Blurred vision, redness, dilated pupils, and dizziness are my symptoms, what could this possibly be?

OTC meds?: Benadryl (diphenhydramine) will do this (any anticholinergic medicine can do this) Eye conditions like gluacoma can cause this. The vision is often blurred if the pupils are dilated. Excessive stimulants can do this (caffeine). If you find yourself making frequent trips to the refrigerator as well, check to see if someone is spiking your Ovaltine with marijuana. Otherwise go see the eye doctor
