Forget the Goggles

Sunday, September 20th, 2009

It may be a bit soon to say, forget the goggles, but it does look like chlorophyll eye drops might give night vision:

In the 1990s, marine biologist Ron Douglas of City University London discovered that, unlike other deep-sea fish, the dragonfish Malacosteus niger can perceive red light. Douglas was surprised when he isolated the chemical responsible for absorbing red: It was chlorophyll. “That was weird,” he says. The fish had somehow co-opted chlorophyll, most likely from bacteria in their food, and turned it into a vision enhancer.

In 2004, Ilyas Washington, an ophthalmic scientist at Columbia University Medical Center, came across Douglas’s findings. Washington knew that the mechanisms involved in vision tend to be similar throughout the animal kingdom, so he wondered whether chlorophyll could also enhance the vision of other animals, including humans. His latest experiments in mice and rabbits suggest that administering chlorophyll to the eyes can double their ability to see in low light. The pigment absorbs hues of red light that are normally invisible in dim conditions. That information is then transmitted to the brain, allowing enhanced vision.
