Winter is officially here, which means in some parts of the country bitter cold winds and cold rain, snow and sleet aren't far behind. You would never even think of leaving the house without a jacket in icy climates, however surprisingly, many people don't think to wear sunglasses. While many of us don't think about the shining sunshine when we are bundling up against the freezing winter climate, the sun is still shining down in colder climates, and in certain circumstances can be even more powerful.
They didn't write a song called "winter wonderland" for no reason. In particular after a blizzard, the world around takes on a glistening glow due 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 heavy snowfall. The ultraviolet radiation that we are all so careful in protecting ourselves against in the summer may really be more hazardous during the wintertime due to the fact that it reflects off the snow or ice, giving you double exposure. This is why a proper pair of sunglasses is a crucial winter accessory.
While it's important to pick a style you look good in, the most important consideration when selecting sunglasses is checking that they provide adequate protection against UV. Make certain your sunglasses block 100 percent of UV light by checking for an indication that they block all light up to 400 nanometers - UV400. The good news is proper sun protection doesn't mean you have to buy the most expensive pair. Many of the more inexpensive options exist that still provide complete ultraviolet defense.
Another important factor in choosing sun wear is size. You will have the most protection when your glasses totally cover your eyes and if possible the surrounding areas. The larger the surface area covered by your sunglasses, the less harmful UV rays will be able to penetrate. Wrap around frames will also prevent harmful rays from entering from the periphery.
Although it's much more commonly known these days that sunglasses are essential to wear on the water because the water intensifies sunlight, this is also true for wintery water as well. Consequently it is equally critical to put on sunglasses when out in the snow. Additionally ultraviolet exposure is more powerful at high altitudes, so if you are skiing or snowboarding, take this into consideration.
It's important to be in the know about suitable eye protection throughout the year. Don't forget to wear your sunglasses.
