prosperous urban life, but the occurrence of myopia is not determined by yourself!

what is myopia?

myopia is a pathological state of seeing clearly near and not clearly far away. It belongs to ametropia. The visual object cannot converge on the visual membrane through the refraction of the ocular refractive system, so it cannot form a clear image on the retina. The main reason for the formation of

and

non hereditary myopia is the excessive adjustment burden brought by excessive reading and other close distance. If you use your eyes for a long time, the ciliary muscle will spasm and temporarily lose the ability to relax, resulting in unclear vision, resulting in false myopia.

in the long run, the spasmodic ciliary muscle may stimulate the stretching of the anterior and posterior axis of the eye, resulting in irreversible true myopia.

myopia degree generally exceeds 600 degrees, which is high myopia. Still did not take the influence of astigmatism into account, and did not consider whether there were lesions in the fundus of the eye!

most people’s myopia belongs to axial myopia: the anterior and posterior diameter of the eyeball becomes longer, just like a table tennis ball is pulled into the shape of an egg. As a result, the light cannot be focused on the retina, which makes the retina unable to accurately receive visual information, so it can’t see clearly.

the harm of myopia

the eyes are easy to be tired

the eyes are always narrowed when looking at things. Although it is to see more clearly, it is more laborious and the eyes are more likely to be tired. Especially for students, they have great learning pressure. In addition, if they read for a long time, their eyesight will decline faster and faster!

deepens the degree of myopia

for myopic eyes, if the degree of glasses does not match, or habitually squint, the degree of myopia will be higher and higher unconsciously. This is that many myopic people are clearly equipped with eyeglasses, but the degree is gradually deepened. The

and

eyes have astigmatism. The

and

squint can improve vision to a certain extent through the pinhole effect and fissure effect in physics. Therefore, astigmatism patients often squint when looking far away. After wearing glasses, they can correct this bad habit. It should be noted that squinting is not an inherent manifestation of astigmatism, and it can also occur in patients with myopia.

high myopia try not to exercise violently. Patients with

high myopia need to avoid strenuous exercise, especially activities with direct impact or obvious concussion on the eyes and head.

because the eyeball is “elongated”, all layers of tissue in the eyeball wall will become thinner and shrink accordingly. Especially after the retina becomes thinner, it is easy to cause degenerative zones and holes around the retina, which will further lead to retinal detachment; The macular region in the center of the retina may also have various pathological changes such as holes or bleeding, which will seriously affect vision.

these lesions can cause blindness. Some can be prevented and treated by laser or surgery in time, while others do not have good treatment. Their eyesight may become very poor, and wearing glasses does not work.

in addition, in addition to fundus retinopathy, people with high myopia are also prone to lens dislocation, cataract, open-angle glaucoma and other problems.
