Abstract
A lens protection structure includes a base, a polyester film, a first silica gel, a second silica gel, and a protective cover. Each of the base, the polyester film, the first silica gel, and the second silica gel defines a through hole for cooperatively receiving a lens. The polyester film is coupled to a surface of the base, and the first silica gel is coupled to a surface of the base opposite the polyester film. The second silica gel is coupled to the polyester film. The protective cover is coupled to the second silica gel and seals a receiving cavity within the base. At least one air escape channel is defined in the base. The at least one air escape channel communicates the receiving cavity of the base to an exterior of the lens protection structure.
