Rare commercial version: A famous Rayban commercial suggested that seeing direct sunlight was what harmed vampires. It showed a group of them gathered on a seawall, watching the sun rise over the ocean; it's only when one fails to put on his shades (and suffers the consequences) that we find out what they are. Maybe it wasn't the seeing of sunlight. Maybe the glasses were just that good.
