To see clearly in snowy terrain, it's important to have the right lens for the occasion. The right lens can make a difference in having a good or bad day on the slopes. Here's a quick guide for recommended lenses in different conditions:
Snowy days have different light than sunny ones. Use a dark lens on bright days to avoid being blinded. For snow days, foggy days, overcast days, and partially cloudy days, use a high-contrast lens like yellow or pink. The right lens makes it easier to see in all weather conditions.
Lighting can be much darker when riding among trees for exemple. If you have a dark lens for bright light, it might be too dark in a dense forest. Later in the day, areas that were in direct sunlight may be shaded. Shaded terrain has flat lighting compared to terrain in bright daylight.
Midday skiing when the sun is strongest requires VLT lenses with low numbers. "Visible Light Transmission" or VLT indicates how much light the lens lets in. Riding in the evening under artificial light requires an almost clear or high VLT lens. Riding in the morning after sunrise and in the evening before sunset requires an medium number VLT lens.
Revo is a coating applied to the outside of the lens. The term 'revo' usually applies when the mirror has more than one color, for example, red-orange or blue-green. While mirror coatings are often chosen for their cosmetic effect, they also reduce glare and increase filtration ability, blocking an additional 10-60% of visible light for increased comfort in intense sunlight. In short, Revo helps eliminate glare in the snow, reduces eye fatigue, and improves contrast.
Photochromic lenses change shade depending on light conditions. They typically start with a light 20-30% shade and darken to 60-80% in strong sunlight. Photochromic glasses have different base tones, and their lenses darken based on their base tone. Photochromic lenses are perfect, for example, when you find yourself in varying environments with different lighting conditions.
We use two different types of lenses in our goggles - cylindrical and spherical. What is the difference between the lenses?
A cylindrical lens is vertically flat and curved on the sides, giving it a low profile. We use this design to create a vintage/retro look on our goggles. Most goggles with cylindrical lenses are designed to sit close to your face and provide a wide field of view.
A spherical lens has a rounded, bubble-like appearance that provides less distortion for the eye. The lens's curve also reduces glare since there are practically no flat spots where light can hit to create glare. Another advantage of a spherical lens is the additional space created inside the goggles due to the rounded shape, helping to further reduce fog. Some spherical lenses even allow you to wear regular glasses underneath, depending on the size of your glasses.
UV400 protection blocks UV rays from reaching your eyes. All Appertiff goggles have UV400 protection that blocks 100% of UV rays. With UV400 protection, UV exposure to your eyes is eliminated, ensuring your eyes are well-protected and not exposed to risks while using our goggles. Using goggles and sunglasses with UV400 protection is strongly recommended by all eye specialists. It is the best protection against the sun's harmful UV rays. If you're wondering whether you'll regret buying a pair of goggles with UV400 protection, the answer is no. You won't regret protecting your vision and avoiding damage to your eyes.
Fog in your goggles can be really annoying and affect your visibility while riding. Here are some tips to prevent fogging and how it works:
Scratches on your goggles can be very annoying and can impair visibility, making the goggles quickly unusable. Here's how you can prevent scratches:
Ski goggles are an investment, and by taking proper care of them, you can extend their lifespan and keep them in good condition for many seasons.

To help show you the differences between our goggle models, we’ve asked Koffe to model them so you can see how they look when worn.
