2-IN-1:

These cycling glasses come with two pairs of lenses: polarized and photochromic. The photochromic PC lens darkens quickly under UV exposure, blocking harmful UVA, UVB, and UVC rays. The HD black/red TAC polarized lens effectively reduces harsh light, filters reflected light and glare, and ensures clear vision.

Half-frame/Full-frame interchangeable:

The cycling glasses frame is made of TR90 material, which is very durable and not easily deformed. The lower frame can be quickly removed. Furthermore, the large, one-piece lens does not obstruct the field of vision while riding, reducing safety risks.
