Women's Sunglasses - Polarized Photochromic UV400 - Pink Cool polarized photochromic UV400 sunglasses. Photo 2 shows an example of them being worn. Beautiful! Photo 3 shows them after being exposed to a UV lamp for about 10 seconds. The lenses darken in response to UV light. Photo 5 shows the decorative elements on the sides. The hinges are also well-made. Don't miss this opportunity. Thank you. (Note: "ra." is likely a typo or informal interjection.) We also have black, champagne, and purple colors available. Polarized Function Eliminates glare and effectively reduces strong light, reflected light, and scattered light. It aligns scattered light into parallel lines, making your vision clearer and softer. See the world more clearly through your eyes. Suitable for travel, driving, fishing, skiing, rainy days, and outdoor sports. Photochromic Function The lens concentration changes depending on the amount of UV light. In bright sunlight outdoors, the lenses become dark like sunglasses, reducing glare. Conversely, in indoor spaces or areas with no UV light, they become clear like regular glasses, ensuring bright vision. Furthermore, the degree of color change in the lenses also varies with temperature. In hot summer weather, they will develop a lighter tint, while in cold winter weather, they will develop a darker tint. UV400 UV cut rate: 99% Frame Material PC (Polycarbonate): Polycarbonate is a plastic that is incredibly strong, resistant to heat, and possesses unique properties. It is also highly resistant to UV degradation, making it more suitable for outdoor use than common plastics. Thank you. *Please check my profile for transaction rules.
