Sunglasses are meant to block out bright sources of light, but how many actually do so. That is, how many actively seek out sources of glare and block them out? Sure, there are those tint-shifting lenses that transition from sunglasses to clear lenses when the wearer moves from brighter to darker environments, but upstart company Dynamic Eye wants to up the ante by creating glasses that actually seek out the source of glare and darken the lens only where necessary.
Now, before you judge the clunky concept above, consider the technology here; the lenses are actually LCDs that rely on an embedded camera to locate sources of glare like the sun. Even if there are multiple sources – say, the sun and the reflection of the sun off water or snow – the LCD lenses place a dark spot over the glare. You move, the glare moves, the dark spots move with it (see the video below). The rest of the lenses stay relatively lightly tinted so you can see what you're doing.
It's pretty smart, though we're not sure glasses are really where this technology might be best deployed. We tend to move our heads a lot, even when we're sitting still, and a bunch of dark spots moving around our fields of visions might induce headaches. But figure out how to use this to blunt the intensity of glare on, say, automobile windshields and the like, and Dynamic Eye might really be onto something.
Either way, it's a pretty neat idea though nowhere near production. If you're diabolical plans call for blotting out the sun in the foreseeable future, navigate on over to Kickstarter and drop Dynamic Eye a donation. Four hundred bucks gets you one of the first pairs off the assembly line, if and when they go into production.
I can see professional football players would love a pair of these. How many times have we seen NFL players lose sight of the ball over the glare of the sun? Too many times to count!
I've been thinking for years that they should have some sort of technology like this for car windshields. I hope they can perfect/integrate this down the road.
uh? like gizmowiz said sports.
Jcbullen's idea ain't bad, but is probably easier to do this in the glasses... so: driving a car? walking? Military? Swat? Airline pilots? Colonial Viper pilots? the list is endless and for non-vampires too, just see how regular people might enjoy these at night: for opposing traffic's headlights, bright lights that ruin peoples night vision...
Clearly this amazing design is not complete: finer res/more pixels would vastly improve it, the dark spot should be have darkness scale too (with maximum darkness designed for the sun and lower darkness scales for other bright sources like highway headlights, that street light at the end of the block, more distant stars...), the dark spot should be round (or the shape of the light source (eg it may be a line when sun is reflecting off a lake)), faster response time (though I think it doesn't need vast improvement in that category), the base tint might be adjustable too (so you can take them snowboarding during the day and crank the base tint up to max and still use it to block the headlights of opposing traffic on the way home with the base tint turned down to zero).
Also Clay thinks "and a bunch of dark spots moving around our fields of visions might induce headaches" I imagine when it is finished it will not have that effect, as all the tech updates are integrated into a refined marketable product, the glass will have a smoother transition and u won't see any black spots, as the entirety of every "spot" would perfectly align with every extreme light source making no spots visible.
I can't wait.
This sounds pretty gimmicky as applied to sunglasses.
However, a better use for this technology would be at football or baseball games -- attached to the front of camera lenses. You ever noticed how the sunlit part of the field gets washed out when the camera adjusts to the action in the shadows? Or, how the field in shadow darkens far too much when they adjust for action in the sun?
This is where the money is for this technology folks!
(You heard it here first.)
I say utilize it for cameras to reduce glare. I wouldn't mind an all in one lens that:
a, has the blotting feature,
b, be used in 3d videos, and
c, be adjustable in color tint and blotting strength.
(d, convert into helmet)
(e, shoot laser beams)
(um... :\ )
I've been brainsweating on how to do this for my motorcylce and snowmobile helmets for a while now. Go, man, go. Make a visor available for arai helmets and I'll buy a couple. So long as they can be made fog proof.
Great idea, but here's the real problem they need to solve: A person wearing their sunglasses up close next to their eyes is going to require the glare-blocking LCD spots to be in a different position than someone wearing their sunglasses further down on their nose. So the glasses need to be smart enough to know where your eyes are in relation to the lenses. Probably not too big a problem for sunglasses, but for something like an automobile windshield, where the driver is constantly turning his head and rocking out to a tune on the radio, the glare-blocking spots would have to be moved around a lot in order to be directly in between the source of glare and the eyes. And also a nearby glare source would require the LCD spots to be in a slightly different position for each eye, not a problem for the sunglasses, but what would that look like on an auto windshield?
very neat idea :)
bright spots can induce headaches sure, but i don't really see how dark spots (covering the bright ones) would..
sunglasses are easier to implement i think since ur eyes will be in the same place for the majority of the time, but simply combining this with the eye-tracking tech already in place in a lot of vehicles would be an easy way to cut back on road glare (as many of you have noted) ;)
I've been thinking for years of something like this to go in vehicle windshields, but never had the money or resources to develop it. Props to that guy for finally being the one to do something similar!
@HBillyRufus: It would be a little more complex and require more computation for a car windshield, but it's still quite doable. 2 cameras on the inside of the vehicle would monitor where the driver's eyes are. The onboard computer uses the stereo video to calculate the location of the driver's eyes in 3D space. At the same time, 2 cameras on the outside of the vehicle monitor bright spots, calculating their approximate coordinates. Then, the computer calculates a line between the two sets of coordinates and darkens the windshield around the area that the line intersects it, large enough to cast a shadow on their whole face.
Certainly a more complex system than for the glasses, but I could see it working very well.
this video sucks. No glasses in action, just a bunch of talking. It sounds like they haven't even made any yet. I wouldn't drop $400 on something they don't even have yet, especially with the way companies rise one day and tank the next.
Hey guys there's a company called alphamicron that have working products that are better than this. They also have visor inserts for motorcycles, snowboard goggles, and a full auto tint glasses coming soon, and are currently designing a insert that works for arai helmets
