Abstract

The invention provides goggles and a preparation method thereof. The goggles comprise a frame and lenses, wherein the frame is used for supporting the lenses; each lens comprises a substrate as well as at least one of an anti-glare functional film, an anti-infrared three-dimensional photonic crystal film and an anti-laser three-dimensional photonic crystal film which are adhered to the outer surface of the substrate; the lenses are subjected to hardening and anti-fog deep processing. The individual tactical goggles integrating multiple functions are obtained and have the functional characteristics of being high in structure strength, preventing secondary damage by fragment ejection, preventing glare, infrared and laser and the like, and individual combat power is effectively improved.

Description

technical field [0001] The invention relates to goggles and a preparation method thereof. Background technique [0002] 90% of human information comes from the eyes. In combat and training, the eyes are affected by harsh conditions such as strong sunlight and wind and sand, causing blurred and dizzy vision of combatants. pose a major threat. Eyes are the most fragile tissues in the human body. Once they are injured by fragments on the battlefield, soldiers basically lose their combat capabilities. Through the examples of modern warfare, individual tactical goggles have played an important role in protecting soldiers' eyes from damage and improving combat effectiveness in recent modern warfare. For example, as early as World War II, the U.S. military used goggles in the military field, which effectively blocked the damage of strong light and ultraviolet rays to the eyes of pilots, greatly enhanced the clear vision of the human eye under strong light, and improved combat eff...
