<P>PROBLEM TO BE SOLVED: To provide an optometry device allowing an examiner to easily and precisely confirm the position of an examining eye. <P>SOLUTION: The optometry device is of a self-conscious type equipped with a cornea position collimation optical system for confirming the distance between a lens mounting reference position and the vertex of cornea. The cornea position collimation optical system has a collimation plate with a scale for determining the distance between vertexes, reticles, and first and second indices. The first and second indices are disposed with different observation distances in order to adjust the examiner's eyes to a prescribed distance to the reticles, and are observed with prescribed positional relation when the examiner's eyes are located in the prescribed distance. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
