Human eye can see 'invisible' infrared light
In international team of researchers has found that under certain conditions, our eye can sense “invisible” infra-red light.
By using retinal cells of mice, humans and powerful lasers that emit pulses of infrared light, the team discovered that when laser light pulses rapidly and light-sensing cells in the retina sometimes get a double hit of infrared energy.
The research was initiated after scientists reported seeing occasional flashes of green light while working with an infra-red laser.
The team experimented with laser pulses of different durations that delivered the same total number of photons.
They found that the shorter the pulse, the more likely it was a person could see it.
Doctors may be able to stimulate components of the retina to know more about its structure and function in healthy eyes and individuals with retinal diseases by shining a pulsing, infrared laser into the eye.
