The secured path to reading is READING YOUR BOOKS instead of reading through the glass or through the internet. BOOKs doesn't need a switch. The switch is just automatically through your mind power to absorb the knowledge. You wont be able to concentrate reading your favorite text books or novels through the net with too many pop ads here and there and the many ads from left to right. Printed books that were published and then paid by you as a cusomer is the safest route. Or whatever really suited your best interest in matters of comprehension. At least in reading the text books or paperbacks you don't get burn. Have you seen people with too many moles and skin tags courtesy of your computer monitor screen?  It's like looking at the powerful beam of sun and you get sunburn. Right, you have to wear sunglasses and apply coppertone now too just in case.

Oh well, how many times I have to warn myself about the ill effects of the radiation emitting out from the computer still is > computer, lap top and notebooks are so powerful to have ruled over us  the earthlings. I wonder what the martians are doing to combat this kind of weird stuff.

Weird or what? The answer is BIZARRE!

Staples should have those filter screen for computer,  available for would be buyers. For you know what? Pair of eyeglasses is very expensive. No one could afford it here in my town. Tsk! Tsk!
