The u.S.National library of medicine toxicology data network (toxnet) describes the scope of injury associated with hydrogen peroxide exposure to the ocular tissue, ¿hydrogen peroxide is irritating to the eyes with a burning sensation, conjunctival hyperemia, lacrimation and severe pain which resolves within a few hours.There are rare cases of temporary corneal injury resulting from the application of 3% solution to the eye on contact lenses including punctate staining of the cornea, decreased vision, corneal opacity and edema.¿ in large part, the events described are not consistent with application of unneutralized hydrogen peroxide coming in contact with the eye.The primary long-term events reported by the consumer are associated with the posterior chamber of the eye; whereas exposure to unneutralized hydrogen peroxide signs and symptoms are associated with the cornea and conjunctiva and are of short-term duration.The complaint sample was not returned for evaluation.
