The Winter Sun and Your Eyes
Winter has officially arrived, which means in some locations biting winds and frigid precipitation aren't far behind. You would never even think of leaving the house without a jacket in icy conditions; nevertheless surprisingly, many people leave their sunglasses at home. Although the sun isn't always our first concern during times that we are bundling up against the frigid cold, the sun's rays are still a present danger in colder climates, and in certain circumstances can be even stronger.
They didn't write a song called "winter wonderland" for nothing. Especially after a serious snow fall, the blanket of snow covering the ground, trees and everything else in sight, actually magnifies the reflection of the sun. In fact, it can downright hurt your eyes when you first step outdoors following a fresh snow. The ultraviolet exposure that many people are so careful to avoid in the heat of the summer may really be more dangerous during the winter months because it reflects off the snow or ice, resulting in double exposure. This is the reason a good pair of sunglasses is a crucial part of your winter attire.
While you want to pick a style you look good in, the most important part of choosing sunglasses is making sure they will properly protect your eyes. Ensure your sunglasses block 100 percent of UV rays by checking for an indication that they block all light up to 400 nanometers - UV400. The good news is you don't necessarily have to pay more for adequate protection for your eyes. Dozens of inexpensive brands are made with full defense.
Another important feature in selecting sun wear is lens size. You will have the most protection when your glasses are large enough to completely shield your eyes and the areas around them. The larger the surface area covered by your sunglasses, the less harmful radiation will be able to get past your sunglasses. Glasses with side shield will also keep UV waves from entering through the periphery.
Just as most people are aware that sunglasses are critical to wear at the beach since the water intensifies the sun's rays, this is also true for frozen water sources including ice and snow. Consequently it is equally important to wear sunglasses when out in wintery conditions. Also ultraviolet radiation is more forceful at high altitudes, so if you have plans to hit the slopes, have this in mind.
This wintertime, stay warm and keep your eyes safe! Don't leave home without your shades.
