Abstract: PURPOSE:To enable highly accurate measurement of eye refractivity by eliminating the influence of external light by obtaining the data free from the influence of external light by comparing and computing the images projected on a photo- reception device when measuring light is projected and not projected. CONSTITUTION:The projected image projected on the photo-reception device or the corresponding data when measuring light is not projected on a subject's eye and the projected image on the photo-reception device or the corresponding data when the measuring light is projected on the subject's eye and stored in the second frame memory 16 and the first frame memory 15 respectively.
