Change a bifocal Rx to a single vision Rx - Add the bifocal power to the sphere powers. OD: -0.50 OS: -0.25-0.25x172 Add: +1.75 Turns into- OD: +1.25 OS: +1.50-0.25x172 Anisometropia - There is a difference of 3 diopters between both eyes; when the vision of the eyes differs by a large margin. Antimetropia - Refers to Rx's that differ in sign. Ex. OD: +0.25 OS: -0.75

Prentice Rule - (Power x distance in mm) /10 Cornea index of refraction - 1.37 Tear Film, Vitreous index of refraction - 1.33 Crystalline lens index of refraction - 1.42 Optical Standard index of refraction - 1.53 Crown Glass index of refraction - 1.523

If the wearer complains of the bifocal line being somewhat in his way when driving, the problem may be alleviated by decreasing the distance between pads. True or False - False If the wearer complains that the glasses feel snug but still slip down the nose, one likely cause is that: A. The frame is too small B. The bridge fit is tight C. Pressure is being applied by the temple shafts anterior to the ear. D. Pressure is being applied on the very tips of the temples. - Pressure is being ap...

Sclera - Tough, white outer coat of the eyeball myopia - nearsightedness; the condition in which parallel rays of light are brought into focus in front of the retina, rather than on it reflection - light that bounces back refraction - when the direction of light changes as it passes from one medium to another(bending of light)
