Transitions Lenses change from clear to dark, & block 100% of harmful UV rays. Our innovative photochromic technologies have produced an unparalleled lens performance in nearly every lens design and material, including shatter-resistant lenses, bifocals, trifocals, progressives, as well as standard & high index materials available today.
How Transitions Lenses Work
If you wear regular clear lenses, the glare of the sun can cause you to squint and strain your eyes and make it difficult to see objects clearly in bright light. Through advanced technology, Transitions lenses give you the benefits of clear lenses indoors and at night, plus distinct advantages of sunglasses outdoors – all in the convenience of one lens.
Transitions lenses are clear indoors and at night but automatically adjust their level of tint to changing light conditions outdoors. Thanks to advanced technology, they quickly darken when you go outdoors. Step back inside and they quickly fade back to clear. They provide visual comfort and quality at any and every moment, helping you to see better today. And just like sunblock protects your skin, Transitions lenses help preserve the health and wellness of your eyes for the future by blocking 100% of harmful UV rays, so you can see better tomorrow too.
Transitions lenses contain patented photochromic dyes which cause the lens to activate – or darken – when exposed to ultraviolet (UV) rays from sunlight. When the UV light diminishes, the lenses fade back to clear. As outdoor light conditions change, the level of darkness adjusts, creating just the right level of tint and allowing just the right amount of light to enter the eyes at any given time. This action allows Transitions lenses to help protect your eyes from the light you can see – reducing glare, diminishing eye strain and fatigue and enabling you to distinguish contrast more easily.
For the light you can’t see – ultraviolet light – Transitions lenses can help protect your eyes for long-term preservation of healthy sight. It’s important to remember that, no matter how light or dark they appear to be, Transitions lenses are always blocking 100% of eye-damaging UVA and UVB rays. In other words, Transitions lenses provide automatic protection from UV rays in any environment, continually protecting your eyes from the light you can’t see while you enjoy comfort and vision quality in the light that you can see.
Performance you’ll appreciate but may not notice.
Transitions lenses begin to darken the instant they are exposed to UV light. The greater the intensity of the UV rays, the darker the lenses become. The moment UV rays are no longer present the lenses immediately begin to fade back to their clear state. Most wearers report that the adjustment happens so quickly and smoothly, they are unaware of it. But they remain aware of the visual comfort the lenses continue to provide in any light.
Clear indoors. Clearly better everywhere.
Transitions lenses are not just as good as clear lenses, they’re clearly better. Transitions lenses are as clear as regular clear lenses indoors and at night and as dark as most sunglasses outdoors in bright sunlight. Transitions lenses block 100% of eye-damaging UVA and UVB rays and reduce discomforting and disabling glare, providing convenient, automatic protection whether it’s bright and sunny, cloudy, or in between. Unlike regular clear lenses, Transitions lenses adjust quickly as light conditions change to provide the appropriate level of darkness and protection.
Protection is always in style.
Transitions lenses are compatible with virtually all frame styles, including the latest fashion frames. And they’re available in most types of lens materials and designs from plastic to shatter-resistant materials like polycarbonate and Trivex® materials, and from single-vision lenses to bifocals, multi-focals and progressive lenses. With the help of your eyecare professional, you’re sure to find the Transitions lenses that provide the everyday convenient protection, visual quality and visual comfort you are looking for.
A string of very important “firsts”.
Transitions lenses are the first lenses to earn the American Optometric Association (AOA) Seal of Acceptance for UV Absorbers/Blockers and the first to receive the World Council of Optometry (WCO) Global Seal of Acceptance for Ultraviolet Absorbers and Blockers based on the WCO’s scientific testing protocol. Additionally, Transitions lenses meet internationally recognized standards for UV blockage, including ANSI Z80.3, ISO 8980-3, EN 1836 and AS/NZS 1067
