Blurred Vision: Symptoms & Signs

  • Medical Author: Melissa Conrad Stöppler, MD

Blurred vision refers to a lack of sharpness of vision resulting in the inability to see fine detail. Blurred vision may result from abnormalities such as nearsightedness, farsightedness, presbyopia, or astigmatism that can be improved with corrective lenses (eyeglasses) or it may signal the presence of eye disease. Blurry vision may be experienced in one eye or in both eyes, depending upon the cause. Blurred vision can also be a symptom of numerous conditions that do not directly involve the eye, such as migraine or stroke. A number of medications may also lead to temporary blurring of vision as a side effect. Sometimes, blurred vision is associated with other symptoms, depending upon its cause, including headache, sensitivity to light, or redness and irritation of the eyes.
