Tears
-Consists of three layers:
*Lipoid
-Aqueous
-Mucoid
Optical Nerve
-Cranial Nerve II
-Transmits impulses from the retina to the occipital lobe
Myopia
-Near-sightedness: image is focused in front of the retina
-Laser surgery best for this type of refractive error
Hyperopia
-Far sightedness: image is focused in back of retina
Astigmatism
-A condition that occurs when the front surface of the eye (the cornea) is slightly irregular in shape. This irregular shape prevents light from focusing properly on the back of the eye (the retina). As a result, vision may be blurred at all distances.

Tears
-Consist of three layers
*Lipoid
*Aqueous
*Mucoid

-6-12 weeks for vision to return
Retinal Detachment
-Refers to seperation of the retinal pigment epithelium (RPE) from the sensory layer
-A tear occurs in the sensory retina and allows liquid vitreous to seep through the sensory retina and cuase detachement
