You can see them in 3D by sort of "staring" at them.
To view them they need to be about 4 to 5 1/2 inches wide. If your screen can't get them that size you may need to print them out.
You need to let your eyes wander, or diverge, as if you were looking at a distant star. At the same time your eyes need to focus on the screen. This can be done but it is something your eyes don't normally do and so therefore do not like to do. When you are there your brain should see something like this.
The center one should be in 3D. (Not this image of course)
If not you can build a stereoscope. They are rather simple, like this.
I had difficulty getting lenses of the right focal length so mine has a pair of lenses, and concave and a convex.
Once you master that you can try a simple version like this.
If you can see a 3D image with this then you should be able to see it on the screen without any aids.
Once you master that try this.
