Amblyopia correcting instrument

Abstract

The invention discloses an amblyopia correcting instrument. The instrument comprises a lens barrel, a liquid crystal touch screen, a liquid crystal touch screen box, a base and two fixed lantern rings; the lens barrel is arranged on the upper portion of the liquid crystal touch screen box which is fixedly arranged on the upper surface of the base, the liquid crystal touch screen box is internallyprovided with the liquid crystal touch screen, a selection switch is arranged on the upper surface of the right end of the base outside the liquid crystal touch screen box, each fixed lantern ring inthe device is formed by two semi-ring-shaped structures with the same specification through mutual fitting and fixing, the lens barrel is fixed through the fixed lantern rings which are arranged on the upper portion and the lower portion of the lens barrel, the upper end and the lower end of the lens barrel can be fixed, the fixing structure is stable, and correcting of amblyopia cannot be affected due to instability; a parallel rotation fixed support rotates vertically relative to a vertical rotation fixing support, the lens barrel can be inclined, a parallel rotation frame rotates in parallel relative to the parallel rotation fixed support, the horizontal position of the lens barrel can change, a support cylinder rod is rotated, and then the whole lens barrel can rotate; the purpose of multi-directional regulation is achieved, and the instrument can be used according to actual demand conveniently.

Description

technical field [0001] The invention relates to the technical field of amblyopia correction instruments, in particular to an amblyopia correction instrument. Background technique [0002] Eyeball without obvious organic lesions, and the corrected visual acuity of one eye or both eyes still does not reach 0.8 is called amblyopia. At present, the standard of amblyopia in my country is that the corrected visual acuity is ≤0.8 or the visual acuity difference of both eyes is ≥2 lines. Amblyopia is an eye disease that seriously endangers the visual function of children. If it is not treated in time, it can lead to aggravation of amblyopia and even blindness. Amblyopia correction device is an instrument for the treatment of amblyopia, but this amblyopia correction device still has the following drawbacks in actual use: [0003] 1. The existing amblyopia correction instrument needs to be used in conjunction with the changing position of the human body, and the body of the amblyopia...

AI Technical Summary

Problems solved by technology

[0003] 1. The existing amblyopia correction device needs to be used in conjunction with changes in the position of the human body. The body of the amblyopia correction device is often not easy to adjust in multiple directions, and it is inconvenient to use;

[0004] 2. In the existing amblyopia correction device, the lens barrel is not fixed very firmly, which is not convenient for observation and correction of amblyopia
