Optometry Vocabulary
Accommodation Correct Answer-Focus: increase in optical power by
the eye in order to maintain a clear image as objects are moved closer
Albinism Correct Answer-Lack of pigment in eyes, skin, and hair. Can
occur just in the eyes (ocular albinism)
Amblyopia Correct Answer-Decreased vision in eye(s) without
detectable health problem; commonly called "lazy eye"
Ametropia Correct Answer-The condition of having a refractive error
(myopia, hyperopia, astigmatism, or presbyopia)
Anisocoria Correct Answer-Unequal pupil size
Anisometropia Correct Answer-Unequal refractive errors in the eyes; at
least 1D difference
Asthenopia Correct Answer-Symptom of eyestrain; may also include
headache and browache
Astigmatism Correct Answer-Refractive error where refractive power is
not uniform in all directions; light rays are bent differently in one
meridian versus 90 degrees away; when written in Rx it is also called
"cylinder" or "cyl"
, Binocularity Correct Answer-The ability to use both eyes together;
results in depth perception/stereopsis; lack of results in double vision or
lack of depth perception/ stereopsis
Cataract Correct Answer-Condition where the crystalline lens becomes
cloudy or partially opaque; may be congenital, due to age (senile), or
trauma; lens may have to be surgically removed if vision is affected
Chalazion Correct Answer-Chronic inflamed gland in the eyelid; plural=
chalazia; commonly called "stye"
Congential Correct Answer-Describes a condition present since birth or
shortly after
Convergence insufficiency (CI) Correct Answer-Condition where one
has difficulty "crossing" eyes at near to fixate binocularly; can result in
double vision or eyestrain
Corneal Abrasion Correct Answer-Scraped area of corneal surface with
loss of superficial cells (epithelium); causes pain and photophobia; can
be abbreviated "k abrasion"
Corneal Laceration Correct Answer-Full thickness penetration of the
cornea; results in ruptured globe
