Characteristics:
1. Protection from Cold Wind: Ski goggles prevent cold wind from irritating the eyes.
2. UV Protection: They shield the eyes from harmful UV rays.
3. Anti-Fog: The lenses are designed to resist fogging.
4. Safety on Impact: In case of a fall, ski goggles should not cause injury to the face.
Functions:
1. Protection from Cold Wind: Prevents cold wind from irritating the eyes.
2. UV Protection: Shields the eyes from UV radiation.
3. Anti-Fogging: The inner lens should not fog up.
4. Safety on Impact: Ski goggles should not harm the face in case of a fall. (Note: Skiers who wear glasses should choose OTG (Over The Glasses) goggles to fully cover their prescription eyewear.)
5. Impact Resistance: The lenses should meet international standards, passing drop ball tests and impact resistance tests. With technological advancements, ski lenses have transitioned from single-layer to double-layer designs, becoming fog-resistant and adaptable to various weather conditions. The lens structure consists of an inner lens and an outer lens. The inner lens is made from resin material, which has good water absorption properties and excellent anti-fog capabilities when treated with anti-fog solutions. The outer lens has a hardened surface to prevent scratches, with a color coating applied on top, primarily made from silica and titanium dioxide. Additionally, the top edge of the frame features breathable vents made from sponge material, allowing the heat from the face to escape, ensuring optimal visibility through the goggles.
