LCD Causes Less Strain

• Overall, LCD monitors are much better for your eyes than Cathode Ray Tube monitors because LCD screens do not flicker like CRT's; CRT's refresh the screen all at once while LCD's change individual pixel colors. In addition, LCD screens almost always use an anti-reflective coating, which reduces glare, according to All About Vision.
  
  

It Depends on the Environment

• Changing to an LCD monitor cannot eliminate eyestrain by itself. Too much light from your surroundings, such as the Sun, can cause eye strain no matter what type of monitor you use. In addition, setting the screen's bright too high or too low causes eyestrain on all monitors.
  
  

Bottom Line

• LCD screens are better for your eyes than a CRT monitor, but choosing the right monitor is only one part of caring for your eyes, according to All About Vision. Ambient lighting should be about half as bright as your monitor. A screen should not look dull, nor extremely bright. Consider calibrating screen brightness with a white background.
