Magic Spectacle

Bye bye bifocals, hello electronic spectacles
Traditional bifocals could become a thing of the past with the invention of electronic glasses that automatically adjust to let their wearer view objects at different distances.

Who knows what I'm doing here?


“ The spectacles, which are due to be launched in the US this year and the UK next year, use lenses that change their strength when a small electrical current passes through them.

A layer of liquid crystal sandwiched inside each lens alters its refractive properties according to the current applied, adapting the focal length according to where the wearer is looking.

This erstwhile optician is agog!

Something else that needs batteries or charged up.
No thanks, I'll stick with my plain-vanilla reading glasses that always work, and don't need to run on electricity.

Actually, I'll be buying the new spectacles. I'm so in need of bifocals now, it's naught but pride and inertia keeping me from the doctor. Make it a new toy, and I line up today.

As to what you're doing there, that's too yellow and not explosive enough to be an ether fire. Your grinder there sparked, and lit up some solvent, isopropanol perhaps? The cig is a nice touch, happen often did it?

I wonder if this could be adapted to fine-tune the sight picture of a rifle scope.

So you're driving down the road at 80mph and the battery in your glasses dies--- changing the focus from the road to only 18inches--- while the guy up ahead of you taps on his brakes and slows down to 55.

What could go wrong??????

That's a Shuron 360B lens grinder. The glass lens blank is cut by a diamond wheel cooled by oil. If you pull it through too quickly the wheel heats up and ignites the oil. Loud bang. It's a no-no so it only happens by accident. Ahem.
