The effect of drops used in pupil dilation lasts between 2 and 48 hours, depending on the individual (e.g., it lasts longer in patients who have a lighter iris color and generally in children – in whom dilation drops are administered multiple times for the correct determination of diopters).
Side Effects of the Drops:
- slight stinging sensation in the eye at the time of administration - a sensation that disappears within a few seconds of administration;
- 'foggy' vision especially for near vision;
- increased sensitivity to light (which is why it is desirable for the patient to have a pair of protective sunglasses after visiting the ophthalmologist);
- 'red eye';
- dry mouth;
- 'flush' (redness) of the face;
- temperature;
- rapid pulse.
It is important to note that all these effects are transient and resolve within a few hours, once the substance is eliminated from the body and pupil size normalizes.
