Essilor Transitions® GEN S™ Thin & Lite 1.74 Crizal® Sapphire™ Photochromic Lenses

Essilor Transitions® GEN S™ Thin & Lite 1.74 Crizal® Sapphire™ are premium ultra-high-index photochromic optical lenses combining advanced Transitions® GEN S™ technology, Essilor's exceptionally thin Thin & Lite 1.74 lens material and the advanced Crizal® Sapphire™ anti-reflective coating. They are a premium choice for demanding prescriptions where lens thickness, aesthetics and optical performance are particularly important.

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 as the wearer moves between different lighting environments.

Transitions® GEN S™ technology has been designed with a strong focus on activation and fadeback speed, providing fast response to changing light conditions for a smooth everyday wearing experience.

The ultra-high 1.74 refractive index allows lenses to be made exceptionally thin compared with lower-index materials. Thin & Lite 1.74 is particularly suitable for higher prescriptions where minimising lens thickness is an important aesthetic consideration.

The exceptionally thin construction of Thin & Lite 1.74 contributes to a more discreet and refined appearance, particularly for prescriptions where a lower-index lens would have a noticeably thicker profile.

Crizal® Sapphire™ is one of Essilor's advanced anti-reflective solutions and is designed to provide effective control of unwanted reflections from multiple directions.

The advanced anti-reflective technology of Crizal® Sapphire™ contributes to high lens transparency and reduced visible reflections on the lens surface. When the photochromic lenses are in their clear state, the wearer's eyes remain more visible behind the glasses for a natural and refined appearance.

The advanced Crizal® Sapphire™ surface also helps resist smudges, water and dust, making everyday cleaning and lens care easier.
