About Transitions® Lenses

80% of consumers know the sun can damage their skin. Less than 10% know it can damage their eyes.

Beyond the controlled environment of your exam room, patients face a world of extreme light conditions that can compromise vision quality and vision health. Transitions lenses have been designed to perform like premium clear lenses indoors and at night that darken to a sunglass-dark tint outdoors. When exposed to ultraviolet light, they rapidly darken, conveniently providing visual comfort, glare reduction and 100-percent blockage of UVA and UVB rays*.

Understanding Transitions Technology

What makes Transitions® lenses work?

Simply put, the performance of Transitions lenses centers around the application of special photochromic dyes to the lens. Molecules that make up that dye appear colorless in the absence of ultraviolet light. However, when exposed to invisible UV light outdoors, the molecules change shape and appear as a color tint. Remove the lens from UV light and molecules quickly revert to their colorless state, appearing and performing like clear lenses.

How do we achieve our renowned lens performance? It's a delicate balance of just the right lens material, patented photochromic dye systems and proprietary manufacturing processes.

Advanced Lens Material

A solid foundation is critical to any successful endeavor. Transitions Optical works hand in hand with top lens manufacturers to formulate lens material foundations, each optimized for photochromic speed, darkness, indoor clarity and service life. This collaboration also ensures excellent processing attributes, coatings compatibility, and ultimate performance quality. The lens material provides a versatile platform that assures Transitions lenses are available for virtually any frame and in nearly every design and material imaginable.

Pioneering Photochromic Dyes

Photochromic dyes enable a lens to change from clear to dark in the presence of UV light. Transitions Optical's exclusive dye packages are formulated to provide true, neutral, predictable and consistent color in their activated states and clarity in their inactivated state. The latest generation of dyes delivers the best speed, fatigue resistance, high-temperature performance and all-around photochromic performance available anywhere. And we should know; Transitions Optical is the acknowledged global leader in photochromic dyes and boasts the only US and European Industrial Representatives to the International Photochromic Scientific Organization.

Proprietary Manufacturing Technologies

The manufacturing process combines the special lens materials and patented dyes using Transitions Optical's proprietary surface technologies. Applying these technologies enables superior indoor clarity and consistent coloration in every Transitions lens, regardless of prescription, material, or design.
