Cornea, Retina, Iris, Ciliary muscles are all parts of the eye.

  • Cornea: It is located at the front of the eye and prevents the light from reflecting back.

  • Iris: It contains the radial muscle to widen and circular muscle to constrict the pupil to regulate the amount of light entering the lens.

  • Retina: The retina is sensitive to light and contains two types of cells, the cone cells and the rod cells, which respond to bright and dim light.

  • Ciliary muscles: These muscles on contraction and relaxation change the shape of the lens for viewing objects at different distances.
