Smart Sunglasses

"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."

So yet another reason for assholes to "wear their sunglasses at night" and be distracted about whilst they drive.

Aren't there yellow glasses for people with bad night vision that reduce glare? They're _supposed_ to be worn at night for safety reasons and I think from TFA, these glasses also go yellow. If the shade of yellow is right, people could use the same pair for day and night driving, which is pretty cool.

By the way, people who drive with sunglasses at night are not assholes, they are dickheads. There's a subtle distinction.

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...

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.
