Understanding ski goggles

DIN EN 174:2001-07 has been withdrawn. Its successor is DIN EN ISO 18527-1:2023-11, the German version of EN ISO 18527-1:2022. It covers downhill ski and snowboard goggles.

An older EN 174 reference on the model remains the documented original specification. The successor standard does not automatically make it a new certification.

VLT refers to the proportion of visible light transmitted. A lower percentage means a darker lens. The category applies to the lens, not the frame colour.

Oakley’s manufacturer information gives these limits: S0 over 80 to 100%, S1 over 43 to 80%, S2 over 18 to 43%, S3 over 8 to 18% and S4 over 3 to 8%. Use the manufacturer’s category; don’t round limit values into a different category yourself.

Lighter lenses may be suitable in low light, darker ones in strong sunshine. The specific conditions, shade and changing weather all matter. A dark tint alone does not prove UV protection.

An interchangeable lens system lets you fit a suitable lens. Before buying, check whether an additional lens is included and whether it suits your light conditions.

Photochromic lenses change their tint within the range stated by the manufacturer. Response behaviour and temperature play a role. The successor standard specifies additional measurements at 5 °C; this does not provide a changeover time for every model.

Polarisation and photochromic technology are different properties. Polarisation affects certain reflections, while photochromic technology changes the tint. A brand name or general technology description does not prove the specification of your variant.

Try on your helmet and ski goggles together. The goggles should sit evenly without pressure points, and the ventilation channels should remain clear. General brand compatibility is no substitute for trying them on.

OTG means they are designed to be worn over prescription glasses. You’ll need to check whether your frames fit using your own glasses. Compatibility with an optical insert is a different feature.

Children need a suitable frame and strap size. Don’t transfer features from the adult version to the similarly named children’s model.

Ventilation and an anti-fog coating can reduce fogging. They do not guarantee clear vision in every humidity and temperature. Don’t block the ventilation with your helmet or clothing.

Follow the manufacturer’s care instructions. Dry the lens gently and don’t rub a wet inner lens dry. A damaged coating cannot be replaced by a feature name.

Check the manufacturer SKU, lens name, contents and light transmission together. A model family can include fixed and photochromic lenses. Values for a different colour are therefore not evidence.

The selection clearly shows missing details. If a required standard or lens detail is missing, the model is not marked as the Best Choice. Check these points in the shop and the manufacturer’s information before buying.

We only include clearly verified details for the specific model. If the reference is unclear or sources contradict each other, the detail remains open. This prevents a Best Choice label when the value is needed for your answers.
