During The Test

Rest your lower back on the back rest of the chair and lean your head slightly forward. You should look straight ahead without tilting or turning your head.

Your eye lashes should be nearly touching the focusing lens in front of your eyes. If the lens holder is blocking your view, please inform the technician.
