    • PURPOSE: An eyeball refractive power measuring apparatus is provided to improve the precision of screening by inspecting. CONSTITUTION: A measurement optical system(10) has a light transmitting optical system(10a) and a light-receiving optical system(10b). A glare test optical system(80) has a glare light source. The glare test optical system radiates glare light to examinee's eyes. A guide unit receives the reflection light of the eye-ground through a receiving element. The guide unit determines whether an eye transmission object of the examinee is cloudy or not based on a receiving signal of the receiving element. An input means inputs a mode conversion signal for executing a glare test.
