NIGHT VISION DROPS

摘要

Seeing in the dark could soon be as easy as popping a pill or squeezing some drops into your eyes, thanks to some new science, an unusual deep-sea fish, and a plant pigment.rnIn 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 and identified it as chlorophyll. "That was weird," he says, "because chlorophyll is something you usually find in plants," where it gathers light energy for photosynthesis. The fish had somehow co-opted chlorophyll, most likely from bacteria in their food, and turned it into a vision enhancer.
