Photochromic lenses automatically darken in response to ultraviolet light outdoors and return toward a lighter state indoors. They provide a convenient option for patients who move frequently between indoor and outdoor settings.
Different products vary in how dark they become, how quickly they change, their available colors, and how much they activate behind a vehicle windshield. Some patients may still prefer a separate pair of polarized sunglasses for driving or prolonged time in bright conditions.
Current Transitions® options include everyday photochromic lenses as well as products designed for greater light sensitivity, polarization, or driving. Availability depends on your prescription, chosen lens material, and the products carried by the practice.
Adaptive sun lenses are also available for selected outdoor activities. These lenses begin with a sunglass tint and adjust within a darker range as outdoor light changes, providing an alternative to sunglasses with one fixed tint.
