can you focus unfocus your eye lens at will?
then youre more evolved that other men when this book was wrote

Ciliary muscles – These muscles adjust the lens to sharpen the object we want to see. At rest, these muscles are set for distant vision. We do not have conscious control of these muscles.
i noticed this changes in me:
often see auras and youtube stereovision, also percieve stereovision with colours and lack the lower wise teeth
anyone else expereimenting anything odd pointing to a superfast evolution?
If there is an object close to my eyes, I can switch focus between the object and the background, but if there is no object I can't bring the background out of focus. So it's obviously not freely adjustable, focusing always needs an object to focus on. I can't unfocus my eyes, only refocus, and this is exactly what it says in the link.![]()

the point of the article is that the scientific comunity is not up to date in this subject
actually the wiki, though controversally and without agreement is more up to date on this:
http://en.wikipedia.org/wiki/Accommodation_(eye))
Accommodation acts like a reflex, but can also be consciously controlled.
Actually some people can focus on a point in space where there is no object. That ability is a huge advantage in a fighter pilot. Of course, you do not know exactly at what distance you are focused but, if you constantly scan and change your focus, you will be able to pick out distant aircraft before those without the ability will.Originally posted by dirkpit7:

I can do it. At least I can "defocus" an object I'm looking at without focusing on another. I've only had one opportunity to try it out and I was so excited that I was actually in the tailgun position of a flying B-17 that I completely forgot to do any testing. I'm a spazz.

I can focus and unfocus my eyes at will. I can also wiggle my ears, flare both nostrils at the same time, as well as alternate between the two, and also do the 'Spock maneuver' with either eyebrow. I know it sounds weird, but I couldn't do these things at first when I was a little kid, so I started practicing how to do it. The reason I learned was because some of my schoolmates could do these tricks, and there was no way in hell I was going to let myself get left behind by these guys.(I learned how to do the Spock eyebrow thing by holding one eyebrow down and concentrate on moving the other one, and was eventually able to do it without having to hold them down. Even as an adult I'll still use the 'SpockBrow' and won't even know I did until folks'll comment on it. I had to use the same procedure learning how to wiggle the ears and the flare the nostrils.) Also, the focusing/unfocusing ability needs to be honed with at least occasional practice by going back and forth between hard and soft focus.
FWIW, I think that barring a physical problem that could prevent them from doing so, everybody has the ability to do these kinds of things, it's just that they never took time teaching the muscles of they body how to do it.![]()
I wonder if the unfocusing ability is actually just a relaxation of the eye muscles, when the focus becomes set for distant vision (as the link says). Then an object close to the eyes appears blurred. I can do that too, but definitely not what Outlaw described, i.e. voluntarily fix my eyes to an empty point in space.
As far as I remember the muscles that move the ears are diminished evolutionaty remnants that can be activated with training, just as Messaschnitzel said.
