About Transitions Lenses
Transitions lenses help you see better today and tomorrow.
Transitions lenses are variable tint lenses.Indoors and at night, Transitions lenses stay clear as regular clear lenses.
Outdoors, in the suns UV rays, they change tint to sunglass dark* in bright sunlight, reducing glare to help you see better. Transitions lenses also reduce eye fatigue as they constantly even out light variations. Your eyes will feel more comfortable all day long.
In addition, they block 100% of harmful UVA and UVB rays, helping to preserve your long-term eye health.
Convenient? Transitions lenses automatically change tint as outdoor light conditions change, so you dont have to change spectacles. The ideal choice for everyday.
*Photochromic performance is influenced by temperature, UV exposure and lens material. Please note that transitions lenses require UV exposure to initiate the conversion process and may therefore not work whilst driving if your car has UV reflective windows.
How do Transitions lenses work?
Transitions lenses contain patented photochromic dyes which activate or darken the lens 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 the right level of tint and allowing just the right amount of light to reach the eye. This action allows Transitions lenses to help protect your eyes from the light you can see reducing glare, diminishing eye strain and fatigue. This enables you to distinguish contrast more easily.
For the light you cant see ultraviolet light Transitions lenses can help protect your eyes for long-term preservation of healthy sight. Its 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 cant see while you enjoy comfort and vision quality in the light that you can see.
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. However they remain aware of the visual comfort the lenses continue to provide in any light.
Transitions lenses are compatible with virtually all frame styles, including the latest fashion frames. And theyre 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 no-line progressive lenses. Ask your optician for advice.
Transitions lenses are the first lenses to receive the World Council of Optometry (WCO) Global Seal of Acceptance for Ultraviolet Absorbers and Blockers based on the WCOs 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.
