Computer screens/radiation/eyesight protection

Some of you computer/tech savvy people out there might know this,
hopefully. Are computer screens still using fluorescent lights nowadays? If not, is
what they are using, bad for our eyesight? Is there something they make
that can protect our eyesight while being on the computers? Same question for
larger screened tvs too.

Thanks in advance,
Amy

Probably over 95% of the LCD computer monitors still use fluorescent
lights as a backlight. Very few newer ones use LED lights. I'd
say that all computer monitors are bad for eyesight, simply because
of the distance you have to focus (although reading a book would
be worse). Reading or computer glasses might help with that,
although that may not be the issue you are concerned about?
(and any metal in those glasses may make your ES worse!)

Thank you Marc. Do you think they actually make screens or protectors you
can put over your screen that would protect your eyes? I wouldn't even know
what you would call them. That would be a start I guess.

Thanks,
Amy

They do make screen protectors which limit the field of view, and also
ones that will drain off the electric field... I'm not sure if either of these
are going to protect your eyes much, however...

How about adjusting the monitor settings? When I try, the separate red,
green and blue come up. In order to protect our eyes, would adjusting these
help? I'm thinking more red and less blue? What about green?

I just read something a few days ago about fluorescents, and how they have
too much of one color spectrum which is what damages our eyes, but darned
if I can find that thing now! Even searching the internet was no help for
me. Mostly photography issues came up. Any help is appreciated!

PUK REPLIES - The obvious things like making sure that there is no glare
reflection on your screen, not facing a window looking at bright daylight,
taking a rest BEFORE your eyes get tired, reducing other visually demanding
tasks so that you dont go from one to the other, good general lighting, good
humidity in the room, eye supplements. Remembering to blink as your blink
rate goes down when staring at a screen, play around with the refresh rate
of the screen if possible to see which setting feels more relaxing to you,
this is sespecially true if you have flourescent lights in the background
as you may get a stroboscopic effect from the screen and lights competeing
at similar frequencies 60-100hz and so on...... The bottom line is that you
should try not to spend to long staring at a screen wether its CRT LCD if
you have to keep refocusing the eyes on diferent distances .
