Gorilla glasses make it appear as if you aren't really looking at what you're looking at (unless you're trying to see your own brain), so gorillas won't kick your ass for making eye contact. They also work for staring at boobs (wear them over x-ray specs).
The Rotterdam Zoo is giving away cardboard glasses that make it appear that you're looking off to one side; these are gorilla-viewing glasses, meant to avoid incidents in which gorillas attack visitors for making eye contact with them. The glasses' introduction follows an attack on a woman by an escaped gorilla...
The specs are sponsored by a local health-insurance company.
Well of course the glasses are sponsored by a local health-insurance company, that's just good business. Nothing drives up your premium like getting beat to shit by a gorilla.

Thanks to hildabot, who was once chased by a gorilla but remembered to stop, drop and roll like she learned in school.
