Reference - Lens coating description and chemical resistance
We have developed proprietary coatings to meet the demands of even the most challenging work environments.
From Uvextreme®andUvextreme®Plus anti-fog lens coatings to the anti-scratch coating technology of
Ultra-dura®and Supra-Dura®, our lens coatings ensure longer lens life and enhanced durability*.In addition,
Dura-streme®technology combines the benefits of these industry-leading anti-fog and hardcoats onto one lens.
The chemical resistance chart below will help to determinethe preferred coating for environments where
workers aresubject to chemical exposure.
