It's official! Winter is here, which means in some locations biting winds and freezing rain, snow and sleet are also on their way. You would never even think of leaving the house without a jacket in cooler conditions, however surprisingly, a lot of people leave their sunglasses behind. While many of us aren't thinking about the shining sunshine during times that we are battling the frigid winter climate, the sun is still a present danger during the winter months, and in certain circumstances can be even stronger.

For times when you frequent an area with snow, you should be even more careful. In particular in the aftermath of a heavy snow, the world around takes on a glistening glimmer thanks to the sun's rays reflecting off of the water molecules blanketing the earth. In fact, for many it can hurt to open your eyes when you first leave the house following a fresh snowfall. The ultraviolet radiation that we are all so vigilant in protecting ourselves against during the summer may really be more dangerous during the wintertime due to the fact that it reflects off the snow or ice, giving you double exposure. This is the reason proper sunglasses are a necessary part of your winter wardrobe.

While you want to look great in your sunglasses, the most important part of choosing sunglasses is being certain they will properly protect your eyes. Make sure your sunglasses block 100 percent of UV rays by checking for an indication 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.) Don't worry, you don't necessarily have to purchase designer glasses for complete coverage for your eyes. Many of the more affordable brands are made with complete defense.

Another important consideration in picking the right sun wear is the size of the lenses. You will have the most protection when the lenses totally shield your eyes and if possible the surrounding areas. The more coverage you have, the less harmful radiation will be able to enter. Wrap around frames will also keep UV waves from sneaking in from the sides.

For those who enjoy snow or ice sports, you should know that the sun's radiation is more powerful at higher altitudes, so you need to be even more careful to keep your eyes covered on the ski slope. Another way to add extra protection is put on a protective hat with a wide brim or visor.

Make a point to be knowledgeable about the dangers of the sun's radiation to your eyes all year long. Make your sunglasses a fixed part of your routine.
