Classification: CPC G | IPC G

Claim 2:
3. The method according to claim 1, further comprising:
measuring a third intensity of radiation reflected from a secondary location contemporaneously with measuring the first intensity, wherein the at least one region is different than the secondary location
measuring a fourth intensity of radiation reflected from the secondary location contemporaneously with measuring the second intensity;
comparing the third intensity to the fourth intensity to determine a change in intensity of radiation between times of measurement of the first and third intensities and the second and fourth intensities; and
compensating for the change in intensity of radiation between times of measurement of the first and third intensities and the second and fourth intensities in the calculation of the transmittance of electromagnetic radiation through the contact lens using the comparison between the third and fourth intensities.
