes. They are an excellent solution for people who hate constantly switching between their reading glasses and their shades.

The Sports Frame is Lightweight But, for Safety Eyeglasses with Wraparound Design that Provides Increased Side Protection and Peripheral Vision. This design ensures maximum protection and comfort during various outdoor activities.
