Age-related changes to the eye are the most common cause of eye floaters. The cornea and lens at the front of the eye focus light onto the retina at the back of the eye. As the light passes from the front of the eye to the back, it passes through the vitreous humor, a jelly-like substance inside your eyeball.
Manifest-latent nystagmus is continually present, but worsens when one eye is covered. Acquired nystagmus can be caused by a disease (multiple sclerosis, brain tumor, diabetic neuropathy), an accident (head injury), or a neurological problem (side effect of a medication). Hyperventilation, a flashing light in front of one eye, nicotine and even vibrations have been known to cause nystagmus in rare cases.
