Polarized Vision: The Physics of Everest Eyewear

Blocking 99% of UV on a Mount Everest Expedition

The Light That Blinds

The Mount Everest summit is one of the brightest places on Earth. Without specialized eyewear, the combination of high altitude and snow reflection will cause permanent eye damage during your Mount Everest expedition.

Visible Light Transmission (VLT)

Regular sunglasses allow too much light in. For the Mount Everest summit push, you need VLT levels as low as 5%. These lenses are so dark they can only be used in the intense glare of a high-altitude expedition.

The Polarization Filter

Polarized lenses block the horizontal waves of light reflecting off the glacier. This allows Everest trekking groups to see the texture of the ice and spot hidden crevasses that would otherwise be invisible.

Anti-Fog Engineering

When using an oxygen mask, your breath can fog up your goggles instantly. Professional Mount Everest expedition goggles use double lenses and specialized vents to maintain clarity during the summit ridge climb.

Protect Your Sight

You cannot climb what you cannot see. Invest in the best Category 4 eyewear to ensure you reach the Mount Everest summit with your vision intact.
