Women's Sunglasses Polarized Photochromic UV400 Black Cool, polarized photochromic UV400 sunglasses. Photo 2 shows an image of them being worn. Beautiful! Photo 3 shows the result of exposing them to a nail UV lamp for about 10 seconds. The lenses darken in response to UV light. Photo 5 shows the side decoration. The hinges are also well-made. Don't miss this opportunity! I also have pink, champagne, and purple available. Polarized Function Eliminates glare and effectively reduces strong light, reflected light, and scattered light. Converts chaotic light into parallel lines, making the view clearer and softer. Let's you see the world more clearly with your eyes. Suitable for travel, driving, fishing, skiing, rainy weather, and outdoor sports. Photochromic Function These lenses change density depending on the amount of UV light. In strong sunlight outdoors, they become dark like sunglasses, reducing glare. On the other hand, in spaces where UV light doesn't reach, such as indoors, they become clear lenses like regular glasses, ensuring a bright view. Also, the degree of color change in the lenses varies depending on the temperature; they develop a lighter color in the high temperatures of summer and a darker color in the low temperatures of winter. UV400 UV cut rate is 99% Frame Material PC: Polycarbonate is a plastic that won't break even if hit with a hammer, and is also very heat-resistant, yet has properties like a completely different material. It is also resistant to UV light and doesn't degrade easily, so it is a material often used outdoors more than general plastics. Thank you. *Transaction rules, etc., are described in my profile.
