COSTCO ABO Optical Exam With Complete Solutions
100% Correct
optical centre of a lens
a point in a lens through which the optical axis passes without deviation
base in prism
children with convergence problems are often prescribed
optical images cross @
the optic chiasm
meridional power
the optic cross is a graphical presentation of a lens which illustrates
vertical imbalance
bicentric grinding is often used to correct
circumference
"c" in the box method refers to
prism axis indicator
the measurement of prism axis to be found in a vertometer or lensometer
near
, if the pd is measured when the patient is focusing 16 inches in front of the eyes
Added power
Progressive lenses wearer experiencing accommodation problems could be aided with
the addition of what to rx
Left temple in
most ideal frame adjustment when the left lens is positioned closer to the patients face
than the right lens
Hyperphoria
tendency of one eye to deviate upward from its normal position
Esophoria
Inward turning of the eye
Exophoria
eye turning outward
hypophoria
tendency of one eye to deviate downward from normal position
1/3 diopter
prism tolerance for a mounted lens in vertical meridian
advanced presbyope
higher add powers are most commonly prescribed when pt has
