Essilor Transitions® GEN S™ Thin & Lite 1.67 Crizal® Rock™ Photochromic Lenses

Essilor Transitions® GEN S™ Thin & Lite 1.67 Crizal® Rock™ are high-index photochromic optical lenses combining advanced Transitions® GEN S™ technology, Essilor's very thin Thin & Lite 1.67 lens material and the durable Crizal® Rock™ anti-reflective coating.

Transitions® GEN S™ lenses dynamically adapt to changing light conditions. They remain clear indoors and darken when activated by appropriate outdoor light, providing visual comfort throughout changing environments.

Transitions® GEN S™ technology has been developed with a strong focus on activation and fadeback speed, providing fast adaptation as the wearer moves between different light conditions.

The high 1.67 refractive index allows lenses to be made significantly thinner compared with lower-index materials. Thin & Lite 1.67 provides a very thin lens profile and is particularly suitable when greater optical correction is required and lens thickness is an important aesthetic consideration.

The very thin construction of Thin & Lite 1.67 contributes to a more discreet and refined appearance, particularly for prescriptions where a lower-index lens would have a noticeably thicker profile.

Crizal® Rock™ is designed with a strong focus on everyday durability. It provides advanced anti-reflective protection and high scratch resistance, while its advanced surface helps resist smudges, water, dust and particulates.

High-Resistance Technology™ reinforces the durability of the lens surface while helping make everyday cleaning and lens care easier.
