[Sullivan, p. 1209] Organophoshosphates and carbamates can cause miosis and temporary blurred vision. Symptoms of acute carbon monoxide poisoning can include dimmed vision. Other reported causes of visual impairment are lead poisoning, organic mercury and tin poisoning and chronic toluene abuse (sniffing).
