If you have not already done so, replace your old tube-style monitor with a flat-panel liquid crystal display (LCD), like those on laptop computers. LCD monitors are easier on the eyes and usually have an anti-glare surface. Older monitors can cause a noticeable “flicker” of images, which is a MAJOR cause of eye strain. When choosing a new flat panel display, select a screen with the highest resolution possible. Finally choose a relatively large display. For a desktop computer, select a display that has a diagonal screen size of at least 19 inches.
