Can constantly staring at a computer or TV screen have any negative affects on y!
Question: There are 2 ways to look at this question. One is as so: Let's say that you take up a job loading heavy boxes onto a truck...if you're not used to doing that, then at the end of the first few days, the muscles that are involved in getting this done, will be achy and will need to (and will) get stronger. i.e they will acclimate to what you are asking them to do.
Some scientists have taken this approach to seeing if myopia or near sightedness is that kind of acclimation to what you ask them to do. i.e. if you constantly look at things at near, then your eyes will start to build up myopia in order for you to see more clearly at near with less effort - analogous to building the muscles so that you can lift those heavy boxes with less effort. The flip side to that is that the distance then becomes blurry by inducing myopia.
The results over and over again by hundreds of studies is that this is not the case with the eyes and myopia. Looked like a good theory and looked good on paper, but there just isn't any proof that the eyes induce myopia as a response to prolonged near work. Although in my humble experience, I think this IS the case for a small percentage of people. Not most.
The other thing you may mean might be re-phrased into " is there some output from computer display screens or TVs that is physically harmful to the eyes (like radiation)?". If that's what you mean. the answer is most definitely NO.

well obviously, i think.
but that so sure how it works.
yeah. you can get eye strain which can lead to the need for glasses.
I think so. I've noticed mine aren't as good as they used to be.
depends on what your looking at. if your looking at porn, hell ya its going to make you brain dead. car pictures, never.
yyyyyyyyyyyeeeeeeeeeeessssssssssssssss
Yea. Your eyes will get tired and vision may start to go a little blurry or you may get a headache. But its not gonna make your vision bad for glasses or anything.
yeah
it strains your eyes and can give you head aches because of the glare on the computer screen.
youre supposed to have regular breaks when using computers
i think its about 5 or 10 minutes every hour?
God, I hope not!!! :)
