|
protective shield; maintains the shape of the eye; white of the eye
|
|
cornea
|
transparent front part of the sclera
|
|
choroid
|
opaque middle layer of the eyeball
Provides blood supply for the eye |
|
iris
|
colored circle (muscle) of the eye; some are brown, some blue, some hazel
|
|
pupil
|
opening in the eye, where light enters, regulates the amount of light entering the eye.
|
|
lens
|
located behind the pupil and iris; for refraction (bending light rays)
|
|
ciliary muscles
|
alter the shape of the lens
|
|
retina
|
innermost layer of the eye; has nerve endings that are responsible for the reception and transmission of light impulses
|
|
optic nerve
|
carries the nerve impulses from the eye to the brain
|
|
optic disc
|
where the optic nerve and blood vessels of the eye enter the eyeball; also calles blind spot because it doesn't have rods and cones
|
|
macula lutea
|
area in the center of the retina
|
|
anterior chamber
|
behind the cornea and in front of the iris
|
|
posterior chamber
|
located between the iris and the lens
|
|
aqueous humor
|
watery substance; provides nourishment for the lens and the cornea. The body continuously produces this.
|
|
Glaucoma results from
|
aqueous humor that fails to drain from the eye like it should
|
|
vitreous humor
|
jelly-like substance; body does not continuously produce this. along with the aqueous humor helps with refraction
|
|
accommodation
|
you can see up close and far away with the lens we were born with

farsightedness
|
|
presbyopia
|
farsightedness caused by the aging process
|
|
astigmatism
|
the cornea or lens has a defective curvature
|
|
glaucoma
|
Takes away the peripheral vision is increased intraocular pressure because the aqueous humor not draining out
