How do you use the lensometer or lens clock for finding the refractive index of a lens?

The formula for calculating a lens' refractive power is as follows:
n = (D * R) + 1, where n = refractive power, D = optical power in diopter, and R = lens curvature radius.

A lens clock will give you an estimated optical power, d and from there you can work out the curvature radius by using the formula:
R = (0.53)/d.

A lensometer will give you the actual optical power, D.

Input the R and D into the first formula and you will get the lens' refractive index, n.
