Polarization 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 see the world more clearly with your eyes. Suitable for travel, driving, fishing, skiing, rainy days, and outdoor sports. Photochromic Function These lenses change density depending on the amount of UV light. Outdoors with strong sunlight, they become dark like sunglasses, reducing glare. On the other hand, in spaces where UV light does not 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 different material. It is also resistant to UV light and less likely to degrade, so it is a material often used outdoors compared to general plastics. Thank you. *Transaction rules, etc., are described in my profile.
