What is the cause of amblyopia?

There are many reasons for amblyopia, mainly including refractive error, strabismus, abnormal eye movement, high myopia and lack of visual stimulation. 1, refractive error is the eye on the focus of light problems, such as myopia, hyperopia, astigmatism, etc., if not corrected in time, may lead to blurred images received by the eye, and thus affect visual development, forming amblyopia. Strabismus is the abnormal position of the eyeball, resulting in two eyes can not accurately aim at the same target at the same time, so that the brain can not be received by the two eyes into a clear image synthesis, resulting in amblyopia. 3. Abnormal eye movement may also lead to amblyopia. If the movement ability of one eye is impaired and cannot be synchronized with the other eye, it will cause the brain to suppress the images it receives, thus forming amblyopia. 4. Abnormal eye structure of high myopia may lead to damage or thinning of the retina, which in turn affects visual development and produces amblyopia. 5, lack of visual stimulation, such as children in the critical period of lack of sufficient visual stimulation, such as light, color, shape, etc., the development of the visual system may be limited, leading to the formation of amblyopia.
