What is pseudomyopia: Pseudomyopia is relative to true myopia. It is common in adolescents when looking at near objects, because the degree of use of regulation is too strong and lasts too long, resulting in continuous contraction of the ciliary muscle, causing regulatory tension or spasm, so that after reading and writing for a long time to look at the distance, can not quickly relax the regulation, resulting in dizziness, eye swelling, vision loss and other vision fatigue symptoms. This is called pseudomyopia because the refractive power of the eye is enhanced, leaving the eye in a myopic state. 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. 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 that can be cured, but it can also develop into true myopia. True myopia is difficult to self-adjust and can only be slowed down by some treatments and health care methods.
