ABSTRACT:
The present invention relates to an optical apparatus, which comprises a photoelectric conversion device for converting reflected light from an eye into an electric signal, and a calculating device for calculating a direction of a visual axis of the eye using the electric signal and correction data, wherein the calculating device obtains the correction data using an electric signal obtained from the photoelectric conversion device when the eye keeps directed to a specific portion in the field of view during an ordinary operation of the optical apparatus.
