[0002] A lens is a piece of glass or other one or more curved transparent materials used. When observing things through it, the things appear clear, large or smaller, and it is usually used in glasses, cameras, telescopes, etc. Now there is a lens with an anti-fog patch positioning part. Existing anti-fog lenses only have an anti-fog coating. When a person suddenly enters an environment with a large temperature difference, atomization still occurs. Although the atomization time is short, it still causes trouble to people. Carrying an anti-fog cloth at all times is not convenient; when cleaning the atomized water droplets on the lens surface, the lens may not be cleaned comprehensively, and there will still be local blurring on the lens. And anti-fog sheets applied to helmets are also relatively common, but it is also a problem that it is not convenient to install anti-fog sheets.
