Do polarized lenses reduce the risk of snow blindness?

What Causes Snow Blindness

Snow blindness occurs when the cornea is exposed to intense, reflected light from snow and ice. This is often due to the high concentration of salt and water in snow, which acts as a mirror to reflect and amplify the sun’s rays. In extreme cases, this can cause permanent damage to the eyes.

Prevention and Treatment

To prevent snow blindness, use sunglasses or goggles with UV protection and a polarized lens when spending prolonged periods in snowy environments. The American Academy of Ophthalmology recommends sunglasses with a minimum of 99% UV protection and a light transmission of 18% or less. When experiencing snow blindness symptoms, such as eye pain, sensitivity to light, and blurred vision, seek medical attention immediately.

Choosing the Right Goggles

When selecting goggles for snow sports, look for those with a wrap-around design to minimize peripheral glare. Consider goggles with interchangeable lenses, allowing you to switch to a polarized lens in high-glare conditions. For optimal protection, choose goggles with a frame made from a durable, impact-resistant material, such as polycarbonate or Trilite.
