New Material For Fast-Change Sunglasses, Data Storage

Posted by kdawson on from the epileptics-need-not-apply dept.

sciencehabit writes "'Researchers have developed a material that almost instantaneously (30 ms) changes from clear to dark blue when exposed to ultraviolet light, and it just as quickly reverts to clear when the light is turned off. The new material, one of a class called photochromics, could be useful in optical data storage as well as in super-fancy sunglasses.'" A comment to the article notes some of the potential dangers of quick-change sunglasses.

    Of course there might be missing data from the article, but they should explain a bit more.

    That part was written in photochromic ink, you need to get a copy of the original publication and expose it to UV light in order to find out those details.

      Those would be useful too, and actually a lot more feasible with current technology. Just add a camera, a microprocessor running OCR, and a perl parser -- and turn the glasses opaque the moment the parser finds legal perl code. This could save millions of young programmers from brain damage. The only problem is to create software that can distinguish between perl code and random OCR errors.

      I'd prefer ones that filtered out COBOL or FORTRAN myself.

    Although, since I always end up losing the sunglasses part within a year, I'm considering just lashing out and getting prescription sunglasses.

    Been there, done that. I lost the prescription sunglasses. Three times. I decided that I just have to squint.
