Can myopia degree be reduced?

Generally speaking, whether myopia (nearsightedness) refractive error can decrease is not a straightforward “yes” or “no” answer—it largely depends on the type of myopia and the individual’s ocular developmental status. A case-specific analysis is required, as detailed below:

In individuals with pseudomyopia, refractive error may return to normal. Pseudomyopia commonly occurs in adolescents or those who engage in excessive near work. It does not involve structural (organic) changes to the eye; rather, it results from sustained ciliary muscle spasm and abnormal accommodation, leading to temporary visual blurring—specifically, blurred distance vision while near vision remains clear. With appropriate interventions—including reducing near-vision tasks, avoiding late-night activities, increasing outdoor time, performing eye exercises to relax the ciliary muscle, and applying warm compresses to alleviate visual fatigue—the ciliary muscle can gradually regain normal accommodative function. Consequently, refractive error may decrease or even normalize, eliminating the need for corrective eyewear.

In contrast, individuals with true (axial) myopia cannot spontaneously reduce their refractive error. True myopia involves an organic structural change in the eye—specifically, elongation of the axial length. Once the eye axis has lengthened, it cannot be shortened non-surgically; therefore, myopia progression cannot be reversed. Whether in adolescents or adults, after a confirmed diagnosis of true myopia, refractive error can only be stabilized—not reduced—through proper visual hygiene. Even corrective measures such as spectacles or contact lenses merely improve visual clarity without altering the underlying refractive error. Only refractive surgical procedures (e.g., laser surgery) can correct vision and reduce dependence on glasses—but they do not truly reverse or lower the pre-existing degree of myopia.

In daily life, prolonged near-vision tasks should be avoided. After approximately 40 minutes of sustained near work, take a 5–10 minute break to gaze into the distance and relax the ciliary muscle. Additionally, ensure adequate daily outdoor activity and regular exposure to natural light to promote ocular blood circulation.
