What Is Suntech?

HI-Q Suntech, lenses that are clear indoors and darken when exposed to sunlight — offer a convenient way to protect your eyes outdoors from UV rays and bright light without having to carry around a pair of sunglasses.

The molecules responsible for causing Suntech lenses to darken are activated by the sun’s ultraviolet radiation. Because UV rays penetrate clouds, Suntech lenses will darken on overcast days as well as sunny days.

Suntech lenses typically will not darken inside a vehicle because the windshield glass blocks most UV rays. An added benefit of Suntech lenses is that they shield your eyes from 100 percent of the sun’s harmful UVA and UVB rays.

Because a person’s lifetime exposure to sunlight and UV radiation has been associated with cataracts later in life, it’s a good idea to consider suntech lenses for children’s eye wear as well as for eyeglasses for adults.
