Image-amplifying stadia-increasing visual angle-adjusting myopia prevention device

Abstract

An image-amplifying stadia-increasing visual angle-adjusting myopia prevention device comprises a cabinet, a column, a camera shooting support, a projection support, a mirroring support, a camera, an illuminating lamp, a display, a mirror, and a remote controller; the column is arranged on the cabinet top; the column top is connected with the camera shooting support through a rotary seat; the camera and the illuminating lamp are arranged in front of the camera shooting support; the column lower portion close to the rotary seat is provided with a bearing; the bearing outer wall is connected with the projection support; the projection support end is connected with the display; the cabinet top edge is provided with a fixed seat; the fixed seat is connected with one end of the mirroring support; the mirroring support end is connected with the mirror; a battery and a control host are arranged in the cabinet. The image-amplifying stadia-increasing visual angle-adjusting myopia prevention device uses the camera to capture images, uses the display to display said images, uses the mirror to reflect the images, so users can observe the images in the mirror; the mirror reflection can increase the stadia, thus effectively preventing myopia; the image-amplifying stadia-increasing visual angle-adjusting myopia prevention device is more convenient to use.

Description

technical field [0001] The invention relates to the field of anti-myopia devices, in particular to an anti-myopia device with an enlarged image, increased viewing distance, and adjustable viewing angle. Background technique [0002] The most direct cause of myopia is long-term close viewing of things, which leads to visual nerve fatigue, and the focus of parallel light falls in front of the retina after being refracted by the refractive system of the eye. Therefore, the most important means to prevent myopia is to maintain the visual distance when viewing things. The current crowd, especially students, due to the high pressure of study and long-time reading, makes most of the students suffer from myopia. At present, there are many instruments for preventing myopia on the market, the main purpose of which is to ensure the correct sitting posture when reading and keep a reasonable distance from the book. Not free enough, long-term use will cause physical discomfort, users wi...
