Remote reading system to control the development of juvenile myopia? Application number: 201210194161.x Application date: 20 12.06.6438+03.
A remote reading system for controlling the development of myopia of teenagers comprises a shell, an optical amplifying element and a collimating element which are sequentially arranged in the shell, a bracket and a light source positioned at the bracket side, wherein the optical amplifying element comprises a lens and a first plane reflector which are sequentially arranged above the bracket, a spectroscope and a concave mirror for receiving the light reflected by the first plane reflector, a second plane reflector which is positioned above the spectroscope for receiving the light reflected by the spectroscope and a screen for receiving the light reflected by the second plane reflector; The collimating elements are a beam splitter and a second plane mirror, and the middle lines of the beam splitter and the second plane mirror are respectively provided with a beam splitter knob and a second plane mirror knob for adjusting the mirror angle. The invention can make people feel that characters and figures are 5 meters away when reading, and relieve the visual fatigue caused by excessive use of eyes at close range, thus slowing down the development of myopia.
Remote reading device for relieving visual fatigue?
ApplicationNo.: 20 12 10322984.6 Application Date: 20 12.09.04.
Abstract:? A remote reading device for relieving visual fatigue comprises a bracket, a light source, a reading screen, an optical element arranged in the bracket and a platform for placing reading materials, wherein the optical element comprises a magnifying glass groupNo. 1, a plane reflectorNo. 1, a magnifying glass group No.2 and a plane reflector No.2 which are arranged in sequence along the light path direction; The reading screen is used to receive the reflected light of the No.2 plane reflector, and the reading material is amplified several times by the optical amplification element, and then reflected even several times. Through the optical design of the system, the invention makes teenagers feel that characters and graphics come from 2 meters away when reading, and can achieve the effect of long-distance reading under the condition of short-distance reading, relax the adjustment and collection generated by short-distance reading, and relieve the visual fatigue generated by short-distance reading when reading, thus controlling the development of myopia. It can be widely used to relieve the visual fatigue caused by teenagers' close reading. ?
