Introduction
Astigmatism and myopia cannot be said to be “curable,” but both can be effectively controlled simultaneously. Both myopia and astigmatism are types of refractive errors. Myopia occurs when light from external objects focuses in front of the retina, resulting in blurred vision for both near and distant objects. Astigmatism causes blurred vision at all distances—near or far. These two conditions are independent of each other and may coexist in the same patient; therefore, correction is performed separately and independently for each.
With the widespread use of various electronic devices, people’s lives have become increasingly convenient. However, at the same time, an increasing number of individuals are developing eye conditions such as astigmatism and myopia. Both are common refractive errors that significantly impact ocular health and therefore warrant adequate attention. So, can astigmatism and myopia be cured?
Can Astigmatism and Myopia Be Cured?
Astigmatism and myopia cannot be considered “cured” per se, but both can be effectively managed and controlled simultaneously. Both conditions represent types of refractive error. Myopia occurs when external light rays focus in front of the retina, resulting in blurred vision for both near and distant objects. Astigmatism, by contrast, causes blurred vision at all distances—near or far—due to irregular corneal or lens curvature. These two conditions are independent of each other, yet they may coexist in the same individual; thus, correction is performed separately and individually, although it can be achieved concurrently. For adult patients wishing to eliminate their dependence on glasses or contact lenses, refractive surgery (e.g., LASIK or SMILE) can correct both myopia and astigmatism in a single procedure. Therefore, while myopia and astigmatism can be corrected simultaneously, “correction” does not equate to “cure,” and neither condition can be permanently eradicated.
When using computers and smartphones, avoid setting screen brightness too high. Instead, adjust brightness to a level comfortable for your eyes to prevent visual strain caused by excessive brightness or dimness. When using laptops or desktops, maintain a minimum distance of 50 cm between your eyes and the screen. Prolonged screen use—especially without breaks—can cause significant ocular stress and damage.
In daily life, cultivate healthy lifestyle and dietary habits. We hope this information proves helpful to you.
