+5.00 -2.00 x 095
out - correct answer the pupillary distance ground too wide for a plus Rx will result with this type of prism base
out - correct answer the pupillary distance ground too narrow for a minus rx will result with this type of prism base
base in and base in - correct answer this combination of prism is not a canceling situation
base up and base up - correct answer this combination of prism is not a compounding situation

saggital value or sag - correct answer an indictor of lens thickness
closet distance between lenses - correct answer DBL
"A" Box - correct answer measurement referring to the horizontal straight line between the farthest nasal and the farthest temporal point of a lens
reads base curves - correct answer not a function of the lensometer
reticle - correct answer the concentric circle configuration within the scope of the lensometer
front side - correct answer the bifocal add must be read with this side on the lens against the lens stop
binocular - correct answer the pd measurement which indicated the distance from the center of the pupil to the center of pupil
