 BI/BO - Correct answer Cancels- subtract  Black numbers on lensometer power drum - Correct answer (+)  Red numbers on lensometer power drum - Correct answer (-)  When neutralizing, if you have a power that is in 1/8 diopters and need to subtract - Correct answer Add 1 to 1/8 amount  Ex. .12, you would need to subtract.  Focus sphere lines first, if cylinder lines focus first - Correct answer Rotate axis drum by 90°  When you have cylinder power, turn the power drum to - Correct answer The high plus, then gradually reduce power until one of the meridians comes into focus.  Where is the prism reference point (PRP) on progressives? - Correct answer centered directly between the two horizontal alignment engravings (or ink markings), usually about 2 to 4 mm below the fitting cross of the lens.  Where is the distance reference point (DRP) located on progressive lenses? - Correct answer generally located approximately 4 mm above the Fitting Point, providing an area completely free of the progressive power gradient.  Near reference point (NRP) - Correct answer represents the location on the surface that provides the full target Add power, which is the optimal location for verifying the Add power of the prescription. It is located at the center of the near checking circle ink marking.  Major Reference Point: (MRP) - Correct answer The point on a lens where the patient is provided the prescription as written by the doctor. If prism is not called for in the prescription then the lens OC and the MRP are the same.  Add power is - Correct answer The difference between the sphere and power in reading area of lens.  *subtract full reading amount from sph. value  Cylinder power is always used to determine if axis - Correct answer Meets ANSI standards  Binocular PD - Correct answer Total PD of both eyes together. From one pupil to the other pupil.  Monocular PD - Correct answer Individual PD of each eye. From pupil to bridge.
