He notes that although polycarbonate lenses are not new, in the last year or so, there have been major technological advances in materials and designs that translate into more benefits for wearers. In short, eyeglass wearers no longer have to give up superior optics and lighter, thinner lenses to get impact-resistance. As a result, polycarbonate lenses are fast becoming one of the most popular choices for all eye glass wearers-for all age groups, active or not. These lenses offer virtually 100 percent UVA and UVB block. Tahran suggests that outdoor enthusiasts discuss tinting and anti- reflective lenses with their eye care professional.
Tints can enhance contrast and minimize color distortion.
Amber is an ideal high-contrast lens for snow sports where sharp definition of the terrain is important. Reflections on ordinary lenses can mean a loss of eight percent of visual transmission. Dr. Tahran also notes that AR lenses can help make the drive back from the ski slopes at dusk or nighttime safer by reducing the glare and distracting double images created by oncoming headlights. Contact lens wearers also should be aware that contacts alone do not provide sufficient protection for most sporting activities. They should also consider wearing protective sports eyeglasses.
