Practice being drunk?

Kind of . . . one of the talk shows here in Japan showed a new product. Available in two different styles, one for daylight and one for nighttime. These were goggles, with lenses that have been designed to give some of the effect of being intoxicated. For example, one of the guests put on the daylight version and tried to walk a straight line along a red line they had on the floor, then sit down. He was quite surprised to find himself wobbling, crisscrossing, and then trying to sit down a bit in front and off to the side of the chair. Views through a single lens showed some blurring, but I suspect part of the trick is having two lenses with somewhat different focus?

The daylight ones were clear, while the nighttime ones were dark, producing night even in the well-lit TV studio.

It's an interesting concept. Give yourself an opportunity to experience the loss of control and so forth while sober, so that maybe you'll decide to avoid driving and other dangerous exercises after actually drinking.

Now if they can figure out a way to imitate the slowed reaction times . . .
