In the preliminary examination, a drop called cyclopentolate is used. This drop causes the pupil to enlarge and the focusing muscle temporarily no longer works properly. How long you suffer from the drop varies from person to person, but an effect of 24 hours is likely. As a result, you suffer from a lot of light and can see less close.
Geen probleem. Je kunt ten alle tijden de test opnieuw doen om een nieuwe calculatie te starten.
