dilating your pupil
wHAT is dilation?
Dilating your pupils entails putting some drops into your eyes, and waiting for your pupils to dilate (See Fig. 1) so that a full retinal examination can be performed. On average this takes 3 instillations of the drops and a wait of around 20 to 30 minutes. The effects of the drops last for around 4 hours and will blur your vision especially for near / reading. It is also important that you inform your doctor if you're driving as this is not advisable after you've had your pupils dilated.
