In episode 9 season 2 Edd mentions a time when blind and later received sight in some sort of miraculous occurenece. Afterward, his parents (who are neurosugeons) remove his brain to experiment and discover the cure from his blindness. At this point a jar or pickles that has been festering in Eddy's basement for an unknown amount of time is placed into Edd's head as a transplant. This leaves unsightly scars and buldges in his scalp and thus, the hat.
