* non-elastic (it has the same constant refractory index)

* consists of high amounts of collagen fibers

* only organ transplanted from one individual to another without rejection

* for light refraction (light bending),(most important. feature regarding refraction)

* cornea and lens are involved with refraction

o the lens is not part of any tunic, because of the variable elastic change (it is elastic) hence the refractive index can change, the lens is also avascular

* non-elastic (therefore part of the tunic)

* anchors extrinsic eye muscles LR6[SO4]3

* the optic nerve, CN II , pierces the sclera in the back of the eye creating a blind spot (where there is no sight) = optic disc

* perioptic nerve exits out of the eye where the optic disc / blind spot is located

* the optic disc lacks photoreceptors: rods and cones

* visible colored portion of our eye

2. myopia - nearsighted, image converges in front of retina instead of striking the retina, problem is fixed using a concave lens

* the rods become active and the cones become inactivated

d) pupil - pin point structure that allows for light to enter the lens

* macula lutea - found lateral to the optic disc and are oval in structure
