3rd year: Ski goggles Lens research

Ski Goggles Components



The are two different basic shapes that goggles lenses can have. Flat lenses are flat vertically with a curve sideways across the goggles. Flat lenses are the cheaper type of lens, and are good for people on a budget. Spherical lenses are curve in all directions, and are shaped as if they were cut from part of a sphere. Spherical lens are more expensive, but offer better peripheral vision, and have less optical distortion.

Lense tint

The lens tint is the colour used to darken what you see when you look through a lens. Once you have been wearing a pair of goggles for a few minutes you generally won’t notice the tint any more, but its effects are still there. Different lens tints are better for different weather conditions, some colours make it easier to see definition in the snow when it’s low or flat light, and other colours are better at reducing glare from the snow when it’s sunny. Lenses that are good in low light generally have a lighter tint and a higher VLT (visible light transmission), whereas lenses that are better in strong sunlight generally have a darker tint and lower VLT. On most goggles the lens can be changed easily, so if money is not such an object or you are a very keen skier, you might have a different lens for each weather condition. Below is a rough guide to lens tints for different conditions:

  • Overcast / Snowing – Yellow, Rose
  • Sunny – Orange, Gold, Blue, Grey
  • Allround – Amber, Rose
  • Night Skiing – Clear


Reflective coating

Many goggles have reflective coating on the outside of the lens that creates a mirrored effect. This type of lens is generally good for sunny weather as the reflective layer reduces glare from the snow. The colour of this mirror effect is not necessarily the colour of the lens tint though, as the coating applied on the outside of the lens works differently to the colour of the material that the lens is made from.

UV protection

Virtually all ski goggle lenses these days protect you 100% from UV light, making sure harmful UVA, UVB, and UVC rays cannot get to your eyes.
