Eyes & Sight

• Structure C

  Cornea : allows light to enter and helps bend light

  
• Structure E

  Iris : controls the size of pupil and amount of light entering

  
• Structure A

  Water-like liquid ( Front ) /

  Jelly-like liquid ( Back ) :

  keeps shape of eyeball

  
• Structure B

  Lens : bends light and focuses it onto the retina

  
• Structure D

  Pupil : allows light to enter

  
• Structure F

  Sclera : protects the eyeball and keeps its shape

  
• Structure G

  Optic Nerve : carries signals to the brain

  
• Structure H

  Retina : contains light receptors to detect light and produce signals

  Cones for color, Rods for black and white

  
• Structure I

  Blind Spot : where optic nerve leaves retina

  no light receptors so it doesn't detect light

  
• Structure J

  Yellow Spot : central point of the retina

  most light receptors so it gives the clearest vision

  
• Structure K

  Muscles : change the shape of the lens for focusing
