It's official! Winter is here, which means in some parts of the country bitter cold winds and cold precipitation are also in the forecast. Most of us wouldn't ever conceive of leaving the house without a heavy sweater or coat in cooler climates, but surprisingly, a lot of people leave their sunglasses at home. While the sun may not be our primary concern during times that we are bundling up against the bitter winter climate, the sun is still shining down in colder climates, and in many instances can be even stronger.

If you find yourself snowed in, it is wise to be extra cautious. Particularly in the aftermath of a blizzard, the world around takes on a sparkling glow due to the sunlight reflecting off of the water molecules blanketing the ground and the trees. In fact, for many it can be painful to open your eyes when you first leave the house after a heavy snow. The UV exposure that we are all so careful in avoiding in the summer months can really be more hazardous in the winter due to the fact that it reflects off the snow or ice, resulting in a second exposure. This is why proper sunglasses are a necessary part of your winter attire.

Even though 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. Check that your sunglasses block 100 percent of UV rays by checking for confirmation that they block all light up to 400 nanometers - UV400. Don't worry, you don't necessarily have to pay more to guarantee complete protection from the sun. Dozens of affordable options exist that still provide total UV protection.

Another important feature in choosing sun wear is frame size. You want to make sure the lenses are large enough to completely shield your eyes and if possible the areas around them as well. The more coverage you have, the less harmful radiation will be able to penetrate. Lenses that wrap around the temples will also stop radiation from sneaking in through the periphery.

For those who enjoy snow or ice sports, it’s important to know that the sun's rays are more powerful at higher altitudes, so be especially sure to protect your eyes on the ski slope. Another way to add extra protection is to wear a protective hat with a wide brim or visor.

This wintertime, keep warm and stay protected! Make your sunglasses a fixed part of your routine.
