By utilizing existing data on refractive indices of the ocular media I developed methods to convert refractive indices within the visible spectrum. The calculated values have approximately the same accuracy as measurements with standard methods. An independent test confirmed the validity of the formulas.

Deviation of Calculated Refractive Indices from Measurements for the Frog Rana pipiens
N and K in Eq. (2) were determined from n(440) and n(650).
The indices were converted from 590 nm to 440, 486, and 650 nm.
The indices were converted between all possible pairs (n = 12) of wavelengths.

Refractive Indices in the Lens of a Harbor Porpoise (Phocoena phocoena)a
Indices were measured by Matthiessen,6 presumably at 590 nm, and converted to 390 and 640 nm with Eq. (13).
Distance of the sample site from the center of the lens.
