Attention skiers, snowboarders, and freestylin enthusiasts! It's important to protect more then just your nose from the sun's powerful ultraviolet (UV) rays! Yes, you've heard this before, but are you aware of the consequences when you disregard the importance of high quality eye protection? A few sunlight-related eye disorders are cataracts (a leading cause of reduced vision in the United States), snow blindness," or photokeratitis (and no, it isn't related to eating too many carrots), a condition caused by excessive exposure of unprotected eyes to ultraviolet light reflected by the snow. This condition can damage the cornea, cause eye pain, extreme sensitivity to light and the sensation of having sand in your eye! Symptoms may not appear until 6-12 hours after exposure. Though the cornea will usually heal with time and treatment, Eye Care Professionals advise taking proper precautions, such as sporting proper eye coverage.
Ultraviolet radiation reaches the eye directly from the sun, and ground surface reflection. According to the World Health Organization (WHO), while UV radiation is generally lower during winter months, snow reflection may double an individual's overall exposure. The WHO advises that fresh snow may reflect as much as 80 percent of UV rays, compared to other surfaces such as, grass, soil and water, which reflect less than 10 percent of UV radiation; dry beach sand (about 15 percent), and sea foam (about 25 percent).
The greatest measure of UV protection is achieved with a combination of UV-absorbing polarized sunglass lenses and a wide brimmed hat. Since most helmets don't come with a wide brim hat, just go with the helmet and full spectrum polarized goggles and that will do the trick! Because sunlight has the potential to reach the eye peripherally from above, below, and around the sunglass frame, be sure to try on glasses that offer the most coverage, either with a wrapping frame, and/or over-sized lenses.
If you're concerned about fog, low visibility, and flat light, and would like to avoid hitting unexpected bumps and getting tossed all around the mountain in front of your friends, and would rather take on any ripple with utmost grace, look for lenses that feature a contrasting color! High quality performance lensesare designed to increase your perception in the environment for which they are worn (I.e. the snow). Performance colors include: yellow, orange, amber, vermillion, brown, rose, and copper. These colors are designed to enhance vision by providing contrast, highlight certain color spectrums, and provide increased depth perception. Neutral colors give you the truest color transmission, which is important for novice drivers because the traffic lights are red, yellow and green! These colors tend to be clear, grey, pumice and green and are not meant to enhance perception, such as with prescriptive everyday glasses that you wear to school. Yes, as much as we'd like to believe performance lenses will improve your academic studies, neutral colors are the recommended option for indoors... with very cool frames, of course.
Lastly, De-Mistyfy Goggle Fogging
Fogging is the predominant complaint with children and goggles. With that in mind please consider these six tips to keep prevent your goggles from fogging.
1. Purchase goggles with: No-fog coatings applied to the inside surface of the lens.
Vents to allow hot, moist air to escape.
And Volume-the larger volume of air inside the goggle, the greater amount of moist air required to create fogging.
2. Don't overdress. This is the # 1 reason goggles fog. If you overdress you will be retaining too much heat and this will vent upwards through the top of your jacket and into the bottom of your goggle through the vents.
3. Provid adequate space between the top of your goggle and your helmet.Air must vent out the top of your goggle when you stop skiing and if the fit is too close, this will not be possible.
4. Dab the water from the lens, do not wipe it. Your goggle lens has a no-fog coating applied to the inside surface. This coating works by absorbing moisture. If you try to wipe the goggle clean with a glove or piece of clothing when it's in this state, you will move the coating around on the surface of the lens, and the lens will appear to be scratched. If you remove it entirely, you will no longer have a viable no-fog coating and fogging will occur with greater frequency.
5. If you fall while skiing and your goggles fill with snow, remove the goggle and shake out all the big clumps of snow. Put it back on and ski to the lift. While you are riding the lift, remove your goggle and place it inside your jacket. The warmth will melt any remaining snow particles and the no-fog will absorb the moisture. When you reach the top of the lift, your goggle should be ready to go. If you must remove water droplets from your goggle, dab the water from the lens, do not wipe it.
6. Monitor the vents on the top of your goggle when skiing on snowy days. As snow accumulates on the top of the vents it decreases the goggle's ability to vent properly. When you stop, hot air rises and goes out the top vent. If this vent is blocked, the likelihood of fogging will increase.
7. Avoid cold goggle start-up. When traveling to the ski area it is important to keep your goggles in a warm place. If you drive to the area with your goggle in the trunk or roof rack, your goggle will be extremely cold on both the inside and outside lens surface. Your face will be 98.6 degrees and your goggle lens will be zero or colder. Put your goggle on and you get instant fogging.
That's it! Happy SNOWSPORTS to all!
