Early and late symptoms of myopia teach you to judge whether you are myopia

Abstract: in life, we can know that the other party has myopia by looking at the wearing of other people’s eyes, but it does not mean that the vision of people without eyes must be normal. Therefore, through the understanding of the symptoms of myopia, we can see whether they have myopia in time. So, what are the symptoms of myopia?

symptoms of early myopia

1. Eye fatigue. The symptoms of early myopia of


are that the handwriting feels ghosting and floating instability when reading. When some people move to a nearby object after looking at a long time, or move to a distant object after looking at a long time, there will be a short ambiguity in front of them.

2. General nervous disorders.


the symptoms of myopia in children also include general nervous disorders. Some students with good grades will be bored with learning, lack of concentration during class, slow response, irritable temper, lack of interest in the original favorite things, decline in academic performance, dreamy and sweaty at night, easy to be tired and dizzy Loss of appetite and other symptoms. This is a manifestation of central and autonomic nerve disorders caused by eye fatigue.

3. Perceptual allergy.


refer to the fatigue perceptual allergy of ocular sensory nerves. Many people will also have dry eyes, burning, itching and eye pain. Some people’s swelling pain can spread to the deep part of the orbit, and even cause migraine, and even pain in the neck, shoulder and back. These are the symptoms of myopia in children.

symptoms of late myopia

generally myopia will not develop in adulthood, and those who continue to develop after the age of 25 are called progressive myopia. In terms of diopter, Those with more than 6.0d (600 degrees) are called high myopia. Almost all high myopia have eye axis growth and significant thinning of sclera at the posterior pole of the eye. The main pathological changes are atrophy and thinning of retina and choroid, which are aggravated year by year. Therefore, many serious complications may occur, most of which can cause blindness. It is the sixth blinding disease in China.

1. High myopia of eyeball mostly belongs to axial myopia. The anterior and posterior axis of eyeball is elongated, and its elongation is almost limited to the posterior pole. Therefore, it often shows that the eyeball is prominent, the anterior chamber is deep, the pupil is large and the reflex is slow. Because there is no regulatory stimulation, the symptom of myopia is that the ciliary muscle, especially the annular part, becomes atrophic. In very high myopia, the lens can not support the iris at all, resulting in mild iris tremor.

2. The symptom of visual myopia is the decrease of far vision, but the near vision can be normal. Although the higher the degree of myopia, the worse the far vision, there is no strict proportion.

3. Visual fatigue, a symptom of myopia, is common in low-grade people, but it is not as obvious as hyperopia. It is caused by the disharmony between regulation and collection. For 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, but it will not cause visual fatigue.
