[citation][nom]billcat479[/nom]It seems people don't follow the news on this area very much. It's not sounding all that great. I guess most people haven't read that people using 3D tv's have been getting headaches and it's not a few but a lot of people. They should have left it in the theaters. I wouldn't be surprised to find if and when they do a good long term study of people using them long term in gaming start to have long term medical problems if or when they get around to doing good studies on the topic. I have read enough to stay away from this 3D glasses hardware. At best I'd only use it very little and for short term use. They really do need to do medical testing on this because people are being effected by prolonged use of 3D glasses with tv. Add all day video gaming and I think there is a possibility small or large of long term or perm. damage to people. They dumped this on the market pretty fast without doing any studies that I know of but with the amount of people showing headaches I think it is getting more attention or should damm well start checking out the possibility of any chance of eye damage or worse. Eyesight is pretty useful. If they ever get a holographic display then I'd be into it.[/citation]
This is the kind of uninformed, ignorant posts that irritate me. Interweb wanna be docs who don't know how the human body works. Allow me to educate you.
People used to say that "reading a book in the dark" or watching TV or normal PC monitor "too close" would "damage your eyes". In fact we know today that eye sight degeneration has a few factors, none of which are from normal straining.
The most common cause of eye sight degeneration is Presbyopia (from the normal aging process, where the lens progressively loses its capacity to increase its power for near vision)
Also, UV rays degenerate tissue so it's recommended you way UV protective sunglasses when outside in daylight. UV rays can cause your eyesight to weaken over time.
Also refractive error(Common in people ALL ages): A condition may be either because the eye is too short or long in length, or because the cornea or lens does not have the required refractive power. There are three types of refractive errors which are Myopia (near-sight), Hypermetropia (long-sight) and Astigmatism which is the condition where the eye does not focus the light evenly, usually due to the cornea of the eye being more curved in one direction than the other. It may occur on its own or may be associated with myopia or hypermetropia.
The very worst thing that 3D vision can do in terms of negitive health effects, is the same EXACT effects of reading too much, IE; an extremely short term headache. To cure the headache TAKE A BREAK.
Also, as you build tolerance to 3D vision (As I have just after a week or 2 of consistent use) the headaches go away. Also Nvidia 3D settings allow you to adjust the depth of the 3D, less depth = less strain and you can progressively increase 3D as you build tolerance to the use of 3D monitors.
In closing, don't post nonsense about what you don't understand. It makes you look stupid.
