File:Focus in an eye.svg

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



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.

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.
