Building the perfect goggle setup is all about matching your lens to the weather, and understanding VLT makes that choice incredibly easy. VLT stands for Visible Light Transmission. In super simple terms, it is the percentage of ambient light that a lens lets pass through to your eyes. Think of it like the tint on a car window:
- High VLT 50% to 85%: Lets a lot of light in. You want a high VLT on dark, cloudy, or snowy days so your vision is brightened and you can see the terrain clearly.
- Low VLT 5% to 20%: Blocks most of the light. You want a low VLT on bright, sunny bluebird days so you do not have to squint and your eyes stay relaxed.
The easiest rule of thumb to remember is this: Dark out? High VLT. Bright out? Low VLT.
We know that replacing your gear can sometimes be a headache. Many goggle brands make you go on a wild goose chase just to figure out which lens fits your frame, and once you finally find it, the price can easily be $120 or more. BOLD has made a commitment to always have replacement lenses available for our goggles at a highly affordable price. We have also made the entire process super easy. We mark the model name directly on the lens itself, along with a clear label indicating if it is a sunny day lens or a low light lens. You will always know exactly what you are riding with and exactly what to order when it is time for a fresh one.
To make finding your perfect lens as simple as possible, here is a quick guide to our BOLD lens colors, their exact VLT percentages, and the ideal weather conditions for each:
Sunny Day Lenses Designed for bright bluebird days with harsh glare and zero clouds.
Everyday Lenses Highly versatile options perfect for mixed conditions, partial sun, and shifting clouds.
Low Light and Stormy Day Lenses Powered by our POW Viz Plus high contrast technology, these are perfect for flat light, active snowfall, and heavy overcast skies.
Night and Extreme Low Light Maximum visibility and light transmission for night skiing under the stadium lights or navigating severe blizzards.
Photochromic Auto Tint Lenses The ultimate one lens solution. This smart technology automatically darkens in the sun and lightens in the shade.
Swapping your lenses to match the exact environment is the best way to get the most out of your time on the mountain, no matter what the Steamboat weather throws at you.
Shop by Condition
Light conditions on the mountain change constantly. Having the right VLT (Visible Light Transmission) in your goggle is the difference between seeing the terrain and guessing at it.
- Stormy Day / Low Light Lenses — High VLT (50–80%). Built for overcast skies, flat light, and trees. Arctic Glow is the go-to choice for days when depth perception suffers.
- Sunny Day / Everyday Lenses — Mid to low VLT (15–30%). Rose Silver, Citrus Blaze, and tinted options for bluebird days and high-altitude glare.
- Clear Lenses — 90%+ VLT. Night skiing and extreme low-light conditions where you need maximum light transmission.
- Photochromic Auto-Tint Lenses — One lens that adjusts automatically as UV changes throughout the day. No swapping required.

BOLD lenses are frame-specific. The Morningside and Rambler use different shapes and magnetic seats — they won't cross-fit. Find your frame to see compatible lenses:
Frequently Asked Questions
Are BOLD ski goggle lenses interchangeable between frames?
No. Lenses are frame-specific. The Morningside, Morningside Max, Morningside XS, and Rambler each use a different lens shape and magnetic seat geometry. Always match the lens model to your goggle frame. If you're not sure which frame you have, check the inside of your goggle — the model name is printed on the frame.
How fast does the magnetic lens swap actually work?
Under five seconds with gloves on. The lens drops into the magnetic seat, clicks into place along the top rail, and locks. To remove it, press the bottom of the lens and pull — it releases in one clean motion. No tools, no brittle clips, no needing to take off your gloves in cold weather.
What VLT should I use for flat light?
Flat light requires high VLT — 50% or above. BOLD's Arctic Glow lenses are built specifically for this. On overcast and stormy days, a high-VLT lens dramatically improves terrain definition versus a mid-tint everyday lens. See the ski goggle lens guide for full condition-by-condition VLT recommendations.
Can I buy just a lens, or do I need to buy a full goggle package?
Just the lens. Every product on this page is a standalone replacement lens — no frame included. All ship free and snap into your existing BOLD goggle in seconds. If you don't own a BOLD goggle yet, complete packages starting at $179 with two lenses and a hard case are available in the ski goggle collection.
