Essilor Opti-Fog

Opti-Fog is Essilor's advanced anti-fog lens treatment, designed to keep your vision clear even in the most challenging conditions, from sudden temperature changes to high humidity, exercise, and mask-wearing.

Unlike basic anti-fog sprays that wash off after a few uses, Opti-Fog combines a permanent outer hydrophilic layer with an activator solution (included with the lenses) that must be reapplied periodically to maintain peak performance. When activated, it creates a strong anti-fog effect that lasts significantly longer than standard treatments, keeping lenses fog-free in situations where regular lenses would cloud up instantly.

Ideal for people who move between hot and cold environments, wear masks regularly, or lead active lifestyles, Opti-Fog ensures consistently clear, safe vision without the constant wiping and frustration of foggy glasses.
