Cones

Rod and cones, the photoreceptor cells of the retina

Cones are a type of photoreceptor cell in the retina. They give us our color vision. Cones are concentrated in the center of our retina in an area called the macula and help us see fine details.

Eye problems that can affect cones include:

  • Color blindness
  • Photokeratitis
  • Retinitis pigmentosa
  • Usher syndrome
