What do dilating drops do and why do I need to have them?

Dilating drops are used to enlarge your pupil so that the Ophthalmologist can get a much wider and better view of your retina (the back of your eye). Since the pupil becomes larger more light enters the eye and as a result patients may experience a sensitivity to light/glare whilst they are working. It also becomes difficult to focus and vision becomes blurred, especially with reading. These effects of the drops can last for several hours and as a result, we recommend that you do not drive after having dilating drops.
