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.
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.

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.
