What are the cones in the retina responsible for?

The cones in the retina are specialized photoreceptor cells that play a crucial role in color vision. They are concentrated in the fovea, the central part of the retina, where they are particularly effective at detecting fine details and different colors in light. There are three types of cone cells, each sensitive to different wavelengths of light corresponding to the colors red, green, and blue. This trichromatic system allows us to perceive a wide range of colors by combining the signals from these three types of cones.

In addition to color detection, cones also contribute to central vision and visual acuity, particularly in well-lit conditions. However, their primary and most significant function is related to color vision. This differentiates them from rods, which are more sensitive to low light levels but do not convey color information, and are primarily responsible for peripheral and night vision.
