Definition for Blurred vision
From Biology Forums Dictionary
Blurred vision refers to a lack of sharpness of vision resulting in the inability to see fine detail. Blurred vision may result from abnormalities present at birth such as nearsightedness or farsightedness that require corrective lenses (glasses) or it may signal the presence of eye disease. 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.
