Persuasive Essay On Snow
Snow is cold, requires frequent removal from driveways, and makes driving difficult. These aspects of snow make winter the least favorite season for many people. However, for those "in the know" about winter sports, winter is an easily tolerated or even favorite time of the year. The cold aspect of this season is easily tolerated by engaging in active winter sports and using the proper gear. You can downhill ski, cross-country ski, snowshoe, ice skate, snowmobile, or go sledding with your kids. Of course, these are just a small sampling of the winter sports available.

activity. However, eye damage from ultraviolet (UV) rays is a risk common to all outdoor winter sports involving snow and sun exposure. Snow reflects UV rays into your eyes from many directions. At minimum, you should wear sunglasses that block both UVA and UVB. Make sure the label states this. A pair of dark tinted glasses doesn't necessarily guaranty UV protection.
Glare: A Problem Affecting Your Comfort, Performance, and Safety
In sunny weather, alpine or downhill skiers spend most of their time exposed to direct sunlight. You can't count on tree cover because most downhill ski centers will not have trees on their runs either because of their altitude or by design. Downhill skiing among trees is too dangerous and most ski centers prefer not to expose their customers to the risk. The blinding white glare of a ski slope gets in the way of seeing snow texture, bumps, and other skiers.
On the other hand, the exposure to glare is reduced somewhat in cross-country skiing and snowshoeing because of tree cover. But this will depend on where you do these activities. Note that a forest of deciduous trees won't have any foliage to provide cover from sunlight.
Nike prescription glasses are available with polarized lenses and transition lenses that block glare. Polarized lenses provide excellent clarity in bright sunlight by blocking horizontally polarized light. You will encounter horizontally polarized light whether looking across snow on level ground or down a ski slope. Transition lenses adjust their tint according to the amount of sunlight. This allows you to ski under different lighting conditions with a single set of lenses.
Wind and Snow Reduce Your Comfort, Stamina, and Performance
Sunny weather, no wind, and temperatures around 32 degrees Fahrenheit are ideal for downhill and cross-country skiing as well as snowshoeing.
Provided you don't take many falls, there's no reason a pair of sunglasses with proper UV and glare protection won't suffice.
However, if it's snowing, windy, very cold, or you're likely to take a lot of falls in powdery snow, you will need protection from wind and snow getting between your glasses and your face. Windy conditions or high-speed downhill skiing in very cold temperatures can dry out your eyes if your tear ducts can't keep up with the moisture loss. On the other hand, if your eyes tear excessively, then the tears will make your vision blurry.
Nike prescription glasses such as the Wiley X XL-1 Advanced, Matte Black address these issues with its No Tears™ system for sun, sand, snow, and wind protection. It has a removable foam gasket as well as an elastic strap to hold it in place no matter how aggressively you ski. It also has changeable lenses for adjusting to different lighting conditions. Other Nike prescription glasses models with similar features are also
available.
If you wear prescription glasses, there's no reason you must settle for wearing giant goggles over them when engaging in winter sports. Besides aesthetic considerations, another problem with this arrangement is that your prescription glasses aren't designed to stay put during aggressive activity or when taking falls. Nike prescription glasses for winter sports both correct your vision and provide the protection discussed above.
