Abstract

The invention relates to a vision protecting instrument with interpupillary distance adjustment and double optical path focusing, belonging to the technical field of medical appliances. The invention has the technical scheme that the vision protecting instrument with interpupillary distance adjustment and double optical path focusing comprises a base, a stabilized voltage supply, a box body, a double optical path focusing optical system, an interpupillary distance adjusting mechanism, a support plate, an electric control panel, a film operation panel and the like, wherein the box body is installed on the base, the stabilized voltage supply is fixed on the box body, the box body and the support plate are integrated; two fixing blocks in the interpupillary distance adjusting mechanism are fixedly connected below the support plate; under the interpupillary distance adjusting mechanism, an interpupillary distance adjusting block is fixedly connected with two lens barrels in the double optical path focusing optical system, so that the optical axes of the lens barrels are parallel to the interpupillary distance adjusting block; the electric control panel is installed on the inner wall of the top cover of the box body; and the film operation panel is installed on the upper surface of the top cover of the box body. The vision protecting instrument integrates the interpupillary distance adjusting mechanism and the double optical path focusing mechanism and has a simple structure.

Description

technical field [0001] The invention belongs to the field of medical device technology and relates to a visual eye protection instrument with pupil distance adjustment and dual optical path focusing. Background technique [0002] It is understood that the number of primary and middle school students and children with low vision is increasing, and the number of students with false myopia and true and false mixed myopia is also large, and myopic amblyopia has increased. Irregularity, watching TV, playing computer for too long, and excessive use of the eyes cause spasm of the eye-adjusting muscles. The visual eye protection instrument of the present invention has significant effects on treating pseudomyopia, hyperopia, amblyopia and myopic amblyopia, especially preventing myopia, amblyopia and low vision of primary and middle school students and young children. [0003] Among the existing technologies, we have not found the closest prior art to the present invention after sear...
