Light under control

What sets Transitions® lenses apart

LIGHT INTELLIGENT TECHNOLOGY

Each of the Transitions lenses has a unique formula of adaptive lens technology. Made up of trillions of photochromic molecules, these patented formulas are integrated into the surface of the lens and constantly recalibrate, so the optimal amount of light reaches your eyes whether you’re indoors or outdoors.

How Transitions adaptive lenses work

Our innovative adaptive lenses adjust to changing light conditions, both indoors and out. See how they work.

This is for demonstration purposes only.

CHROMEA7™ TECHNOLOGY

Our Chromea7 technology, featured in Transitions® Signature® lenses, is an advanced formulation that allows lenses to be more responsive in outdoor lighting conditions across all temperatures. Chromea7 allows Transitions Signature lenses to be especially reactive to indirect sunlight and hot temperatures, so it's darker when it matters most. Watch the demo to see how it works.

PLoS ONE 8(8): e71398. doi:10.1371/journal.pone.0071398 (August 23, 2013). Identified Harmful Blue Light through in vitro experiment on swine retinal cells, where the most toxic wavelengths are high energy visible light falling between 415-455nm on the light spectrum (blue-violet light).
