Ski goggles
A goggle is a spectacle that the skiing is used for protection from the sun as well as protection against whirled snow. The reflection of the sun by the snow at high altitudes blinds the human eye. Extreme mountaineers also wear comparable glasses to prevent snow blindness . The term snowboard goggles is used synonymously.
Types and equipment
There are two types of ski goggles or glasses that are used for skiing: so-called ski goggles (ski goggles that cover a large part of the face) and regular sun or sports glasses (usually equipped with a rubber band for better grip). In addition to the tasks mentioned above, newer ski goggles have the property that they (through colored lenses) improve vision in fog. Often the modern glasses (especially the ski goggles) are also fog-free.
For people who wear glasses
People who wear glasses who want to go skiing or snowboarding need different ski goggles for these activities than people without visual impairment.
Over the Glasses - OTG
On the one hand, there are the glasses over the glasses, whereby the ski goggles rest over your own corrective glasses. The term “Over the Glasses” is common for these ski goggles. OTG for short. The glasses are larger than normal ski goggles, as they have different cutouts that serve the comfort of the wearer and the safety of the corrective glasses. The recesses are located inside the nasal cavity and can also be found in the ear area on the sides. These recesses are padded with foam or silicone for better carrying. The glasses often fog up quickly because the air cushion that is present quickly causes changes in heat.
Prescription ski goggles
The lenses for the ski goggles are adapted to your own eyesight by the optician and ground accordingly. However, this service is not covered by the health insurance.
Ski goggles with clip mechanism
With this type of glasses, only the glasses (clips) are changed. Depending on the frame model and manufacturer, clips can be pushed into a slot provided for this purpose or they are attached magnetically. So not only clips with prescription can be changed. It is also possible to adapt the lenses to the different weather conditions.
Folding visor on the ski helmet
This ski helmet has a fold-down visor. The corrective glasses remain under the visor and thus protected. Most ski helmets are not closed at the neck area.

Filter category
The blue tenuators have established themselves as common color filters. They weaken the high blue component of the light, which results in a gain in contrast. In practice, five categories have prevailed for the transparency of the tint. Visible light transmission (VLT) is used as the unit .
- 80 to 100% VLT: Category 0 (heavy cloud cover and floodlights and when it starts to get dark)
- 43 to 80% VLT: Category 1 (changing conditions)
- 18 to 43% VLT: Category 2 (partly cloudy and sunny days)
- 8 to 18% VLT: Category 3 (mostly sunshine)
- 3 to 8% VLT: Category 4 (sunshine)
Shape and property
A spherical disk shape is mostly used. The discs are modeled on the shape of the eyes, which prevents distortions and relieves the eyes. Some models offer double lenses , mirrored specimens, polarized lenses and other equipment details. So-called anti - fog coatings prevent fogging on the inside of the glasses and ventilation technology regulates the exchange of air.
