ABSTRACT:
The present invention relates to an eye examining apparatus used in ophthalmic clinics. In an eye refractometer provided with a light beam separating member for separating an eye fundus illuminating light beam and an imaging light beam through an objective lens in a position conjugate with the pupil of an eye to be examined, an eye refraction measuring light beam is projected to the fundus of the eye to be examined through an optical passage dividing member arranged between the aforesaid objective lens and the aforesaid light beam separating member in order to obtain the refractive value of the eye to be examined by receiving the aforesaid measuring light beam including at least three meridians using a photoelectric sensor.
