Just now, I saw a TV commercial here in Japan for some eye drops. According to the commercial, the eye drops aren't for red eyes, allergies, or even contact lens dry out. No. Instead, they're being sold as eye drops that help you out when you're tired.

Eyes feel tired? Use these drops for ultimate refreshment. Forget going to sleep. Forget taking some vacation time. Need to work! Have to work! Must work! Put a drop in each eye and I'm good to go. After all, a few milliliters of this miracle fluid is the same thing as a good night's rest.
