The device displays a color and a text indication of the reliability of the IOP reading. If the deviation
between measurements is within normal limits, the color will be green and the text will read
'Deviation: OK'. If the deviation is slightly high, the reliability indication color will be yellow and the
text will read 'Deviation: DEVIATION'. If the deviation is high, the color will be red and the text will
read 'Deviation: REMEASURE'. The table below explains each reliability indication.
