Description
Technical Field
The invention belongs to an auxiliary instrument for eye vision training, in particular to an eye refraction shaping instrument for correcting myopia and astigmatism.
Background
The incidence of myopia and poor eyesight is high, and the public statistical data shows that the incidence of myopia and poor eyesight of pupils can reach more than 50% in high-incidence countries and regions, the incidence of myopia and poor eyesight of middle school students can reach more than 80%, and the incidence of myopia and poor eyesight of college students is higher. The main reason why the mechanism of the myopia is not clear, so that the myopia and the poor eyesight can develop naturally is that the safe and effective means and method for treating and preventing the myopia in society are still lacked. The traditional Chinese and western sports exercise eye or vision item is lack of content, and only eye exercises are available in China at present, but the exercise effect is poor. The existing myopia prevention and control instruments in the market are various, and the instruments for preventing and controlling astigmatism are lacked, and the instruments with obvious prevention and control effects are lacked, so that the market development of the myopia prevention and control instruments is slow. The clinical symptoms of myopia are essentially caused by increased eye power, resulting in imaging in front of the retina. Shortening the axial length of the eye can directly reduce the diopter of the eyeball. The axial length of the eye of a myopic patient is substantially longer than the normal axial length. The degree of myopia increases by about 300 degrees for every millimeter of increase in the eye axis. The current orthokeratology achieves the aim of preventing and controlling myopia by controlling the development of the axis of the eye in the medical principle. The principle of shortening the eye axis is designed on the instrument, and the prevention and control effect is obvious. The current instruments have some drawbacks: firstly, the length of the axis of the eye is difficult to control without contacting the eyeball; secondly, the contact with the cornea of the eyeball brings about germ infection, thirdly, the strength and the direction are difficult to control, so that the obvious effect is not achieved, and even adverse reaction is generated. Chinese patent 201710407370.0 discloses a myopic eyeball shaper which shortens the length of the axis of the eye by intermittent contact, thereby improving vision. However, such intermittent effects are difficult to achieve with continuous effects.
