Many people have a one-sided understanding of the symptoms of myopia. Doubt is a manifestation of decreased vision. In fact, the symptoms of myopia are manifested in many aspects. What symptom does myopia have below me? Let me tell you this.

What symptom does myopia have?

First: fundus: low myopia fundus change is not obvious, high myopia, due to excessive elongation of the eye axis, can cause fundus degeneration.

Second: eye position: because myopia does not need to adjust the near vision, the collection function is relatively weakened. When the muscle balance cannot be maintained, the binocular visual function will be destroyed. Only one eye can see the object, and the other eye tends to the outside, which becomes temporary alternating strabismus. If the visual function of the deviated eye is very poor and the deviation occurs earlier, it can make the deviated eye lose the ability of fixation and become monocular exotropia.

Third: eyeball: high myopia, mostly belongs to axial myopia, eyeball before and after axis elongation, its elongation is almost limited to the posterior pole. So often performance eyeball is more outstanding, anterior chamber is deeper, pupil is big and reflex is blunt. The ciliary muscle, especially the annular part, becomes atrophic due to the absence of accommodative stimulation. In very high myopia, the lens can not support the iris completely, resulting in mild iris tremor.
