摘要： An apparatus for detecting astigmatic axes and measuring refractive powers such as the lens of a human eye. A disc has a first group of slits oriented in one direction and a second group of slits oriented perpendicular thereto. Each slit has a deflecting means with a direction of deflection perpendicular to the lengthwise direction of its slits for measuring the refractive power. The apparatus also has astigmatic axis detecting target means which can be used immediately prior to the refraction so that the refraction on each astigmatic axis can be measured before conditions change in the eye.
