"Expanding Human Vision: The Promise of Lab-Grown Retinas and Enhanced Color Perception"

A new study using lab-grown human retinas has revealed that the ability to see red and green colors is determined by levels of a molecule derived from vitamin A called retinoic acid. The research suggests that this molecule plays a crucial role in determining the ratio of red to green cones in the human eye, impacting color vision. The study sheds light on the diversity of human vision and its genetic underpinnings, offering insights into what makes human vision unique.
