Abstract
An image display apparatus is described for reducing the possibility of the occurrence of minor discomforts such as headaches, eyestrain, fatigue and the like in users. A symbol indicating distance such as 1m, 3m, or .infin. is displayed on an outer periphery of a virtual image adjusting knob. When the user aligns a mark on the virtual image position adjusting knob with a position corresponding to one of the predetermined symbols, the virtual image is set so as to be displayed at a position corresponding to the symbol. Consequently, the user can more easily recognize the displayed position of the virtual image so that the generation of a minor discomfort due to long term use which is more than necessary of the image display apparatus is substantially reduced.
