HOW TO ANALYZE THE TEAR FILM STABILITY AND 

REGULARITY 

1 

Place the fine grid or the negative grid on the device lighting 

system as explained in the paragraph How to insert the film in 

the device lighting head at page 33. 

2 

Verify the correct eyes position respectively to the shooting 

channel. 

3 

Ask the patient to look ahead and open and close the eyes for 

a few seconds, so that the tear film is evenly distributed on the 

corneal surface. 

4 

Ask the patient to keep the eyes open as long as possible 

during the exam. 

5 

Check the time between the last patient's blinking and the 

appearance of the film rupture on the reflected tear film 

image.
