'Laser vision' offers new insights

[Lincoln]

A system has been developed that projects lasers onto the retina, allowing users to view images on top of their normal field of vision.

It could allow surgeons to get a bird's eye view of the innards of a patient, offer military units in the field a view of the entire battlefield and provide mechanics with a simulation of the inside of a car's engine.Submitted by: Norge

It would have to be a very weak beam projection to not damage eye or leave "sunspot" inverse echoing if used for other than TINY amounts of time. When I had laser meld surgery to retinal tissue, a fairly strong laser beam, argon type, had to be used. 30 short intense bursts left me mostly blind in same eye for three hours and I had fading echoes for another half day. where laser had impinged on vision, things were dark to black. The 3-D idea on eye is great, except for laser damage with direct projection.
