Surpassing sunglass standards for UV
The skin around the eyes and eyelids is often subject to damage from UV light. Continuous exposure to intense sunlight damages not just the skin but the eyes as well. Long-term unfiltered UV radiation can cause permanent eye damage which can result in visual impairment.
Polaroid Eyewear PTX4000 polarizing lenses offer 100% protection against harmful UVA, UVB and UVC rays. They fully meet and regularly surpass official sunglass standards around the world.
We are particularly proud that our PTX4000 polarizing lenses fully meet the higher requirements of the Australian Standard (AS/NZS1067) up to 400nm. The lens has been assigned the highest possible EPF (Eye Protection Factor) of 10 by the Cancer Council Australia.
