Problems solved by technology

[0002] The existing prism-lens combination mirror is a fixed-mode prism and lens, which is not adjustable and has a single purpose
However, although the telescopic mirrors on the existing market can be adjusted, they are still limited to a simple lens without a prism combination, and manual adjustment is not suitable for the vision needs of teenagers in different states such as reading, doing homework, watching TV, and watching computers. Therefore can not effectively prevent and control juvenile myopia

Embodiment Construction

[0024] See Figure 1 ~ Figure 4 , The adjustable prism lens combination myopia controller of the present invention is equipped with a lens adjustment system and a prism adjustment device on the frame corresponding to the left and right eye positions. The lens adjustment system includes a positive lens, a negative lens, a stepping motor, The transmission device and the circuit board. The output of the circuit board is connected to a stepping motor. The stepping motor drives the positive lens and / or the negative lens for relative movement through the transmission device; the prism adjustment device includes two circular prisms and a fixed bottom box. The circular triangular prism is installed in the fixed bottom box, and two circular triangular prisms are driven to rotate in the fixed bottom box by the adjusting gear in the base.

[0025] The above-mentioned transmission device is a stepping motor shaft gear and a rotating screw. The stepping motor shaft gear meshes with the rotati...

Abstract

The invention relates to an adjustable prism and lens combined myopia controller. A lens adjustment system and a prism adjustment device are installed on a frame respectively corresponding to the left eye position and the right eye position. The lens adjustment system consists of positive lenses, negative lenses, stepper motors, transmission units and circuit boards. The circuit boards are in output connection with the stepper motors, the stepper motors drive the positive lenses and / or negative lenses to do relative movement through the transmission units. The prism adjustment device comprises two round triangular prisms and a fixed bottom case, the two round triangular prisms are mounted in the fixed bottom case and are driven by an adjustment gear in the fixed bottom case to rotate in the fixed bottom case, and the base direction of the triangular prisms can be adjusted. The controller provided by the invention can adapt to teenagers' actual need for dioptre and set amount in reading books, watching computers, watching TV and other aspects, and can alleviate asthenopia, prevent and control juvenile myopia.

Description

Technical field [0001] The invention relates to the technical field of medical instruments, in particular to an adjustable prismatic lens combined myopia control instrument for preventing and controlling myopia of young people. Background technique [0002] The existing prism lens combination mirror is a fixed mode prism and lens, which is not adjustable and has a very single purpose. The existing telescopes on the market, although adjustable, are still limited to a simple lens without a prism combination, and manual adjustment is not suitable for young people's eyesight in different conditions such as reading, doing homework, watching TV, and watching the computer. Therefore, it cannot effectively prevent and control myopia in young people. Summary of the invention [0003] The technical problem to be solved by the present invention is to solve the above-mentioned problems in the prior art, and provide an adjustable prism lens combination myopia controller, which automatically a...
