Opalescent
Definition:
(a.) Reflecting a milky or pearly light from the interior; having an opaline play of colors.
Example Sentences:
(1) Among both exposed and non-exposed aged over 45, there were no significant differences with regard to the characteristics of lens opacities--prevalence (19 in the 21 exposed; 10 in the 16 non-exposed), distribution of the location, and importance and type (opalescence or discontinuous opacities).
