Description

Eye training device

Technical Field

The utility model relates to the field of medical equipment, in particular to an eye training device.

Background

Binocular vision refers to that external object images respectively fall on corresponding points of retina of two eyes, and the brain advanced center combines visual information analysis from two eyes into a complete visual image with stereoscopic impression. Strabismus refers to the abnormal position of the eyeball. Strabismus and amblyopia have a high incidence worldwide, and normal people see one thing with both eyes, and the eyes keep parallel to each other and focus on one thing. The eyes of strabismus patients are not parallel, one eye looks at things, and the other eye is in a skew state and departs from the looking things. Because the eyes can not keep the parallel concentrated watching of the same thing, the images of the thing can fall outside the center, at the moment, the double vision phenomenon occurs to the eyes, the visual function is easy to be damaged due to strabismus, the images of the strabismus eyes can be restrained, the single visual function and the three-dimensional sense of the two eyes are lost, and the weak vision is caused by serious vision dysplasia.

Existing training devices typically employ a single-sided solid mirror that trains the eyes by allowing the user to see different pictures through both eyes. Because of the variety of drawings used in training, and because such drawings are typically paper, they are easily lost and damaged. The pupil distance of each person may vary, and the fixed eyepiece distance and fixed picture start position or the adjustable eyepiece distance and fixed picture start position are both imprecise. It is the correct way to have an adjustable eyepiece distance and to determine the starting position of the display piece based on the eyepiece distance. Meanwhile, the moving of the drawing is manually moved by a user, so that uneven moving speed of the drawing is easy to cause, and the drawing is difficult to ensure to move on a straight line. In order to manually move the picture, and enough light exists, the existing single-side solid mirror is open, so that when eyes watch the picture through the ocular lens, other images around the picture are almost always received, the left eye and the right eye are separated, and the received other images have larger differences, and the differences cause interference to the brain of a user when fusion is carried out.
