Dilated Eye Exam: What to Expect Before and After the Drops

Quick answer

A dilated eye exam lets the ophthalmologist see more of the retina and optic nerve. The drops can temporarily blur near vision and increase light sensitivity. Duration varies; ask the clinic about driving and plan your day around your response.

Why are pupils dilated?

The pupil is the dark opening in the iris. Widening it lets more light in and provides a broader view inside the eye, which is important for diabetes screening, retinal and nerve checks, or assessment of certain symptoms.

What happens during the exam?

The drops may sting briefly. After they take effect, the ophthalmologist uses a light and lenses or imaging equipment to examine the retina. Mention your medicines and any previous reaction to examination drops.

Is temporary blur expected?

Reading and phone use may be harder for several hours, and bright light may feel uncomfortable. Bring sunglasses if helpful, and avoid driving until your vision feels safe. There is no single duration for everyone.

When should you contact the clinic?

Contact the clinic if the effect does not begin to wear off within the period you were given, or if severe pain, marked redness or nausea with blur occurs. These symptoms are unusual after an exam and need medical guidance.
