Technical Field
The present invention relates generally to the field of protection technology, and in particular to anti-fog protective eyewear.
Background
The protective glasses are protective glasses capable of protecting eyes of a user, and people need to wear the protective glasses in occasions where eyes are required to be protected, so that the eyes are prevented from being injured, such as medical occasions, sports occasions and the like. Antifog is a property that antifog glasses must have for extended wear, otherwise fogging can seriously affect the clarity of the field of view of the wearer.
The present common protective glasses with anti-fog function generally adopt the inner and outer surfaces of the lenses to prevent fog at the same time or the inner surface of the lenses to prevent fog and the outer surface to harden. After wearing for a long time, sweat, water vapor and the like volatilized by a human body are increased continuously, and even if an anti-fog lens is used, a large amount of water vapor is accumulated in a space between the protective glasses and eyes to reach a saturated state, and a layer of water mist can still be formed on the surface of the lens. The antifogging property of the protective glasses is reduced, and the use requirement is not met.
