How parents can identify whether their child is true myopia or false myopia

Many parents find that their children's vision is blurry. They don't know if it is true myopia or false myopia? How to identify? Do you want to go to the optical store to get glasses? What if it is pseudomyopia? The following editor will give an official explanation of false myopia and true myopia, hoping to help parents. According to the changes in the diopter of myopia after the use of paralyzing drugs, it can be divided into true myopia, pseudomyopia, and mixed myopia. Pseudo-myopia: due to overuse of the eye, the ciliary muscle continues to contract and spasm, the thickness of the lens increases, and the vision is blurred. True myopia: After using atropine for mydriasis, the degree of myopia remains unchanged or decreases by less than 50 degrees. Mixed myopia: True myopia has components of pseudo-myopia. After mydriasis with atropine, the degree of myopia is significantly reduced (the degree of reduction is greater than 50 degrees), but the face has not been restored. Both true myopia and pseudo-myopia show blurred vision in distance and clear vision in near vision. True myopia involves the organic changes of the eye, such as the lengthening or shortening of the eye axis, the change of corneal curvature or refractive index, These changes are irreversible and cannot be recovered with vision correction or training. However, pseudo-myopia is different. It is only abnormal adjustment function and ciliary muscle spasm. It is necessary to correct bad eye habits in time or recover through visual training. Once parents find that their children are squinting from a distance and other symptoms, they should first take their children to the hospital for dilated optometry to determine the nature of myopia.
