Tibbetts and his co-experimenter, Gabriel Licina, are solidly in between. The team spent six months reviewing previous studies to craft a nutritional protocol designed to modify their vision, bearing the mark of their backgrounds in human anatomy and molecular biology.
So the two began to study the literature on how to see in the infrared. Before the ubiquity of infrared goggles, military research projects dating back to the s tested infrared vision in rats. After six months of research, Tibbetts and Licina decided on a tactic: regular doses of a vitamin over a series of months with the aim of letting their eyes make sense of light in longer wavelengths. The rods and cones in our eyes allow us to see the range of colors that we do. A dietary compound called retinal, a form of vitamin A, binds to enormous proteins called opsins in the eye, which convert light into a chemical signal that your brain can interpret.
When a photon hits the retinal, a chemical reaction takes place at the end of the appropriate cone in your eye. The idea is that by shining a pulsing, infrared laser into the eye, doctors might be able to stimulate parts of the retina to learn more about its structure and function in healthy eyes and in people with retinal diseases such as macular degeneration.
The research was made possible, in part, by the Kefalov team's development of a tool that allowed the scientists to obtain light responses from retinal cells and photopigment molecules. That device already is commercially available and being used at several vision research centers around the world. Materials provided by Washington University in St. Original written by Jim Dryden.

Science News. Collaborators include scientists in Cleveland, Poland, Switzerland and Norway, The research was initiated after scientists on the research team reported seeing occasional flashes of green light while working with an infrared laser. Kefalov, Krzysztof Palczewski. Human infrared vision is triggered by two-photon chromophore isomerization. ScienceDaily, 1 December The human eye can detect the visible spectrum of the electromagnetic spectrum — a range of wavelengths between to nanometers.
But recently, researchers from Washington University in St. Louis discovered that contrary to prior beliefs, the human eye is in fact capable of seeing infrared light — but only under certain conditions. But the scientists found that if two photons of infrared light hit the same receptor one after another, it adds up to one photon of visible light, which was the green flash the researchers saw.
Though the heart is known as the strongest muscle in the body, your eyes are also extremely active when it comes to muscle movement. Within just one hour of reading a book, the eyes make up to 10, coordinating movements. The ability to repeat motions is also very strong in the eye. Facelift Surgery.
