Can myopia worsen astigmatism?
Many people have astigmatism, which can severely impair normal vision. Objects appear consistently blurry, and double images (ghosting) may even occur—causing significant difficulties in daily learning and work. To rapidly alleviate these symptoms, it is essential to first adopt the correct treatment approach. But does myopia worsen astigmatism?
Does Myopia Worsen Astigmatism?
Astigmatism does not exacerbate the degree of myopia; however, both astigmatism and myopia can jointly aggravate visual acuity loss. Clinically, both conditions are common but represent distinct concepts. Astigmatism arises from congenital asymmetry of the corneal curvature, causing light entering the eye to focus as a dispersed, non-point-like image on the retina—hence the term “astigmatism.” In contrast, myopia results from an elongated axial length of the eyeball, causing light to focus anterior to the retina rather than directly upon it—thus producing blurred distance vision.
Myopia typically progresses with growth and development, and both myopia and astigmatism contribute to clinical visual impairment. Therefore, while myopia may exacerbate the *symptoms* associated with astigmatism (e.g., increased blurriness or distortion), astigmatism itself does not increase the *degree* of myopia. The progression of myopia is influenced by factors such as near-work habits, reduced outdoor activity, and intrinsic ocular growth. Consequently, when astigmatism coexists with myopia, optical correction—such as properly prescribed spectacles—is essential. Additionally, correcting poor visual habits and increasing time spent outdoors are critical measures to help prevent further myopic progression.
In daily life, patients should maintain a positive mindset and actively cooperate with their physicians during treatment. Medications should be taken strictly as prescribed—both in terms of dosage and timing—and proper daily eye care must be observed to facilitate prompt improvement. We hope this information proves helpful to you.
