Description

Ski goggles with automatic defogging

technical field

The utility model relates to the technical field of sports glasses, in particular to ski glasses capable of automatically defogging.

Background technique

Ski goggles, also known as snow goggles, are divided into alpine goggles, platform goggles, cross-country goggles, self-curve goggles, etc. Due to the strong reflection of sunlight on the snow and the strong stimulation of the cold wind to the eyes during sliding, the snow environment is easy to cause snow blindness, and it is easy to hurt the eyes when falling during high-speed sports, so ski goggles are needed to protect the skier's eyes.

When skiing, the face emits heat, so ski goggles need to have anti-fog capabilities. The traditional ski goggles use double-layer lenses, the outer lens is impact-resistant and snow-blind, and the inner lens is added with anti-fog material, and the anti-fog effect is achieved through the double-layer lens. However, when the anti-fogging agent of the inner lens fails, the anti-fogging effect cannot be achieved.
