Purkinje phenomenon

Pur·kin·je phe·nom·e·non

(pŭr-kin'jē), in the light-adapted eye, the region of maximal brightness is in the yellow; in the dark-adapted eye, the region of maximal brightness is in the green. Synonym(s): Purkinje effect, Purkinje shift

Pur·kin·je phe·nom·e·non

(pĕr-kin'jē fĕ-nom'ĕ-non) In the light-adapted eye, the region of maximal brightness is in the yellow; in the dark-adapted eye, the region of maximal brightness is in the green.

Purkinje phenomenon

The adjustment of the pupil of the eye to light intensity. When the eye adapts from light to dark conditions, the maximum pupillary movement is caused by green instead of yellow light. Synonym: pupillomotor reflexSee also: Purkinje, Johannes E. von
