The 2010 Winter Olympics are upon us.  Lets take a look at the common attributes most Winter Olympians have:

  • Athletic ability
  • Drive and determination
  • Support of family and friends
  • Excellent vision

If you look at all the skiers, snowboarders, speed skaters, lugers and bobsledders, they are all wearing some sort of protective eyewear.  How do they know which lenses to wear?  What if it is cloudy, sunny, snowing, sleeting, raining, foggy, nighttime, or early morning?

snowboardingThink Safety First

You can be certain that the lenses in an athlete’s goggles are made of polycarbonate.  For fast-moving winter sports, this material is much more impact-resistant than glass or conventional plastic. The frame also needs to be lightweight and flexible reducing the likelihood of the lens breaking or popping out in a bad fall.  Prescription lenses can be made for inserts that sit behind the shield of the goggle or some goggles are actually made to wear over a regular pair of eyeglasses.

Think Visual Efficiency Next

Black, gray, or smoke lenses

Best for bright conditions – they dim the bright sunlight to ease the strain on your eyes. Depending on the intensity of the tint, these lenses do darken your vision but gray does not alter color.  These lenses are best for wide-open areas, especially on sunny days.  One should not ski or snowboard in trees or trails with dark lenses.

Amber Lenses
Amber is a color in between a light brown and a dark yellow lens.  Amber blocks blue light, greatly increases contrast.  This color is a good choice for seeing moguls out on the slopes.  Amber is best for under cloudy skies or on dimly lit trails but is not recommended for sunny days.

VSP provider Joel Kestenbaum, O.D. from Long Island N.Y.  provides an overview of dry eye syndrome

Tears bathe our eyes to keep them nourished and usually do not leak down the cheek.  Why is that?  On the other hand, why do tears sometimes flow in such abundance that we must wipe them away?

Various glands in and around the eyelid produce the tears.  Microscopic glands produce the tears that are composed of water, oil, mucous and an abundance of nutrients.  If one of the components of the tears is not produced in the exact amounts, the tears become either too wet or too dry.

A common complaint in my office, especially as people age, is that tears run down the cheek.  Usually excess tear production occurs because the microscopic glands in the lid that produce the normal water part of the tears are not producing enough.  In response, the one large gland, the lacrimal gland, that normally secretes a lot of tears when we cry produces too much water so we drip.  This is classic dry eye syndrome.  Are you confused yet?
