Motorized Polarized Sunglasses

 No glare for your stare.

These are glasses with round polarized lenses that rotate at 60hz. This allows the polarized lens to reject all glare.

It's powered by a very small something something.

       Uh, I think they'd reduce all glare by something like 1 over root-2 or 1/pi or somesuch. To put it another way, they'd let all glare through for much of the time.   

       What you really want is a pair of crossed polaroids rotating at maybe 2000rpm. That way, they'd definitely block all glare and would also be self-cleaning.

       The gyroscopic effects would cause you to fall over when walking round corners.

Perhaps slightly more useful would be auto-adjusting polarised glasses. These would be made of ordinary polarised glass. Either the glasses would detect the predominant angle of polarised light and rotate the lenses to match this, or the glasses would be rotated to minimise the light intensity received through the glasses (which gets the same effect).

       It would be quite useful if the human eye contained a polarising lens. The lenses of the Cayman Islands Pond Gecko are strongly polarising, and can be rotated by muscles in the eye. The gecko supposedly uses this as a means to detect the position of the sun on overcast days, to help guide its bi- annual migration.

       // 60hz //   

       3600 rpm ? [hippo] is quite right , there will definitely be gyroscopic effects to consider.   

       The obvious power source is photovoltaic ...   

       If the lenses are slotted, or finned round the edge, the spinning could also generate a pleasant breeze onto the wearer's face.

       Erm, contra-rotating lenses might cut down on the falling over bit?   

       Later edit: Thinking about it, it's probably easiest just to ask some Eskimo, they have several millennia experience of Polar-ized light.   

       Aha ha ha ha ....ahem.

       They actually would, though. Glare off of ice, water, etc. is polarized; that's why polarized sunglasses block it more than other light.
