Winter Sun Exposure and Your Eyes
It's official! Winter is here, which means in some areas whipping winds and cold rain, snow and sleet are also on the horizon. You wouldn't ever conceive of leaving the house without a jacket in overcast climates; nevertheless unfortunately, many people leave their sunglasses at home. Although many of us aren't thinking about the glaring sun during times that we are venturing out to the freezing winter climate, the sun is still shining down during the winter months, and in many instances can be even stronger.
They don't call it a "winter wonderland" for no reason. In particular after a blizzard, the blanket of snow covering the ground, trees and everything else in sight, actually intensifies the reflection of the sun. In fact, for many it can be painful to open your eyes when you first leave the house after a heavy snowfall. The ultraviolet radiation that most of us are so careful in protecting ourselves against in the heat of the summer may really be more dangerous in the colder season since it bounces off the snow or ice, giving you a double dose of exposure. This is why sunglasses are an essential part of your winter attire.
Even though you want to feel great in your shades, the most important consideration when choosing sunglasses is making sure they will properly protect your eyes. Make sure your sunglasses block 100 percent of UV rays by looking for confirmation that they are labeled UV 400 (this means they block all light with wavelengths up to 400 nanometers, which includes both UVA and UVB rays.) The good news is you don't necessarily have to purchase designer glasses for adequate coverage for your eyes. Dozens of inexpensive brands are made with complete ultraviolet protection.
Another important factor in picking the right sun wear is the size of the lenses. You want to make sure your glasses cover as much of the area around your eyes as possible. The larger the surface area covered by your sunglasses, the less harmful radiation will be able to penetrate. Wrap around frames will also keep radiation from sneaking in through the periphery.
For those who enjoy snow or ice sports, you should know that UV rays are more powerful at higher altitudes, so be even more careful to guard yourself on the slopes. For added protection add on a wide brimmed hat that covers your eyes.
This winter, keep warm and keep your eyes safe! Make your sunglasses a fixed part of your routine.
