Are you able to blur your vision whenever you like and for as long as you want, to switch from sharp to blur in a second at your own command?

this involves the conscious control of the ciliary muscles which are in charge of the auto focus of your vision. The talent involves neurosensory and neuromuscular pathways and controls.

 

I would like to know your opinion as I have been asking to several research institutes and it seems the ability is not really known, only few people can do it naturally did you know about this?

i can see blur in my own will for as long as i want and no i don't wear glasses or so.My Eyes are pretty good even tho i spent many hours in front of screen's on computer or on tv but still that doesn't mean that me or anyone else that can do that have some special ability it's just much easier than we thought the only thing you must do is to focus to something by controlling your eyes and there you have it

I would like to learn more about this 

Muscles tense or relax to change the shape of the lens in the eye to focus on what we look at. You can choose to mis-focus and things go blurry.  Anyone can do it.

Magic Eye pictures rely on voluntarily blurring vision.

Magic Eye is not related to blurring vision. it is about changing perspective and look at an image in a different depth. Search for Stereogram.

No, blurring just means you've moved the focal point of your eyes wrt to some object or plane. With Magic Eye you put your focal point passed the plane of the  image.

If the focal point wasn't in the plane of the book, the image would be blurred.

Magic eye pictures rely on shifts of convergence, rather than shifts of focus.
