In low light, Photochromic Transitions® Lenses take on a green/ yellow color which provides high contrast and is designed to minimize glare and maximize useful light information reaching the eye. In bright daylight (behind the windshield of a car) they change to a copper color which reduces glare and excess visual light and provides good traffic signal recognition, highlighting reds and greens. Finally, in sunny outdoor conditions, they become a dark reddish-brown color, providing maximum comfort in high light conditions by filtering excess light so that the eye does not become saturated. And because the lens is “Activated by Transitions®”, it offers 100% protection against UVA and UVB rays. In most of daylight driving situations, Photochromic Transitions® Lenses provide optimal visual comfort and safety.
Photochromic Transitions® Lenses transition from clear to dark in the presence of ultraviolet light, and block 100% of harmful UV rays. Innovative photochromic technologies have produced unparalleled lens performance in nearly every lens design and material, including shatter-resistant lenses, bifocals, trifocals, progressives, and standard and high index materials. Transitions® Lenses are also perfect choices for Children’s Eyeglasses.
Transitions® Lenses begin to darken the moment they are exposed to UV light. The greater the intensity of UV rays, the darker the lenses become. The moment UV rays are no longer present, the lenses begin to fade back. In short, Transitions® Lenses quickly darken when you go outdoors, and fade back fast when you return indoors. Most wearers report that the adjustment happens so smoothly, they are unaware of it.
Transitions® VI also has expanded protection at the UV end of the spectrum. Previous Transitions® Lenses blocked UVA (290 to 315nm) and UVB (315 to 380nm), but Transitions® VI has expanded protection up to 400nm.
Transitions® Lenses contain special photochromic dyes that cause the lens to activate, or darken, when exposed to ultraviolet rays from sunlight. When the UV light diminishes, the lenses fade back. As light conditions change, the level of tint adjusts, offering the right tint at the right time. It’s important to note that the UV blockage remains constant. Transitions® Lenses provide automatic protection from UV rays in both the clear and darkened states.
Everyone who needs protection from glare and UV rays can benefit from Transitions® Lenses. They are appropriate for children, adults and patients with special eyecare needs. The tint level of Transitions® Lenses adjusts quickly as light conditions change to provide convenient protection from glare and 100% blockage of harmful UV rays.
Children: It’s never too early to start caring for your children’s eyes. Children are excellent candidates for Transitions® Lenses. It is estimated that 80% of total lifetime exposure to UV rays occurs before age 18. Children are more susceptible to UV radiation because their eyes continue to develop into the teen years.
Driving: Windshields in today’s vehicles block most of the UV rays that cause Transitions® Lenses to activate, or darken. As a result, when worn inside a car where less UV light is present, the ability of the lenses to transition to dark is reduced.
A new category of lenses, DriveWear®, Activated by Transitions®, has stepped in with a unique, high tech solution for driving. DriveWear® lenses combine the glare protection of polarized prescription sunglasses and photochromics which respond to both visible and UV light . The result is a lens that can sense the light coming in from outside of the car and transition to dark accordingly. Drivewear® lenses are capable of sensing and reacting to varying light conditions both outside and behind the windshield of the car. From bright sunlight accompanied by intense, blinding glare, to overcast inclement conditions, Drivewear® lenses provide the ideal visual solution.
Special Needs: Certain people develop a heightened sensitivity to light, known as photosensitivity, and are more susceptible to visible light. Photosensitivity can develop with conditions, such as diabetes or recent eye surgery. The condition can also be caused by taking certain prescription medications. Some medications, even those used to treat conditions not related to vision, can cause the eyes to be more susceptible to damage from UV rays. Patients with special needs are excellent candidates for Transitions® Lenses.
