The Dangers of the Sun to Your Eyes - In the Winter
Winter is officially here, which means in some areas whipping winds and freezing precipitation are also in the forecast. The majority of us would never even contemplate of leaving the house without a jacket in overcast climates, but unfortunately, many people don't think to take their sunglasses. Although the sun may not be our primary concern during times that we are battling the frigid cold, the sun is still a present danger in colder climates, and in certain circumstances can be even more powerful.
If you frequent a location with snow, you should be extra cautious. Especially in the aftermath of a snow storm, the world around takes on a sparkling glow as a result of the sun's rays reflecting off of the water molecules blanketing the ground and the trees. In fact, without sunglasses it can be painful to open your eyes when you first step outdoors after a heavy snow. The ultraviolet exposure that most people are so vigilant about during the heat of the summer can really be more dangerous during the colder season since it bounces off the snow or ice, giving you a second exposure. This is why a good pair of sunglasses is an essential winter accessory.
Even though you want to pick a style you look good in, the most important part of selecting sunglasses is making sure they will properly do their job. Check that they are 100% UV blocking by looking for confirmation that they block all light up to 400 nanometers - UV400. Don't worry, proper sun protection isn't necessarily expensive. Dozens of reasonably priced brands are made with complete defense.
Another important factor in selecting sun wear is size. You will have the most protection when your glasses are large enough to completely shield your eyes and the surrounding areas as well. The more coverage you have, the less harmful UV rays will be able to enter. Glasses with side shield will also prevent UV waves from entering from the periphery.
Although it's much more commonly known these days that sunglasses are critical to wear at the beach because the water intensifies the sun's rays, this also applies to wintery water as well. Therefore it is equally important to wear sunglasses when out in the snow. Also UV radiation is stronger at high altitudes, so if you have plans to hit the slopes, have this in mind.
Be knowledgeable about the risks of UV damage to your eyes throughout the year. Make wearing your sunglasses a fixed part of your routine.
