Do you use low radiation monitor?

cafe not only have old monitor but also there is very little space between the computer and ourselves. I work for long hours on computer but i don't feel any sore because i practice the 20-20-20 principle.
that is for every 20 minutes look away from your compute blink 20 times and then look at a object which is at least 20 feet from you.

NO, i am using a tft monitor,I have heard that tft monitor emits very less radiation when compared to traditional crt monitors.For crt monitor,there is a screen available which will block the harmful rays emitted by crt monitors.I have used it when i usd my crt monitor.But i think everyone should move to lcd monitor.It consumes less energy than crt,plus it has a longer lifespan than crt monitors.
