Both polarized lens sunglasses and ordinary sunglasses have the effect of preventing ultraviolet rays and reducing the intensity of light. The polarized lens uses the linear molecular arrangement inside the lens to re-organize the irregular reflected light and achieve the effect of filtering all kinds of glare that damage the eyes, so that the light that enters the eye is clearer and more natural. Our polarized lenses can filter out more than 99% of ultraviolet rays in sunlight, and their filtering performance meets the requirements of international standards. The lens has a standard optical arc design to form an optical visual axis to produce a visual image. The eye frame is firm, the frame material is excellent, and it has an optical function design, and it feels comfortable and safe after wearing.
