c) this relaxes accommodation the patient to accommodate during distance
d) this stimulates accommodation testing. Light rays are nearly parallel at 20 feet,
so this was selected as a practical testing
distance.

numbers, symbols, or pictures) are
known as:
a) Snellens
b) optotypes

d) Allens
The top number (numerator) of c) The upper number (numerator) of the
the notation "20/20" means: standard "20/20" fraction stands for the test
a) the size of the optotypes distance.
b) the vision of a "normal" eye
c) the test distance
d) the patient's acuity
The bottom number b) The test distance is the standard 20 feet (the
(denominator) of the notation numerator). The denominator (bottom number)
"20/20" means: is the distance at which someone with normal
a) the normal eye can recognize vision can correctly recognize optotypes of
optotypes of this size from 2 feet this size. Thus, 20/20 denotes an eye that can
away see "normally," or what the normal eye should
b) the normal eye can recognize see from 20 feet away.
optotypes of this size from 20 feet
away
c) an acuity quotient of 1%
d) the testing distance is 1 foot
, A visual acuity of 20/20 or better d) Visual acuity tests the cone cells, not the
(corrected or uncorrected) rods.

except:
a) the media are clear
b) the optic nerve is functioning
properly
c) the fovea is being used for
fixation
d) the rod cells are functioning
normally
A person with 20/80 vision: b) The person with 20/80 vision sees at 20 feet
a) sees at 80 feet what the normal (the test distance, numerator) what a person
eye can see at 20 feet with normal vision can see from 80 feet away
b) sees at 20 feet what the normal (the denominator). Thus, the patient with 20/80
eye can see at 80 feet vision has to be 60 feet closer to the optotype
c) can see better than 20/20 than someone with normal vision, before he or
d) has a refractive error she can correctly identify it. The patient may
have a refractive error, but subnormal vision
can have many causes.
The patient's acuity is noted to be d) The numerator (top number) always refers to
10/40. This indicates: test distance; thus, 10/40 indicates a test
a) a test distance that is one-fourth distance of 10 feet.
