What symptom does eye myopia have?

First: the most prominent symptom of myopia is the decrease of far vision, but the near vision can be normal. Although the higher the degree of myopia, the worse the distant vision, but there is no strict proportion. Generally speaking, for myopia above 300 degrees, the far vision will not exceed 0.1; 2-0.3 for 200 degrees; 1.00d can reach 0.5, sometimes better.

Second: especially in the low degree of common, but not as obvious as hyperopia. It is due to the disharmony between regulation and collection. In high myopia, because the fixation target is too close to the eye, the collective effect can not cooperate with it, so monocular fixation is often used, which will not cause visual fatigue.

Third: because myopic eyes do not need to adjust the nearsightedness, so 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, and the other eye leans to the outside, becoming 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.
