摘要:
An opthalmological instrument including a blinking detecting device for positively detecting when an eye is blinking to thereby eliminate errors in optical measurements due to variations in the signal light produced by the blinking. An optical system receives light beams reflected from a portion of an eye under examination to form an image of the front portion of the eye in an image plane. An image pickup element is disposed at the image plane and produces an output video signal in response thereto. A detecting circuit which receives the video signal determines whether or not the image pickup element exceeds a predetermined threshold value. If the threshold value is not exceeded, an indication is produced that blinking has occurred.

A device for measuring the refractive error of an eye in which refractive powers in a plurality of longitudinal directions are simultaneously measured with a high S-N ratio with a high accuracy. A movable chart is provided in a predetermined direction in a plane perpendicular to an optical axis of an optical system which projects the image of the chart onto the retina of the eye being examined. Measuring means measures the refractive error of the eye in accordance with the state of the optical system at the position thereof at which the image projected onto the retina is in focus. The chart has plural striped patterns which are oriented at different angles from one another.
