Why can’t you see well even though you’re not nearsighted?

If a patient has low myopia but cannot see clearly, it may be caused by astigmatism, refractive error and other eye diseases.
If astigmatism is present in a myopic patient, even if the myopia is not high, the patient may experience blurred vision, double vision and other uncomfortable symptoms, and the patient can correct the refractive error by wearing the appropriate glasses to improve vision.
Refractive error can be corrected by wearing appropriate glasses to improve the vision. The refractive state of the two eyes is not consistent with each other, which is called refractive error. Even if the patient’s myopia is not high, but the refractive error between the two eyes is not consistent, the patient may also experience blurred vision and other uncomfortable symptoms.
If the patient suffers from other eye diseases such as keratitis, cataract, glaucoma, macular degeneration, optic neuropathy, etc. in addition to myopia, the patient may experience blurred vision even if the myopia is not high.
It is recommended that myopic patients with significant vision loss should seek prompt medical attention to assess their condition and follow the doctor’s instructions for treatment.
