Eye proteins detect a redder red than you've ever seen

摘要

We all see red every now and again, but Imagine seeing red beyond red. The structure of a protein normally found in the human eye has been altered so that It absorbs a type of red light that we cannot normally see. This could. In theory, one day give us the ability to see reds that are currently invisible to us. Our colour vision depends on proteins that contain chromophores - chemicals which absorb different wavelengths of light.
