According to my eye doctor, this type of exercise can be good for the eyes.
Our eyes are usually neglected and should be exercised like the rest of
our bodies. Many of us, including you, probably spend too much time in
front of a computer screen. If you are going to do so, this kind of activity
may occasionally be good for you. If you feel a little strain, that's fine.
If you feel a lot of strain, bookmark the page and come back to it at another
time. Also, visit a site that talks about ergonomics.
One noted exception to the above: If you have been cross-eyed in the
past, it is not a good idea to view stereo images using the free-fusion
approach. Viewing through a viewer or on a screen, such as described in
my section on displaying images
is preferred. Viewing the images on the computer screen may cause you problems.
Enjoy the pictures...
