Researchers at Johns Hopkins University have discovered a new cellular mechanism behind how humans develop sharp, high-acuity vision.
Using lab-grown retinal organoids, the team identified how the eye populates the foveola with the specific light-sensing cells needed for clear vision. Foveola is the tiny central region responsible for sharp, high-definition vision.
It was discovered that sharp human vision is formed during fetal development through a dynamic interplay between a vitamin A derivative (retinoic acid) and thyroid hormones.

Very interesting but if there is only red+green cells in the foveola how can we still perceive blue there?
