Cone cell

Cone cells, or cones, are a type of neuron (nerve cell) in the retina of the human eye.

  • Cone cells are cone-shaped whilst rod cells are rod-shaped.
  • Cone cells are responsible for colour vision and function best in bright light, as opposed to rod cells, which work better in dim light.
  • Cone cells are most concentrated towards the macula and densely packed in the fovea centralis, but reduce in number towards the periphery of the retina.
  • There are believed to be around six million cone cells in the human retina.
