Abstract
An eye-property monitoring system and method for performing the steps of (1) illuminating the eye from at least one light source whose wavelength interacts with internal eye properties in an optically active manner, (2) controlling, to make known and stable, the operating-power/light-output level of the source, (3) by such illuminating, producing light-source eye reflections including (a) multiple internal reflections within the outer structure of the eye, and (b) linked with those internal reflections at least one resulting outbound reflection, (4) monitoring the outbound-reflection to detect therein the reflection level associated with the at least one source, and (5) associating such detected reflection level as an indication of certain eye properties, such as aqueous glucose concentration.
