Blurred vision during dizzy spells is quite normal. It’s quite frequent, partly because of a connection between the inner ear and the eye muscles. During severe attacks of dizziness, the patient may see the world blur in a moving way that sometimes they can see the world spin, or sometimes they see just a faint movement as if you are moving the camera when you are taking a movie. And of course the image is not quite clear. So that’s what the blurring is common in vestibular and balance problems, usually because of the connection between the inner ear, which is the on again off balance with the eye muscles.
