blind spot

• small spot on back of retina - other eye compensates for this area
• transmits electrical signals from retina to the brain
• lens behind pupil; allows us to see objects near and far
• the hole where light enters into the eye

cornea

• a type of energy that travels as an electromagnetic wave
• Colored part of the eye that controls the amount of light entering the eye
• clear lens in front of eye
• transmits electrical signals from retina to the brain

iris

• clear lens in front of eye

• Colored part of the eye that controls the amount of light entering the eye

• lens behind the eye

• transmits electrical signals from retina to the brain
