Snow reflects almost 100% of sunlight and is a major source of UV radiation. Overexposure to ultraviolet (UV) radiation can cause permanent damage to the eyes. Without proper eyewear, not only are you increasing your risk of getting an eye sunburn (photokeratitis), but you are also exposing your eyes to the long term side effects of UV radiation, such as cataracts and age-related macular degeneration.
Polarized lenses can offer certain benefits for skiing, but they may not be necessary for everyone.
What is the sadvantage of polarized snow goggles?
Glare Reduction: Polarized lenses are effective at reducing glare caused by sunlight reflecting off snow, ice, or water. This can enhance visibility and reduce eye strain, especially on sunny days or in high alpine environments where glare is more intense.
Enhanced Contrast: Polarized lenses can improve contrast, making it easier to distinguish contours, textures, and changes in terrain. This can be particularly beneficial in flat light conditions or when skiing on uneven surfaces.
What is the disadvantages of Polarized Lenses for Skiing?
Reduced Visibility of Ice Patches: Polarized lenses may make it more challenging to identify subtle variations in the snow, including patches of ice. The polarization filter can diminish the reflection of light from icy surfaces, potentially reducing the ability to spot slick areas. Distortion of Digital Displays: Polarized lenses can interfere with the visibility of certain digital screens or displays, such as ski resort trail maps or some goggles with built-in heads-up displays. The polarization filter may cause distortion or make the screens difficult to read.
How do polarized lenses help to protect the eyes?
Polarized lenses are created differently than regular lenses, due to their ‘sandwich’ design.
A polarized lens contains three layers. The middle layer consists of the polarized material which is stretched into long strands and then laminated between two layers of glass or plastic. This ‘sandwich’ design allows the polarized lens to absorb the reflected light and prevent the harmful UV rays from reaching your eyes.
