Single Vision Prescription With Prism

Progressive Prescription

If your prescription is like the following ones, you need to fill in information like the example below. (Note: there is no PD value in the prescription, but you need to fill in your PD value)
Sample 1, you just need to fill in the corresponding values.
Sample 2, you need to change +225 to +2.25, -150 to -1.50, -125 to -1.25, -50 to -0.50, and then fill in the corresponding values.
Sample 3, you need to use Near O.D. +0.75-Distance O.D.-1.50 or use Near O.S.+1.00- Distance O.S. -1.25 to get the ADD +2.25 value and then fill in the ADD blank

PS: the three different prescriptions get the same prescription lenses.

Sample 1 Sample 2 Sample 3

Other Information You Might Use When Filling In Prescription

OD stands for “oculus dexter,” or right eye.
OS stands for “oculus sinister,” or left eye.
if there is PL or DS in your prescription, it means the value should be 0.
The term PL (Plano) means there is no spherical correction in this eye.
DS stands for “diopter sphere”, which means there is no astigmatism correction for this eye.
You need to fill in information like the example below. (Note: there isn’t PD in the prescription, but you need fill in your PD measurement)
