innermost layer that perceives and transmits light to the optic nerve
cones
responds to bright light

extreme sensitivity to and discomfort from light
scotoma
blind spot in vision
scotophobia
fear of the dark
refractive errors
defects in the bending of light as it enters the eye, causing an improper focus on the retina

distorted vision caused by oblong curvature of the lens or cornea that prevents light rays from coming to a single focus on the retina
hyperopia
farsightedness
myopia
nearsightedness
presbyopia
impaired vision caused by old age
accomodation
ability of the eye to adjust focus on near objects

inflammation of the eyelid
blepharochalasis
baggy eyelid
dermatochalasis
baggy eyelid

ectropion
outward turning of the rim of the eyelid
entropion
inward turning of the rim of the eyelid
epiphora
abnormal overflow of tears caused by blockage of the lacrimal duct
glaucoma
disease of the eye characterized by increased intraocular pressur that results in damage to the optic nerve, producing defects in vision
