LENS GUIDE
Knowing what eyewear is best suited for you and your sport can be tricky. Below are a few of the main acronyms, terms, and features that will help guide you through choosing the right VALLONs for you.
DICTIONARY
VLT - Visible Light Transmission.
UVA - Ultraviolet A has a longer wavelength. Associated with skin aging.
UVB - Ultraviolet B has a shorter wavelength. Associated with skin burning
NM - Nanometers.
UV Rays - Ultraviolet rays.
COLORS
Green - Provides contrast by filtering out blue light. Great 'all-rounder' option.
Grey - Great for all-purpose use. Minimizes glare, provides true color perception.
Yellow - Provides greater clarity in fog, haze, and other low-light conditions.
Brown - Great for sunny/partially cloudy conditions. Enhances contrast & depth perception.
Orange - Increases contrast and maximizes optical clarity in low-light conditions.
POLARIZED OR NON-POLARIZED?
Polarized sunglasses block glare from light reflecting off flat surfaces. This means that they're great if you're out on the water.
MIRROR OR NO MIRROR?
An anti-reflective mirror-coated lens is excellent for long days on the mountain or on the water where high levels of sunlight and glare can cause eyestrain.
