The benefits of wearing sunglasses when it's snowing
Wearing sunglasses in winter skiing is not only for good looks, but more importantly, to cover the eyes. Especially sunlight reflecting through water, snow or wet pathways can make it hard to keep your eyes open in the snow. So try to wear polarized sunglasses when skiing. Also available as photochromic lenses with polarized properties, photochromic lenses provide you with ideal visual acuity, visual comfort and excellent UV and glare protection, automatically responding to changing lighting conditions: from transparent colors indoors to black in the sun, and sunlight in the sun outdoors.
Although the sunlight is weakened in winter, the ultraviolet rays are not much less, which will also cause damage to the eyes. Especially when it snows, the reflectivity of the snow to sunlight is as high as 95%, and the brightness level of the snow surface is close to the sunlight.
Looking directly at the snow surface is equivalent to looking directly at the sunlight. If people work in the snow for a long time without wearing goggles, the ultraviolet rays reflected by the snow will be received by the human eyes, resulting in tears, redness, swelling, pain, itching, and a foreign body sensation in the eyes. Commonly known as "snow blindness". Therefore, it is best to wear sunglasses or other goggles when going out in heavy snow or during activities to prevent the strong light reflected from the snow from damaging your eyes.
