What is meant by pseudomyopia? Pseudomyopia is relative to true myopia. True myopia is when the refractive system of the orthoptic eye is at rest, i.e., the far point of the eye lies within a finite distance after the effect of accommodation is removed. In other words, myopia is the result of congenital or acquired factors that cause the anterior and posterior diameters of the eye to become longer, and parallel light rays enter the eye and form a focal point in front of the retina, causing blurred vision. Pseudomyopia, on the other hand, is a condition in which there is still partial accommodation when looking at distant objects. It is common in adolescent students when looking at near objects, because the degree of using regulation is too strong and the duration is too long, resulting in continuous contraction of the ciliary muscle, causing regulation tension or apical spasm, so that after reading and writing for a long time to look at far, can not quickly relax the regulation, and cause dizziness, eye swelling, vision loss and other visual fatigue symptoms. This is called pseudomyopia because the refractive power of the eye is enhanced, leaving the eye in a myopic state. Both pseudomyopia and true myopia are characterized by symptoms of visual fatigue, poor distance vision and good near vision. However, pseudomyopia is a functional change, without the problem of the anterior and posterior diameter of the eye becoming longer, but only the adjustment spasm, after the ciliary muscle paralyzing drug point eye, most can be converted to farsighted or orthoptic eyes. If you wear myopic lenses under true myopia treatment, your eyes will feel very uncomfortable because it does not release the adjustment spasm, and there is even a risk of myopia development. What is true myopia? True myopia: also called axial myopia, in which the refractive power of the refractive interstitium is normal, the anterior and posterior diameters of the eye axis are prolonged, and light from a distance is imaged in front of the retina after entering the eye. The main clinical characteristics of true myopia are: 1. The degree of myopia is mostly medium or high myopia, which occurs and develops over a long period of time, and the patient’s eye has different degrees of emmetropia. 2. True myopia is difficult to self-adjust and recover. We believe that the major difference between true myopia and pseudomyopia lies in the normal refraction of the refractive interstitium (cornea, waterproof, lens, vitreous), while the visual axis becomes longer. The main reason for this is long-term near vision.
