AUTOMATIC EYE RECOGNITION

PRECAUTION!
Do not cover the eye recognition transmitters or sensor during the measurement, for example
with fingers. Keep your hand, hair etc. and objects such as pillows away from the temple side
of your eye, as they produce an infrared reflection that causes an error.
The tonometer includes an automatic eye recognition system that identifies which
eye, right or left, you are measuring. The system has two infrared LED transmitters
just below the probe base and one infrared LED sensor above the probe base, as
in the figure below. The right-hand transmitter sends invisible infrared light to the
right and the left-hand transmitter to the left. The infrared light reflects from your
nose to the sensor. The sensor knows from which transmitter the reflected infrared
light came, and thus which eye you are measuring. The resulting eye indication is
included in the data that you can transfer to a PC, as described in the section 9.
