Women's Polarized Photochromic UV400 Sunglasses - Brown Frame / Yellow Lens Cool, polarized photochromic UV400 sunglasses. The lenses are yellow. They make it much easier to see in poor visibility conditions such as at night, in fog, or when it's snowing. Photo 2 shows how they look when worn. Beautiful! Photo 3 shows the lenses after being exposed 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. Included: Sunglasses Eyeglass case Drawstring pouch Also available in black and pink. Polarization Function: Eliminates glare and effectively reduces strong light, reflected light, and scattered light. Converts chaotic light into parallel lines, making your vision clearer and softer. Let's you see the world more clearly with your eyes. Suitable for travel, driving, fishing, skiing, rainy days, and outdoor sports. Photochromic Function: These lenses change their tint depending on the amount of UV light. Outdoors in strong sunlight, they become dark like sunglasses, reducing glare. On the other hand, indoors, where UV light doesn't reach, they become clear like regular glasses, ensuring a bright field of vision. The degree of color change in the lenses also varies with temperature; they will be lightly tinted in the high temperatures of summer and more darkly tinted in the low temperatures of winter. UV400: 99% UV cut rate 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 different material. It is also resistant to UV light and does not degrade easily, so it is a material often used outdoors more than general plastics. Thank you. *Transaction rules, etc., are described in my profile.
