Separate shielding device for left and right eyes

technical field

The invention belongs to the field of medical equipment, and relates to a device for independently shielding left and right eyes used in a myopia, especially amblyopia treatment instrument.

Background technique

Amblyopia is an eye disease that seriously endangers children's visual function. If it is not treated in time, it can lead to aggravation of amblyopia and even blindness. Amblyopia treatment specifically refers to the treatment of amblyopia in children, because the child's visual function is in the developmental stage, through treatment can gradually improve vision, the younger the better the treatment effect, the treatment of amblyopia after 12 years old, the difficulty of vision recovery Larger, the degree of recovery of visual function is low, the quality is relatively poor, or even impossible to recover.

Patches and optical corrections are the cornerstones of amblyopia treatment. Especially for amblyopia patients with inconsistent degrees of amblyopia in both eyes, the scientificity and implementation of the covering plan play an absolute role in the effect of amblyopia treatment.

The most common method of covering is covering the healthy eye (the better eye). After the healthy eye is covered and deprived of vision, the poor eye can gain the opportunity of visual perception and visual input, so that the poor eye can get exercise and excitement.

However, covering needs to be combined with the condition and age, and the daily covering time should not be too long to prevent covering amblyopia. At present, there are various treatment devices for myopia and amblyopia on the market, but these treatment devices still do not get rid of the traditional cover. After determining the eye with better vision, the method of covering the eye is often directly used to cover the eye. This method of operation It is bothersome, inconvenient when covering and taking off, and easily arouses users, especially children's boredom.
