New Transitions® GEN S™ lenses

Transitions Optical’s latest technological revolution is now available! Transitions GEN S has three core performance pillars which are redefining wearers’ eyewear experience.

GEN SPEED™: Ultra-responsive to light1

Fully clear indoors and darkens in seconds outdoors2. When fully activated, the lens is as dark as a sun lens outdoors2 and fades back when returning indoors is around 2 minutes³.

GEN SMART™: Effortless vision experience

Offers better visual performance, faster, to ensure a continuous visual experience in harmony with varied and changing light environments⁴. Thanks to its responsiveness to light, during fade back there is 40% faster vision recovery⁵ and 39.5% improved contrast sensitivity⁵ vs Transitions® GEN 8™.

GEN STYLE™: Spectacular colour palette

Available in 8 exclusive colours, including the brand-new colour Ruby. The range of lens colours provide endless styling possibilities for wearers to express themselves when pairing frames and lens colours.
