Smart Sunglasses

Posted by samzenpus on from the so-I-can-watch-you-weave-in-real-time dept.

"Many readers have submitted this story of chemists at the University of Washington who have made glasses with lenses that can be transparent or dark, in shades of yellow, green, or purple, all at the push of a button. The glasses will let the wearer instantly change the color of their lenses to virtually any hue by tuning a tiny electronic knob in the frame."

  1. how about polarization by Blue+Shifted · · Score: 5, Interesting

    i frequently use polarized glasses to examine lcd screens for defects; it would be nice to change the angle of polarization without having to tilt my head at odd angles. also, when i change the angle, i can see through many different reflections.

      If you're doing this often enough, as you say, why don't you buy a linear polarizer? Here is a relatively cheap one. Much better ones can be had for more money. You can also use circular polarizing films to block reflected glares.

      If you drive with horizontally polarized sunglasses, you cut the glare from the road, but still get glare from the windshield. If you switch to vertical, you cut the glare from the windshield, but not the glare from the road. I don't want to see any reflected light.

      You should try wearing a larger pair of horizontally polarized sunglasses on top of a normal pair of vertically polarized sunglasses. That will accomplish your goal of not seeing any reflected light.

    What is this, 60's Star Trek? I want it to respond to my thoughts or at least memorize my preferences somehow. Buttons and Knobs. Really.

    Button-pushing is for weenies. Glasses that go black all by themselves at the first sign of danger--that's where it's at!

    I would buy these in an instant! I commute on a motorcycle and often times I leave in the morning. Unless it's cloudy i have to put on my sunglasses before the sun is even up. Then I ride north with darkened vision. But I have no choice because later I have to ride into the sun as it's rising. Impossible to safely do without the shades. Wearing a helmet, even with a flip up face-mask, it takes too long (and again, is unsafe) to fumble with putting on shades while on the bike. With these, I could easily turn a knob while at a traffic light. I just hope they put the knob where I can get to with with the helmet on, and while wearing gloves. Hell if they just made helmet visors that'd be even better!

  6. Nice! by Dr.+Eggman · · Score: 5, Funny

    But I'd rather have contact lens that change colors everytime I blink. It'd look really cool, but it'd probably be real distracting to people and retnal scans.

    The only truly smart sunglasses will be able to skitter off of my seat before I sit down on them. That, and when to fold in poker.

  8. Sunglasses? Colors? Pfft. by straponego · · Score: 5, Funny

    I want mirrored contacts. When somebody takes a flash photo of me it'll look like my head is exploding. Don't ask why I want that, I just... do.

  9. Colorblindness aid? by ereshiere · · Score: 5, Interesting

    I've got red-green colorblindness (green traffic lights look white, reds look darker than other colors, brown looks like both green and red, etc.). Will this help people like me in any way?

    Only yellow, green, or purple? No rose colored glasses? FTA:

    Chemists at the University of Washington in Seattle say they are developing 'smart' sunglasses that will let the wearer instantly change the color of their lenses to virtually any hue of the rainbow. So, whether you like your lenses clear, red, green, blue or purple, virtually any color could be obtained instantly by tuning a tiny electronic knob in the frame, the researchers said in a release. Unlike you, I read [part of] TA. I must be new here...

    Aren't there yellow glasses for people with bad night vision that reduce glare?

    Yup. I've got a pair of those. AFAIK my night vision is okay, but headlight glare annoys me; driving with these glasses is a lot less tiring. I also use them during dusk/dawn and in bad weather: they decrease contrast, making dark areas more visible.
