摘要

A line of sight information correction device includes: an input unit that inputs line of sight information obtained based on a condition of an eyeball of a subject who wears an optical instrument that refracts light to enter the eyeball; and a calculation unit that corrects the line of sight information input into the input unit using optical information relating to refraction of the light at the optical instrument.
