On this page we will look at the same scene through the eyes of four different people, one with normal vision, and the others with different vision problems. This should give you a feel for how these people see the world.
Normal
![]()
This is the scene as viewed through normal eyes. Things near and far appear in focus.
Nearsightedness
This is the scene through nearsighted
eyes. Close up objects like the chairs are in focus, while objects
far away like the islands are blurry.
Farsightedness
This is the scene through farsighted
eyes. Objects far away like the islands are in focus, but close up
objects, like the chairs are blurry.
Astigmatism
This is the scene through astigmatic
eyes. This is like a combination of both near and farsightedness,
making all objects blurry.
