The weekend can take a toll on your eyes. Smoky clubs. Lots of drinking. Late nights. By Sunday your eyes are looking redder than Carrot Top after a day on the beach. And you're dragging more ass than JLo. (I know, two bad celeb references.)

For years, club kids and college students in Japan and the UK have been using Rohto V (pronounced row tow vee), eye drops to lose the red, soothe tired, partied-out eyes, and get a caffeine-like jolt at the same time.

The drops come in three strengths, Cool, Ice (which also soothes itch, irritation and burning), and their newest one, Arctic, which administers the highest level of their signature menthol-like "cooling sensation" felt when the drops hit your eyes.

Yup. Menthol-like drops. For your eyes. Sounds insane, but actually doesn't sear your retina like you'd think. And it's that ingredient that gives the "jolt" users call eye-drenaline. (And why it became a hit on the college and club scenes.)

We brought a bottle of Cool along on our Vegas trip a couple of weeks ago. We had one of those No-way-I'm-trying-it-YOU-try-it arguments, along with assorted questioning of manhood and testosterone levels, before one guy grabbed the bottle and tried a couple of drops. And that was it. We were all hooked for the rest of the weekend. We may have drank ourselves blind, but our eyes didn't show it. Not know how the stronger Arctic would have gone over, but like anything, once you build up a tolerance, you have to go for the stronger stuff.

$6.99 at most major drug stores.
