I've heard so many conflicting answers to this question over the years I'd just 
like to know for once, does watching tv/computer monitors in the dark damage 
your eyes?  A friend of mine says it does since the darkened room causes your 
eyes to dialate, letting in MORE harmful screen radiation.  I say that there's 
no real proof tv/monitors are harmful at all and point out that the reflection 
of lights on the screen increase the light bombardment to your eyes anyway.  
Can someone straighten out all this please?
