AN OPTOMETRIC INSTRUMENT WITH ALIGNMENT MEANS AND METHOD FOR ALIGNING AN OPTOMETRIC INSTRUMENT

摘要

The invention is realized by means of an optometric instrument (1) with alignment means that comprise light sources (10a, 10b) for sending out light beams (3a, 3b) through one or more light channels (9a, 9b) from the instrument (1) onto the retina (4) of the eye (2) of a patient. The light channels (9a, 9b) are directed parallel with the visual axis (11) of the eye (2) at correct alignment, whereat the light beams (3a, 3b) are visible for the patient in an intended way. The invention is also concerned with a method for aligning such an optometric instrument (1). The method comprises the steps of sending out light beams (3a, 3b) from the light sources (10a, 10b) through one or more light channels (9a, 9b) onto the retina (4) of the eye (2) of a patient, and positioning the instrument (1) to have the light channels (9a, 9b) parallel with the visual axis (11) of the eye (2) of the patient as a result of finding a position, wherein the light can be correctly viewed by the patient.
