I work for Transitions Optical and really appreciate everybody’s comments on their experience with Transitions lenses. The great thing about the technology is that it is constantly changing and advancing every day. We’ve heard great things from hikers in the past that have used our products like Dr. Ed Eberhart, a retired eyecare professional, who wears Transitions lenses to hike across the most scenic trails in the world. We also have a variety of lens options that work to meet the different needs of different lifestyles, including photochromic sun wear as well as everyday lenses, including XTRActive Transitions lenses that do activate behind the windshield. Check out the lenses section on our website (transitions.com) for more information.
There were also a couple of comments made that I wanted to mention a few things on. Transitions lenses are activated by UV light. As the amount of UV light changes—because of clouds, hats or windshields—the lens adjust darkness. Unlike a clear lens, clip on or fixed tint lens, the lens adjusts so your eyes don’t have to; this reduces eyestrain and fatigue especially in conditions where the amount of light present is constantly changing; however, there are times when sunglasses are definitely recommended over Transitions lenses. It is also because of the need to have UV light present that original Transitions lenses do not activate behind the windshield or at night. In a non-activated state, Transitions brand lenses are as clear as an ordinary lens and should not interfere with vision at night or driving. If you do choose to purchase Transitions lenses, please ask your eyecare professional for a Certificate of Authenticity to prove that the lenses are Transitions brand lens. Hope this is helpful to you in making a decision.
