Cones are specialized receptor cells in the retina of the eye that are responsible for the perception of color and visual acuity, or sharpness of vision. They are concentrated in the fovea, the central region of the retina responsible for high-resolution vision. While rods play a key role in night vision and in detecting objects outside the main focus of vision, cones are not involved in these functions. Additionally, cones are not thin or cylindrical in shape, but rather are shaped like tapered cylinders or cones.
