Luxottica Quality Sunglasses - Fall & Winter

Even in winter it is importantl to protect your eyes. Cold, dust, sun and snow glare may endanger the health of your eyes.

Wearing quality sunglasses is one of the best protections against these afflictions.

Quality sunglass lenses must:
- block out 99 to 100 percent of both UV-A and UV-B radiation
- screen out 75 to 90 percent of High Energy Visible (HEV) light.
- protect against glare and reflection of the sun to reduce squinting and
  allow the eyes to see clearly
- shield the eyes from wind, dust and pollen
- protect night vision.
  Eyes that are exposed to sun all day have a harder time adjusting
  to darkness at night.
- reduce tearing and squinting.
  The sun's brightness and glare can cause people to squint
  and their eyes to water, making it harder to see clearly.
- keep eyes from becoming dry.
  By blocking the sun's heat, the eye's natural moisture
  does not evaporate.
- provide high-quality optics, free of distortions and
  imperfections and a scratch-resistant surface to maintain vision clarity
- provide anti-fog; anti-glare and anti-reflective coatings
- include lightweight, impact-resistant materials that enhance
  visual contrast that protect against shattering
- come in a variety of colors so you can select the right color
  for your needs

Gray-colored lenses reduce light intensity without altering the color of objects to provide the most natural color vision.

However, brown or amber-colored lenses may be better for those who are visually impaired because they increase contrast as well as reducing light intensity.
