Essilor Crizal® Prevencia® 1.50 Optical Lenses

Essilor Crizal® Prevencia® 1.50 are optical lenses with a 1.50 refractive index and Essilor's advanced Crizal® Prevencia® coating, designed to provide clear vision, anti-reflective protection and selective blue-violet light filtering.

Crizal® Prevencia® is a specialised Essilor technology that selectively filters part of the blue-violet light spectrum while allowing essential blue-turquoise light to pass through.

According to Essilor, Crizal® Prevencia® coating filters 20% of blue-violet light between 400 and 455 nm, providing selective filtering rather than indiscriminately blocking the entire blue light spectrum.

Blue light is present both in the natural environment and in everyday life, with the sun being its most powerful source. Blue light is also emitted by artificial lighting and digital devices.

At the same time, Crizal® anti-reflective technology helps reduce distracting reflections on the lens surface, contributing to improved transparency and clearer everyday vision.

The 1.50 refractive index is a classic choice for prescription eyewear and is suitable for prescriptions where a higher refractive index for increased lens thinning is not required.
