A Friend of mine that has his Rift a few days now told me today, that he had a massive bluried vision after unsing the Rift more than 2 Hours in a row.
Seems that his eyes took about 20 Minutes to "refocus" in the "Real World". He said he wasnt able to look clear for about 20 Minutes.
Is that True?
Even a German online PC Mag (http://www.golem.de) has written about this "issue".
Thanks, Sharkku. I was hoping to avoid going into a biological explanation of how the eyeball works. I learned all this over the last couple of years when I switched to contacts (which changed the way my eyes focused from when I wore glasses), and all the research I did before I had LASIK. My eyes behave much differently now than they did, I can feel the lens working when I change focus, and I have a lot of difficulty in focusing on objects very close to my eyes (the exact opposite of what it was before the procedure). I keep bringing up reading glasses because they work the same way as the Rift's lenses, they allow you to focus on something close to you (i.e. my Kindle when I'm snuggled up in bed) while the lenses in your eyes are "relaxed" to infinity. The other old folks who wear reading glasses for up-close stuff will know what I'm talking about.. hehe.

This cannot be reiterated enough. Parents who think their kids are somehow immune to these kinds of issues could be putting their children's eyes at risk. It amazes me when I read posts by proud parents who ignore the safety warnings and might be permanently damaging their kids' eyes.
It seems that for some people who spend longer periods in the Rift, this uncoupling of the reflex lingers long after the Rift is taken off. I don't know why this is the case, I myself have never had any problems with this. Rest assured though, it's not dangerous, and similar to what happens when you view stereograms like this: http://www.3dstereograms.com/ Your convergence-accommodation reflex will return after a while.
Yes, indeed i think that will descripe this "issue" very good.

If you put your less than 7 year old in the Rift for a short amount of time and not that often it's not going to cause any permanent damage. It's no more harmful than when that same kid grabs her grandfathers glasses and runs around with them on.
That being said I understand why they have that health disclaimer. And they should. Most parents will not be diligent enough and the kids will end up using the Rift for hours.
