- Press the blue button once. You will hear one beep. The green light will turn on and the screen will show a series of dashed lines in the bottom right corner.
- Hold the Tono-pen perpendicularly to the corneal surface. Tap gently and try to avoid wild variations in the pressure you apply between taps. For each tap that is recorded, a number will appear in the bottom right corner. You need 10 in total. The larger number is your pressure reading. The smaller number is your confidence interval.
Having trouble getting accurate readings with the Tono-pen? Try calibrating it before using.
