1. An ophthalmic apparatus being aligned to an eye to be examined, the apparatus comprising:
means for examining the eye of an examinee, a first infrared or near infrared light source adapted to emit light beams in a first direction, a second infrared or near infrared light source adapted to emit light beams in a second direction, the first direction being different from the second direction, the light sources being adapted to be switched on and off alternately, a detector sensitive to infrared or near-infrared light with the capability of detecting the light reflected from the examinee's face as a consequence of said emitting, and of detecting the direction from which the light is reflected from the examinee's face, means for judging based on the detected direction, based on a difference in intensity of the light in the directions of the first light beam and the second light beam, whether the apparatus is aligned against the examinee's right or left eve for the examination, and for registering the examination result of the eye and the eye that was examined, and said infrared or near infrared light sources being associated with different eyes and directed to emit light in different directions in such a way that one of the said light sources is directed for emitting a light beam in the direction of the examinee's face, and the other of said light sources is directed for emitting a light beam so that at least a majority of the light beam misses the examinee's face. |
