   The process by which the eye adjusts to bright light conditions, involving the constriction of the pupil and changes in retinal sensitivity.

   adaptation à la lumière

   • Light adaptation occurs quickly when you step from a dark room into sunlight.
   • The human eye undergoes light adaptation to reduce glare and improve vision.
   • After light adaptation, the cones in the retina become more active.
