Sight Tricks

As a child I was shown a film by the Moody Bible Institute that was a science teaching tool.(Sense Perception  (Color, 1960) In it a man put on a pair of glasses that turned everything upside down. After some time the film told us that his brain corrected the image to where he could see everything right-side up again with the glasses still on. When he took his glasses off after the experiment was over his own vision saw everything upside down until a few days went by and his brain corrected his vision.

 Actually, according to experiments performed as long ago as 1896, if you wear such goggles for long enough, your brain will adapt and everything will appear right-side-up again.

 The point was that our brains were an incredible part of us. In another film by Moody the man drank some nuclear fluid while holding a Geiger counter in an outstretched hand. They timed how long it took for the Geiger counter to pick up on the radiation after he ingested the radiation. Looking back we all know that doing something like that can be dangerous to one's health...

Here is someone else experienced in viewing the world through glasses.

"Steve Mann (whom you might know for his having pioneered wearable computing as a grad student at MIT back in the 1990s) writes in IEEE Spectrum magazine about his decades of experience with computerized eyeware. His article warns that Google Glass hasn't been properly engineered to avoid creating disorientating effects and significant eyestrain. While it's hard to imagine that Google has missed something fundamental here, Mann convincingly describes why Google Glass users might experience serious problems. Quoting: 'The very first wearable computer system I put together showed me real-time video on a helmet-mounted display. The camera was situated close to one eye, but it didn’t have quite the same viewpoint. The slight misalignment seemed unimportant at the time, but it produced some strange and unpleasant results. And those troubling effects persisted long after I took the gear off. That’s because my brain had adjusted to an unnatural view, so it took a while to readjust to normal vision. ... Google Glass and several similarly configured systems now in development suffer from another problem I learned about 30 years ago that arises from the basic asymmetry of their designs, in which the wearer views the display through only one eye. These systems all contain lenses that make the display appear to hover in space, farther away than it really is. That’s because the human eye can’t focus on something that’s only a couple of centimeters away, so an optical correction is needed. But what Google and other companies are doing—using fixed-focus lenses to make the display appear farther away—is not good.'"
