4. Nerve and Brain Issues

Blurred vision can result from nerve and brain issues, even if the eye is otherwise healthy. When light strikes the retina, the optic nerve carries the signals to the brain, which deciphers them and forms images that we perceive as vision. Inflammation or compression of the optic nerve interferes with the signals that are carried to the brain and can result in blurred vision. Traumatic brain injury, brain tumor, stroke, and other problems involving the brain can cause blurry vision, as well.
