If your eyes have ever been left blurry and light-sensitive after an appointment, that's dilation. It's a routine, important part of a thorough eye exam — here's why we do it and what to expect afterwards.
What dilating drops do
The drops widen your pupil — the opening at the front of the eye — so more light gets in and we can see much more of the inside. It's the difference between peering through a keyhole and opening the door.
With your pupils dilated, Dr Leong can examine the retina, macula and optic nerve at the back of the eye in proper detail, and capture clearer scans. Many important conditions are found back there, so it's often the most valuable part of the visit.
What you'll notice
The drops sting for a second or two, then take about 15–30 minutes to work. Once your eyes are dilated, your near vision goes blurry and everything looks brighter and more dazzling — bright sunlight can be uncomfortable.
These effects usually wear off over about four to six hours, though for some people it lasts a little longer. It's completely normal and not harmful.
Plan for a lift home
Because your vision is blurry and light-sensitive afterwards, it's not safe to drive yourself straight after dilation. Arrange for someone to drive you, or plan to take a taxi or public transport — and bring a pair of sunglasses for the way out.
By the next day you'll be back to normal. If you have any lasting concern, just give us a call.
