摘要： Ophthalmometer comprising a chart projecting optical system for projecting a Landolt type inspection chart and a lens means for locating a corrective lens in the projecting light path. A manually operated switch is provided for actuation by a patient. A mark is presented and moved around the projected chart image for the purpose of having the patient actuate the switch when the mark is at a position corresponding to the slit of the chart. When the switch is actuated at a correct time, the chart advanced by one step but when the switch is actuated at an incorrect timing the lens of next larger dioptral valve is placed in the projecting light path.

摘要： Ophthalmic examination chart projector including a rotatable chart carrying disc and a mask plate which are co-axial with each other. A light source and a projecting lens assembly are provided for projecting one of the charts on the disc and one of the mask openings onto a screen. An index tube is rotatably mounted in the projecting optical path and carrying a colored filter on the inner periphery thereof. Thus, an astigmatic index can be projected on the peripheral portion of the astigmatic examination chart. The chart carrying disc, the mask plate and the astigmatic index tube can be controlled by knobs all provided on the front panel of the projector.

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.
