Therapeutic instrument for correcting myopia by naked-eye staring

Abstract

The utility model relates to a therapeutic instrument, which is simple in structure and can gradually improve vision by long-term staring training of eyes in or out of a distance of distinct vision ofeyes, for correcting myopia by naked-eye staring. The therapeutic instrument is placed in a vertical or horizontal posture on a desktop beyond the near point of the eyes of a staring person or hung on a wall beyond the near point of the eyes of the staring person. A light window is arranged on the front of a shell, and a rear-stage reflector capable of clearing imaging character patters on an object space target plate in such a manner that the size of the aperture angle entering the pupils of the staring person is adjustable and located in the near point position of the eyes of the staring person and reflecting out of the shell via the light window is arranged in the position, opposite to the light window, of the shell. The myopic patient can use the therapeutic instrument, under the condition of relaxation of ciliary muscle, the ciliary muscle is trained by adjusting the size of the aperture angle of images in human eyes stage by stage, and the ciliary muscle of myopia can recover to original adjusting capacity after long-term training.

Description

technical field [0001] The invention relates to a therapeutic apparatus capable of correcting myopia, in particular to a therapeutic apparatus capable of achieving a better correction effect after standing at a certain distance and gazing at it with naked eyes after long-term training. Background technique [0002] As we all know, it is very beneficial for the nearsighted people to look far away without naked eyes.

Problems solved by technology

[0004] The existing home myopia treatment equipment usually needs to be used close to the user's eyes. The virtual perspective area is small, the clarity is extremely poor, the distance cannot be adjusted, and the distance and near vision cannot be alternated. The curative effect is not good. And close to the eyes, it is easy to bring bacteria to the eyes, which brings potential infection risks

The professional medical myopia treatment instrument is bulky, expensive and complicated to operate, so it is not suitable for home use.
