Causes and Treatment for Blurry Peripheral Vision. 1. Migraine. Migraines are severe headaches caused by narrowing of the blood vessels (vasoconstriction), followed by widening of the vessels (vasodilation). When the vessels are narrowed, blood flow is reduced, which affects the eye.
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.
