The optical apparatus includes a light detecting device for receiving light reflected by an eye, and detecting the intensity distribution of the received light, a storage device for storing personal data associated with a personal difference of the eye in correspondence with the different postures and a visual axis detecting device for detecting a visual axis. The visual axis detecting device detects the position of the visual axis using the personal data stored in the storage device corresponding to the posture of the optical apparatus, and the intensity distribution detected by the light detecting device.
