  • identify the structures of the eye, including the iris, pupil, cornea, retina, and lens,
  • recall the functions of the different structures in the eye,
  • state that the image formed on the retina is inverted,
  • recall that light is detected by specialized cells called photoreceptors,
  • distinguish between the function of the rods and cones on the retina,
  • describe how the image is transmitted from the retina to the brain via the optic nerve.
