Take it with a grain of salt what an optometrist has to say, he's not a medical doctor.

What that condition is is called "simulator sickness" in the medical field, it is the opposite of motion sickness with the same result. Motion sickness -- the inner ear detects motion but the eyes indicate that you're still sending conflicting messages to the brain. Simulator sickness -- the inner ear tells your brain that you are not in motion but the eyes say you are, sending conflicting messages to the brain.

The brain reacts to these conflicting messages by using the biological reasoning of where this condition happens in nature -- you've been poisoned, so throw up.

The truth is, this is not an uncommon condition and is nothing new. I have an issue with simulator sickness but not with motion sickness (I have my pilot license and was in the Navy and I don't get motion sick, but certain video games make me nauseous). But you CAN condition yourself to overcome it.

As far as the eye problems, etc, that comes as no surprise either. Wearing dirty glasses/cheap sunglasses/safety glasses/watching TV/extended time on the computer also kills your eyes. Don't think they've got enough data on it to prove that the rate of vision loss from watching 3DTV is any greater than any other thing we subject our eyes to.
