File:Focus in an eye.svg

This vector image was created with Inkscape, and then manually edited.

[edit] Summary

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 maggiormente 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.

[edit] Licence, source, credits & technical notes

This diagram was hand-drawn in Inkscape and then tweaked in Notepad by User:Erin Silversmith. The right-hand eyeball is a clone of the other, and all the arrows are clones of the top-left one. Both the eyeballs and the lenses have translucent black fills.

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.
