Choosing the right ski goggles is very crucial in terms of safety and performance improvement. VLT, or in its full expression, Visible Light Transmission, impacts your visibility in different weather conditions. 

In this article, Yoziss will explain what the visible transmission percentage means in ski goggles, how VLT relates to lens tints, and how to choose the perfect goggles that fit your needs.

What is VLT in Ski Goggles? Visible Light Transmission Meaning

1. What is VLT?

VLT means Visible Light Transmission, and its measurement unit is the percentage (%). It tells you how much visible light passes through the lens of your ski goggles and thus directly influences what you see and how comfortable the vision feels in different conditions. For example:

A high VLT percentage, such as 80-100%, has more light passed through and is best for low-light conditions, cloudy or snowy days. A low VLT percentage, like 3-8%, blocks more light and is meant for bright, sunny days.

2. Different VLT Categories/Levels

The visible light transmission percentage is generally categorized into 5 levels, from S0 to S4, among which "S" stands for snow.

· S0 (80%-100%): Best for nighttime skiing or extremely overcast conditions where maximum visibility is required.

· S1 (43%-80%): Suitable for cloudy or foggy conditions, providing enhanced visibility in low light.  

· S2 (18%-43%): An all-purpose option, ideal for skiing in partially cloudy to moderate light conditions.  

· S3 (8%-18%): Designed for bright, sunny days, these lenses significantly reduce glare and eyestrain.

· S4 (3%-8%): Perfect for extremely bright, high-altitude environments where glare is intense.

3. What's the Best VLT Category?

The ideal VLT category depends on the conditions in which you'll be skiing:

For overcast or low-light days, opt for S1 to S2 lenses.

For sunny, cloudless days, S3 to S4 lenses will be a better choice.

Finally, an all-purpose lens in the S2 range can handle most of the lighting conditions for casual skiers.

How Does Tint Color Relate to VLT?

Lens tint color has a very crucial role in determining how VLT will affect your performance. Generally, the lower the visible light transmission percentage is, the darker the lens color will be (less light will reach your eyes). In contrast, the higher the visible light transmission percentage is, the lighter the lens color will be.

For instance, S0 lenses usually come with transparent or considerably light tints; S2 lenses are often with medium tints; S4 lenses can have very dark tints.

How to Choose the Right Ski Goggles

1. Consider Your Skiing Environment

Select a VLT level based on your typical skiing conditions:

Low light or night skiing? Try to go for high VLT, such as S0-S1 lenses.

Bright, sunny slopes? Choose low VLT lenses from S3 to S4.

Variable conditions call for a mid-range S2 lens that's good as an all-around performer.

2. Lens Technology and Additional Features

Some of the technologies worth noting when picking out goggles include:

· Anti-fog Coating: Prevents your lens from fogging up, keeping your vision free. 

· Polarized Lenses: These lenses cut the glare for much better visibility in super bright conditions. 

· Interchangeable Lenses: Allow changing lenses quickly depending on weather and light.

3. Design and Style

Comfort and fit are just as important as functionality. Features to look for include the following:

· Adjustable Straps to fit helmets in different sizes snugly. 

· OTG (Over-The-Glasses) Design for glass wearers. 

· Durable Frames and Padding for long-time comfort. 

· Fashion design for a personal style statement.
