Are Lcd screens better for the eye?
Along with good health practices when using the computer (taking breaks every 45 mins or so to stare into the distance for at least 2 mins) I would think the only real factor is the SIZE of the screen not whether its OLED,LCD/DLP/Plasma/Projector/or plain ol CRT!
This is because with a bigger screen you can either put the screen further &/or You also will not have to actively focus (contract) your eyes as hard to focus in on a smaller image (as would appear in a smaller screen)
In both cases reducing eye strain & possible associated symptoms like headaches.
The fact is, our eyes were built for looking into a distance which is why with a normal eye, one does not work as hard to focus an image in the distance as compared to an image being focused in the near area.
In general LCDs are sharper than CRTs but not always but I've seen some very nice CRTs and some really bad LCDs.
For a long time I had a dual monitor setup with a CRT on one side and an LCD on the other. I generally used the LCD side for text and the CRT side for images. The LCD was sharper but the CRT had more vivid saturated colors and more contrast.
The flicker,"in general" occurs only when one does not know how to adjust their computer or has a extremely crappy or old monitor/video card combo.
mrevol: Flicker is more noticeable when you're running at a low refresh rate, yes, but all CRT monitors flicker.
In general, yes. LCDs don't suffer from flicker like CRTs do (especially badly configured ones).
