Background
The eye-using habit of the unhealthy teenagers causes the outbreak of large area of myopia. The reason for this is that when eyes are used for a long time at a short distance, paralysis and spasm of ciliary muscles gradually change from pseudomyopia to true myopia. At present, besides surgery, drug treatment or optical glasses correction, the aim of preventing and controlling myopia can be achieved by exercising ciliary muscles to recover the vitality of the ciliary muscles. The ciliary muscle exercise can be achieved by an eye muscle exercise, which includes the exercise of the outer and inner muscle groups of the eye. The exercise of the ciliary muscle in the eyeball is represented by a visual target movement method represented by a straight line training instrument, and the effect is obvious. In actual life, a large amount of time is occupied by training of vast teenagers due to heavy learning tasks, one to two hours are usually needed for training once, more time is consumed for long-term round trip to a hospital or a rehabilitation center, and eyeball muscle training is boring, tasteless, tedious and troublesome, and myopia patients cannot persist. The eye muscle training for correcting the myopia is a long-term process, which directly causes that the teenager patients are difficult to adhere to the training for a long time and directly influences the effect of myopia control treatment.
