Generally, patients themselves have no way to recognize true myopia from false myopia, and need to go through a formal eye examination to differentiate.
True myopia is usually caused by acquired poor eye habits. The main reason is that the anterior and posterior diameters of the eyeballs become longer, and parallel rays of light enter the eye and form a focal point in front of the retina, resulting in blurred vision, which is also known as axial myopia. In addition to being caused by poor eye habits later in life, there are also congenital causes of true myopia, which is usually caused by heredity.
Pseudomyopia, which has symptoms similar to myopia, is therefore called pseudomyopia. The main reason is the incorrect eye habits, resulting in high eye regulation, ciliary muscle to be highly contracted, will make the eye regulation is abnormally tense, the ciliary muscle long-term contraction spasm state, and finally lost the regulating properties, the vision of the far side of the decline, the performance of myopia like cool.
If you want to recognize the real myopia, the best way is to go to the hospital for formal eye examination, such as dilated pupil optometry and other tests, after perfecting the examination to clarify whether it is true myopia or pseudomyopia, and intervene if necessary.
