Scientists modified the eyes of 5 humans to see an unprecedented new color

Get the Full StoryBy stimulating certain cones with extreme precision, scientists can help humans perceive a new color that defies all comparisons.

From the first time I saw Blade Runner and heard Rutger Hauer s Roy Batty describe C-beams glittering in the dark near the Tannh user Gate, I ve wondered what it would be like to see beyond the limits of human vision. What would it feel like to have eyes that could see what we can t normally see? I envied animals who can see light frequencies in the infrared and superheroes with X-ray vision that let them see like a NASA telescope. And today, I envy five regular human beings who, after having their eye cones temporarily rewired with a laser, were able to perceive a new color outside the typical range of the human eye.
