Nowadays, myopia can be corrected surgically (refractive surgery). <br \/>Unlike farsightedness, nearsightedness does not have the possibility of self-correction.<\/p>\n<p>In myopia, the dioptric power of the eye and the size of the eye are not in the correct relationship, either the dioptric power of the refractive system of the eye is too large or the eye axis is too long (too large an eye).<br \/><br style=\"font-weight: bold;\"><span style=\"font-weight: bold;\">In the refractive view, myopia is divided into:<\/span><\/p>\n<ul>\n<li><span style=\"font-weight: bold;\">Axial myopia<\/span> &#8211; it is caused by the stretching of the back half of the eye, and the optical axis is longer than 24 mm.
