- A dilated eye exam allows your ophthalmologist, or optometrist to see the retina, macula, optic nerve, and other structures inside your eye more clearly.
- The effects of dilation generally last about 4 to 6 hours and may temporarily cause light sensitivity and difficulty with close-up vision.
- Whether you can drive after eye dilation depends on how your vision responds, so bringing sunglasses or arranging for a driver may be helpful.
If your ophthalmologist recommends dilation during your next appointment, knowing what to expect can make the experience easier. What is a dilated eye exam, and what is eye dilation designed to accomplish? Dilation temporarily widens your pupils so your ophthalmologist can obtain a clearer view of important structures inside your eyes and look for signs of eye disease.
What Is a Dilated Eye Exam?
A dilated eye exam begins with special eye drops placed into each eye. These drops temporarily widen the pupils, creating a larger opening through which your ophthalmologist can examine the inside of the eye.
Dilation provides a more complete view of areas including the retina, macula, and optic nerve. Examining these structures can help identify changes that might otherwise be difficult to see through an undilated pupil.
What Happens After the Dilating Drops Are Applied?
After the drops are placed in your eyes, you will typically need to wait for your pupils to widen before the examination continues.
Temporary dilation effects can include increased sensitivity to bright light and difficulty focusing on objects up close. Reading a phone, computer screen, or printed material may be more difficult until the drops wear off.
For most patients, these effects generally last about 4 to 6 hours. Individual experiences can vary.
Can You Drive After Eye Dilation?
A common question is, can you drive after eye dilation? There is not one answer that applies to every patient because people respond differently to dilating drops.
Some people remain comfortable with their distance vision, while others experience enough glare, light sensitivity, or visual difficulty that driving after eye dilation may not feel safe or comfortable.
Consider bringing sunglasses to reduce sensitivity to sunlight after your appointment. If you are concerned about your ability to drive safely, arrange for someone to take you home.
Can Dilation Be Reversed More Quickly?
Some patients may also have the option to use dilation reversal drops after their examination. RYZUMVI is one option intended to help reverse pupil dilation after an eye examination.
Whether a dilation reversal drop is appropriate will depend on your individual circumstances. Your ophthalmologist can discuss whether this option should be considered during your visit.
Preparing for Your Dilated Eye Exam
A little preparation can make your appointment more comfortable. Bring sunglasses for the trip home and plan for several hours of temporary light sensitivity or difficulty with close-up tasks. If you are unsure how dilation may affect your ability to drive, arranging transportation in advance can provide added peace of mind.
