Introduction
In general, myopia can be categorized into two types: pseudomyopia and true myopia. Pseudomyopia is usually reversible, whereas true myopia may not be reversible. If vision problems occur, it is important to seek medical advice as early as possible. In daily life, one should practice proper eye use and avoid prolonged screen time to prevent eye damage.
In general, myopia can be categorized into two types: pseudo-myopia and true myopia. Pseudo-myopia is usually reversible, whereas true myopia is generally irreversible. If vision problems occur, it is important to seek medical advice as early as possible. The specific analysis is as follows:
1. Reversible
Pseudo-myopia typically results from prolonged tension in the eye muscles, leading to decreased lens accommodation ability and a temporary change in the eye's focal length, thus causing nearsightedness. In such cases, vision can often improve significantly through proper eye rest, relaxation of eye muscles, controlling screen time, and using appropriate eyeglasses or contact lenses.
2. Irreversible
True myopia occurs due to structural changes in the eye's refractive system, such as an elongated axial length, excessive corneal curvature, or lens deformation, which prevent distant objects from focusing accurately on the retina. In these cases, restoring vision is usually difficult. Although vision can be corrected with glasses, contact lenses, orthokeratology lenses, or laser refractive surgery, true myopia cannot be fundamentally cured because the underlying cause—structural changes in the eye—cannot be reversed to the original state.
In daily life, it is important to practice proper eye usage and avoid prolonged exposure to electronic screens that may harm the eyes.
