I remember as a little kid (back when 10 inch black & white TV screens were the latest technological marvel) that we kids were told to sit at least six feet away from the screen because otherwise A) itd ruin our eyesight and B) the screens gave off gamma rays and, worst of all, C) those dreaded gamma rays would shrivel our brains and instantly frazzle our gonads.

Now, TV screens are massive! Does that mean kids should sit at least thirty feet way from a flat-screen TV? Or more? Or less?

Are today's flat-screen TVs less toxic than those old 10 inch cathode ray tube black & white tellies? If modern TVs are less toxic, what is the recommended safe distance for kids to sit away from a flat-screen TV?

Nowadays it's all about the relationship between screen size, number of pixels and viewing distance. Have a look at:

Most tellies are lit by LEDs, so no worry about radiation or retinal damage from stuff outside the visible spectrum

Thanks Siasl. Thanks for that link...it explains it all. I'll be able to wave it maniacally at any (ie all) kids who want to sit with their noses superglued to my 50 incher.

I really dunno why kids do it! But they all do...I did it, my kids did it, kids of friends and even grandchildren of friends  still do it...four whole generations of kids have done it!

But now I'll be armed with that web-link and wielding my scary spring-steel tape measure and a piece of chalk like the referee from hell - Isn't it just shame that the warning "Sit further back from the big screen kids, or you might be able to see the edges of the pixels!" isn't anywhere near as blood-curdling as "Sit back kids or the fiendish gamma rays will nuke your wobbly bits!"

Now, that old threat used to have a real night-before-Armageddon ring to it. But, Tempus fugit, as they say.
