  CRT’s have a refresh rate which basically means they never display the full image on the screen at one time. It constantly flickers one half of the screen and then the other half of the screen extremely fast. A refresh rate of 60 times a second is common. The higher the refresh rate, the easier it is on the eyes.

  LCD’s dont have a refresh rate, so the eyes aren’t looking at a flickering image, just one static image.

  it has a lower radiation rate

  Combination of the 2 answers. The first answer is completely correct. The 2nd answer is based on the fact that the CRT works by emitting Cathode Rays at the screen, which is made up as phosphor. This phosphor slows down the cathode rays and turns them into visible light rays. But over the years as the phosphor depletes, cathode rays leak through, and get to your retinas. The LCD avoids radiation altogether by using a standard fluorescent tube to filter light through a series of electro-reactive crystals.

  As well as that, getting a Widescreen is much easier on the eyes - follows the eye's natural inclination to pan left and right, instead up left/right/up/down. Also takes into consideration that with 2 eyes we dont have a "square" or uniform field of vision, but a rectangluar/oblique field of vision.
