I wear glasses, and I've had these new ones for a month or two. I clean them and within minutes, sometimes, I must either clean them again or ignore the smears.

Why, with all the high-tech of 2006, can't someone invent self-cleaning glasses?

There have been glasses for sale for years, although not mass-marketed, probably due to high cost, which would replace a computer monitor!

These glasses, although I have not tried them, reportedly make it seem to the wearer that they are viewing a 60" monitor from 5 feet away or something.

Some news came out at one of the last trade shows a month ago or so that several competing firms will offer similar devices this year at much less cost, perhaps as low as a replacement monitor.

I like that idea. In fact, put the whole PC in there, along with software to track your eye movements. Then, say, a double eye-blink might act like a double mouse-click.

If the whole set-up has a mobile web connection, driving the car could be like using a heads-up-display (HUD) in a modern airplane. You wouldn't get lost, even in territory you've never visited, with a virtual map overlaying the reality outside the windshield! (I might get some real work done, even on the way to my job!)

There will soon be glasses which will NOT be the ground-glass-into-a-prescribed-lens which I currently wear daily. These will have tiny cameras looking into the eyeball, tracking what the eye is attempting to resolve.

Then, tiny electrical signals might warp the lens of the eye just enough, or perhaps with a direct connection to the optical nerve, the wearer could be allowed to perceive objects extremely close up in microscopic mode or extremely far away in telescopic mode.

Variations could be accomplished to suit the individual wearer, such as gothic folk might like to view the world in black and shades of gray.

Kaleidoscopic controls or other psychedelic light-show-type techniques might be commonplace! ("Tie-dye your visual world, today!")

I want some!
