Interest in performance-oriented sunglasses has surged in recent years, along with participation in outdoor activities such as mountain biking, snowboarding, rock climbing, kayaking, skiing, golfing and in-line skating. Durable and specialized performance sunglasses also are recommended if you work outdoors, do a lot of driving, or you are in the military.
To meet the demands of both casual and competitive athletes, sunglass manufacturers are developing innovative new sport sunglasses to provide the best vision possible under extreme conditions.
The results: lightweight, flexible, durable materials, no-slip components that do not fail in the heat of the moment and, of course, many choices in lenses.
Sunglass Lenses For High Performance
Perhaps the most important elements of effective sports sunglasses are the optical quality and visual enhancement properties of the lenses. Many lens tints such as brown, green, gray, yellow and orange are now available, with each color suitable for specific circumstances.
Polycarbonate lenses are the best choice for high performance sunglasses because they are lightweight, super strong and more impact-resistant than most other lens materials.
Polarized lenses also are in demand because they reduce glare from light reflecting off flat surfaces, such as water or a field of snow.
Though glass lenses have the best optical quality of conventionally produced lenses, they are not recommended for rugged activities because they are more likely to shatter on impact than lenses made of polycarbonate or other materials.
For the best possible vision, comfort and clarity in changing light conditions, consider photochromic lenses. These lenses are clear indoors and at night, and darken automatically in sunlight. They’re available in a variety of sun-activated tints, including contrast-enhancing brown, neutral gray and soothing green.
Regardless what type of sports sun lenses you choose, have anti-reflective coating applied to the back surface of the lenses — this will eliminate glare from light reflecting off the back of your lenses when the sun is behind you.
What Kind Of Sunglass Performance Do You Need Outdoors?
Each outdoor activity has its own specific visual requirements, and this has led to the development of sports-specific sunwear. Many frames and lenses also now specifically target the golfer, cyclist, boater, rock climber, etc.
For example, a certain lens tint may help golfers notice subtle changes in the direction of the blades of grass on a green that could affect the line of a putt. But a completely different tint may be best to help a hunter see the contrast of a bird against an overcast sky.
