Zusammenfassung:	PURPOSE:To provide a contact lens which enables the miniaturization of the whole device to be used for the virtual reality and facilitates ordinary observation and the observation of a display screen. CONSTITUTION:This contact lens 1 is used as an optical element of a device to be used in the virtual reality. A display screen observation region 2 having the refracting power to enable the observation of the display screen existing near the vertex of the cornea and an ordinary observation region 3 having the refracting power different from the refracting power of the display screen observation region to enable the ordinary observation are formed as one piece of the contact lens.
