Loss of sharpness in vision

Blurry vision can be caused by refractive errors in the eye, but it can also be a symptom of more serious diseases or neurological disorders. If you suffer from blurred vision, it's important to talk to your eye doctor to determine the cause and appropriate treatment.

Blurred vision can be the result of abnormalities present at birth, or it can be the result of aging. Many people who complain of a lack of sharpness in their vision are diagnosed with either hyperopia (farsightedness), myopia (nearsightedness), astigmatism or presbyopia, all of which can be treated with corrective lenses. Blurry vision can also be a symptom of sight-threatening eye diseases, as well as health conditions not directly related to the eye, like diabetes, migraine or stroke. Hormonal changed during pregnancy may also cause blurry vision.

Blurred vision can be a temporary side effect of some medications, such as allergy pills, and some eye drops can cause irritation that leads to blurred vision.
