vitreous humor
the transparent, colorless mass of soft, gelatinous material which fills the eyeball behind
the lens:
1.42
the index of refraction of the crystalline lens is:
1.37
the cornea has an index of refraction of:
6
the extra-ocular muscles are inserted into the sclera and serve to rotate the eye in all
possible directions. There are _______________ of these muscles in each eye.
sclera and cornea
the fibrous tunic is comprised of the:
in the brain
fusion occurs:
the ciliary body
the aqueous fluid is continually being manufactured by:
accommodation
the ability of the eye to bring objects if varying distances to focus on the retina is known
as:
myopia
when accommodation is at rest, rays of light from a distant source come to focus in front
of the retina. this condition is known as:
hyperopia
when accommodation is at rest, rays of light from a distant source come to focus behind
the retina. this condition is known as:
optic nerve
impulses are carried from the retina to the brain along the:
the pupils constrict, the eyes converge, & the crystalline lens accommodates
while reading, or performing other near vision tasks:
forvea centralis
that area of the retina capable if perceiving the greatest amount of details is:
43 diopters
the average cornea has a refractive power of approximately:
the epithelium
that layer if the cornea which is highly regenerative is:
rods
Night vision is chiefly a function of the:
esophoria
A tendency of the visual axis to deviate inward when the eyes are in a position of the
rest is known as:
hyperopic
A "farsighted" eye is one that is:
,diplopia
The term used to indicate "double vision" is:
presbyopia
The condition in which the ability to accommodate for near vision ecomes inadequate
because of loss of elasticity of the crystalline lens is called:
amblyopia
When there is loss of vision without any apparent disease of the eye, it is known as:
astigmatism
A refractive error in which the rays of light do not come to a single point of focus is
called:
cataract
The condition in which the crystalline lens of the eye gradually loses its transparency
with consequent loss of visual acuity is known as:
glaucoma
An ocular disease as its primary characteristic a sustained increase in intraocular
pressure.
posterior chamber
The space between the back of the iris and the front of the lens which is filled with
aqueous is the:
hyperphoria
A tendency of one eye to deviate upward is:
cones
The photosensitive receptors of the retina which are responsible for sharp visual acuity
and color perception are the:
the stroma
The layer of the cornea which comprises ninety percent of its thickness is:
anisometropia
A condition in which the refractive error of one eye significantly differs from that of the
other and where both eyes have the same sign (i.e. both eyes are myopic or myperopic)
is known as:
compound hyperopic astigmatism
The refractive error which results in two points of focus falling behind the retina is:
irregular astigmatism
The refractive condition caused by a damaged cornea so that rays of light come to
many focal points on the retina is known as:
IN

produces prism base...
OUT
When the optical centers of a pair of minus lenses are positioned narrower than the PD,
it produces prism base...
DOWN
When a patient looks through a plus lens above the optical center, it produces prism
base...
DOWN
, When a patient looks through a minus lens below the optical center, it produces prism
base...
1.0

3.2
How much prism is induced 2 mm away from the optical center of a +16.00 diopter
lens?
0.9 BASE OUT
came in with the optical centers positioned 61 mm apart. The work order indicates the
patient's PD measures 64 mm and the prescription calls fro a -3.00 spheres in each
eye. How much total prism is induced and in which direction is the base?
1.45 BASE OUT
A patient's prescription calls for OD: +4.75 OS: +2.50. The optical centers of the finished
spectacles are found to be positioned 4 mm too wide. How much total prism is induced
and in which direction is the base?
air
the index of refraction is lowest in:
toward the base
when parallel rays of light enter prism, the light is deviated:
39.37
one meter is equal to _______ inches.
200
two meters equal ______ centimeters.
dividing the speed of light in air by the speed of light in the material.
the index of refraction of any given transparent material can be determined by:
186,000 miles per second
the speed of light in air is approximately:
refraction
when the direction of light is deviated in the course of the passing from one transparent
medium to another it is known:
1.70
light travels through a certain transparent medium at the rate of approximately 109,412
miles per sec. the index of refraction of that medium is:
1 prism diopter
if a prism can displace an image one centimeter at a distance of one meter, it is said to
have a power of:
wavelength
the distance between the crest of two waves is called the:
-20 cm
the focal length of a -5.00 diopter lens is:
base up prism
decentering a plus lens upward will result in:
corpuscular
