What is vlt in ski goggles?

VLT, or Visible Light Transmission, is a measurement of how much light can pass through the lens of ski goggles. The higher the VLT percentage, the more light that can pass through the lens, making them ideal for low-light or overcast conditions. Conversely, a lower VLT percentage means less light can pass through the lens, making them better for bright, sunny days.

Different VLT percentages are suited for different weather conditions. For example, goggles with a VLT of 0-20% are best for bright, sunny days, while goggles with a VLT of 20-50% are better for overcast or cloudy conditions. Goggles with a VLT of 50% or higher are ideal for low-light or nighttime skiing.

It is important to choose ski goggles with an appropriate VLT percentage for the conditions you will be skiing in to ensure optimal visibility and eye protection. Many goggles come with interchangeable lenses, allowing you to switch out lenses with different VLT percentages based on the weather conditions.
