Many parents find that their children like to squint, watch TV very close, like to rub their eyes with their hands, and children can not see the blackboard in class, so parents worry that their children are not really myopic, in order not to affect learning, so blindly go to the optician with myopic glasses. This is not the right approach. Myopia, we all know, but do you know how to distinguish between true and false myopia? Pseudomyopia is also known as regulatory myopia. It refers to a person whose eyes are in a myopic state due to continuous contraction of the ciliary muscle and over-adjustment due to various reasons, forming a regulatory spasm that increases the refractive power of the lens. This myopic state disappears when the regulation is paralyzed. Because this is not true myopia, but rather a phenomenon of over-regulation, it is also known as regulatory myopia. The degree of pseudomyopia is represented by the amount and duration of the eye accommodation tension. The concept of “pseudomyopia” was first introduced, not for adolescent myopia, but for hyperopia. Because farsighted eyes do not see clearly at a distance and are more blurred at a near distance, they need to use regulation, resulting in excessive tension or even spasm of regulation, which shows some myopia symptoms such as blurred vision at a distance, slightly clear vision at a near distance, squinting, and myopia with a small pupil. Once the regulation is relaxed (such as the use of ciliary muscle paralyzing agents), then the examination is farsighted. Therefore, parents should go to the hospital as soon as possible when they find that their child’s vision is declining, and after regular dilated eye examinations, wear glasses under the guidance of an ophthalmologist, as well as regular follow-up visits to see if glasses need to be replaced in a timely manner.
