3 Flat Light Ski Goggles

You know those days when the light is flat when you’re out on the ski slopes? Annoying, right?  You are cruising down the slopes, and bumps come out of nowhere because you have no way of seeing them.  Gray on gray is hard to discern.

Not been able to see the slopes well can be frustrating, irritating, and even dangerous if you aren’t wearing a proper pair of flat light ski goggles to help overcome the conditions. This particular kind of goggle features special lenses (category 1 and category 2) which allows in more light in than you’ll get from typical ski goggles. Thanks to this awesome feature, they’ll amplify light, enhance contrast, and brighten everything up, allowing you to see the world around you more clearly. Cool, huh?

Skiing a tough slope in flat light is no place to use your basic, entry-level ski goggles.  These are conditions where being able to see a little better could prevent an injury.  We’re here to help you find and choose the best pair of flat light goggles to fit your needs.

Flat Light Ski Goggles Buying Guide

When you’re skiing in low light and snowy conditions, make sure to seek out a pair of specialized goggles sporting category 1 and category 2 lenses. These types of lenses offer much higher light transmission than regular ones and are typically termed ‘flat light’ ski goggles. The products we’re talking about are both perfect for mountain ski slopes and any other places where the light is flat. Makes sense, right?

Category 1 lenses feature 79-46% light transmission, are slightly tinted and highly recommended for skiing in flat or heavily overcast light conditions. Category 2 lenses offer 45-18% light transmission and are moderately tinted and most suitable for bright and brightly overcast conditions.

Type-wise, modern thermal lenses with dual layers are also the most helpful when you are looking to avoid fogging in flat light or otherwise. With their curved shapes and spherical lenses they provide you with enhanced peripheral vision, reduced glare, and less distortion.

Color-wise, flat light ski goggles with yellow, amber or gold lenses are ideal for flat light and snowy days. They are designed to enhance detail, therefore you’ll easily eye bumps and holes in the snow, will help you ski mogul, and spot the rough spots you want to avoid in flat light conditions. As well, they sharpen vision and filter out the snow’s brightness making the experience easier on your eyes. Persimmon or reddish lenses are another way to go, as they can jack up the contrast in flat light and also work well in brighter conditions. Also available are photochromic (or photochromatic) goggles which are able to lighten or darken according to the light conditions. Thus, in flat light they will also help you with accurate detail perception. A lens color to avoid in these conditions is black, as it can seriously impair your vision when it comes to flat light conditions or when skiing at night.

What is Flat Light in Skiing?

Flat light on the slopes is caused by a convergence of light conditions.  It usually happens on a slightly cloudy day or overcast day, one which has some type of filter between the sun and the ground, such as haze, fog, or perhaps light snow.  That is enough to cause less light to come inside your goggles, but still create some illumination of the snow which can give your brain confusion.  The lack of shadows eliminates contrast, which your brain relies on to judge the terrain.  Counterintuitive is the fact that your eyes can often see better when conditions are heavy clouds, causing the snow to be less white and bright.  A day of full sun, of course, is usually the best condition for seeing contrast in the snow.

There is also evidence that the effects are flat-light increase with age, as your eyes lose some of their ability to quickly adjust to conditions.  Medical eye conditions such as cataracts and glaucoma also play a role in making the effects of flat light worse.  However, on certain days, it tends to affect every skier and snowboarder on the entire mountain.

Why Do Cloudy Days Call for Different Ski Goggles?

Downhill skiing is primarily about two things:  Finding your line (where you are going to ski) and then controlling yourself down the mountain.  That second part takes a lifetime to learn, but the “finding your line” part is easier.  However, when clouds create limited contrast on the snow – filtering the sunlight and making it hard to see ice, bumps, or drops – you are at a big disadvantage.

A cloudy day creates the flat light we have been talking about.  A good pair of goggles basically helps you compensate.  While note as good as having great light, the right goggles can help a ton.

What Else Should I Know About Flat Light in Skiing?

Skiing in flat light can be hazardous if you don’t do it right.  All it takes is hitting a mogul that you didn’t see, and you could be airborne or twist a knee badly.

When skiing flat light, take it slower than normal.  This might seem like obvious advice, but we see people going entirely too fast in low-light conditions.  Be sure you have a helmet, no matter how good a skier you are.  Concussions occur quickly, and you want a helmet for those wipeouts.  Finally, perhaps a flat light day is not the right day to tackle that drop or chute that is at the very top of your skill level.  Save it for when conditions are more ideal.

Are Some Goggles Better for Glasses-Wearers?

Yes.  We did an entire piece on OTG ski goggles (OTG = over-the-glasses).  You may want to check it out if you wear glasses while skiing.  The bottom line is that some of these goggles for flat light conditions are also great for those who need to wear their glasses while skiing.
