[UNDERGROUNDJOBS] Photochromic Polarized Sunglasses for Men and Women - Driving, Cycling, Fishing, Baseball, Running - Ultra-lightweight - Colored

[Photochromic Lenses] The photochromic dye coated on the lens changes color when exposed to UV (ultraviolet) light, altering its molecular shape. In places with high levels of UV light, such as outdoors, the lens color darkens, transforming it into sunglasses. The lens only changes color when exposed to UV light, and since the original lens color is light, it can be used indoors without any discomfort. *Notes on photochromic lenses: The color change of photochromic lenses varies depending on temperature, UV light level, and lens angle. They will not change color when viewed through UV-cut glass, such as indoors or inside a car. [Polarized Lenses] Polarized lenses cut out dazzling light that obstructs vision with a polarizing film, making it easier to see. They eliminate glare and ensure a clear field of vision, making them useful in a variety of situations, such as driving and fishing. [Lightweight Frame] The frame is made of durable TR90 and aluminum alloy, which is also used in baby bottles, making it lightweight and durable.
