accommodation (Acc)
process by which the eyes make adjustments to see objects at various distances
amblyopia
dullness of vision; reduced or dimness of vision; also called lazy eye
anisocoria
condition in which the pupils are unequal
astigmatism
defect in the refractive powers of the eye in which a ray of light is not focused on the retina but is spread over an area; it is due to a misshapen curvature of the cornea and lens
bifocal
pertaining to having two foci, as in bifocal glasses; one foci for near vision and another far vision
blepharoptosis
drooping of the upper eyelid(s)
cataract
opacity of the crystalline lens or its capsule; most often occurs in older adults

corneal
pertaining to the cornea

condition in which the eye or eyes turn inward; crossed eyes
exotropia (XT)
turning outward of one or both eyes
glaucoma
disease characterized by increased intraocular pressure (IOP)
hemianopia
inability (blindness) to see half of the field of vision
hyperopia (HT)
vision defect in which parallel rays come to a focus beyond the retina; farsightedness
intraocular
pertaining to within the eye

one who specializes in examining the eyes for refractive errors and providing appropriate corrective lenses; this person is NOT a physician but is trained and licensed as a doctor of optometry (OD)
photophobia
unusual intolerance to light
presbyopia
vision defect in which parallel rays come to a focus beyond the retina; occurs normally with aging; also called hyperopia (farsightedness)
pupillary
pertaining to the pupil
retinitis
inflammation of the retina
