Description
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.
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.
Ljus från ett avlägset föremål och ljuset från ett närbeläget föremål bringas i fokus genom att ögonlinsens kurvatur ändras med hjälp av ögats muskler.

The source of information for its creation (aside from general knowledge) was en:Image:Focus in an eye2.png by en:User:Fastfission, in turn based on en:Image:Focus in an eye.png by en:User:Theresa Knott.
