All ESS lenses filter 100% of harmful UVA/UVB rays. Even ESS clear lenses offer 100% UVA/UVB protection. UVC rays are filtered by the outer atmosphere and do not reach the Earth's surface.
Polarized lenses reduce glare from reflective surfaces. Light travels in wave- form, arriving at our eyes in a spectrum of vibrations occurring in both vertical and horizontal axes. Most reflected visible light--such as the blinding glare associated with water, snow, pavement, automobile glass, etc.--travels in a horizontal direction.
Safety-rated ESS Polarized lenses contain undetectable, vertically-aligned filters that cancel out--via inference patter--these horizontal waves, dramatically improving your eyesight and reducing eye strain in many environmental conditions. Reflections from windshields diminish, perception of objects beneath water surfaces is improved as glare is reduced, and the harshness of overly-bright skies or landscapes is greatly mitigated.
ESS Polarized lenses are special in that they offer you the full-assurance of an ANSI-Z87.1-2015 safety rating.
Always refer to the product use & instructions card that came with your ESS eye pro, as specific instructions may apply. Gently wipe the lens with your provided ESS microfiber cloth, and/or gently wash with warm water. Never use household cleaning solutions, sprays, alcohol-based products, or solvents.
