Retina

• What are the two main types of light receptors in the retina?

  Rods and cones
• Why are rods more useful than cones in dim light?


  Because rods are more sensitive to light
• How many different types of cone cells are there?

  Three
• What is the function of cone cells in the retina?

  They produce color vision
• What is the role of the retina in the eye?


  • Receives light that the lens has focused
  • Contains light receptors (rods and cones)
  • Converts light into neural signals for the brain
• How do rods and cones differ in function?


  • Rods:
  • More sensitive to light
  • Useful for dim light vision
  • Cones:
  • Responsible for color vision
  • Function best in bright light
