What are the different Parts of an Eye?

Author: eric_galvao



Answer:

-Cornea: Simply Bends or Refracts the Light into the Eye] -Iris: Can control how much light comes into the Pupil [Hole in Middle] -Lens: Same job has as the Cornea, excepts it also Focuses the Light for the Cornea -Ciliary Body: This has Ciliary Muscles which are linked with the Suspensory Ligaments. These 2 pair up to be able to Alter the Shape of the Lens -Retina: This is the Light Sensitive Part. Full of Rods and Cones which are Receptors which detects light. -Rods: Better in Dim Light, but struggles with Colour -Cones: Better with Different Colours but cant deal with Dim Light -Optical Never: Takes the Impulses from the Receptors to the Brain
