[edit] Description
English:
This diagram shows how light from afar is bent by the stretched lens to strike the retina, and how light from a closer source is bent even more sharply by the relaxed lens to strike the retina.
Italiano:
Questa immagine mostra come i raggi di luce provenienti da lontano siano deviati dal cristallino stirato per convergere sulla retina, e come i raggi provenienti da una sorgente più vicina siano deviati mggiormente dal cristallino rilassato per convergere sulla retina.
Svenska:
Ljus från ett avlägset föremål och ljuset från ett närbeläget föremål bringas i fokus genom att ögonlinsens kurvatur ändras med hjälp av ögats muskler.
