Myopia can occur if you wear glasses for a long period of time without being nearsighted.
Myopia is a type of refractive error, which means that parallel light rays from the outside world are refracted by the refractive system of the eye and then converge to form a focal point in front of the retina, which makes the projection of the scene on the retina of the patient become blurred, thus leading to a loss of visual acuity.
If a non-myopic patient wears myopic glasses, it will interfere with the normal operation of the refractive system of the patient’s eyes, which will make the patient prone to visual fatigue and other symptoms, and may induce the formation of myopia, especially for a long period of time, the risk of wearing myopic glasses will be higher.
Therefore, it is not recommended that patients who are not nearsighted try to wear myopic glasses out of curiosity or for other reasons, and to seek medical attention in case of discomfort.
