Why Does Your Eye Doctor Dilate Your Pupils for an Eye Exam?

If you’ve been following the guideline to have regular eye exams, then you’re probably familiar with having your pupils dilated. Why does your eye doctor do this?

By dilating your pupils, the eye doctor can get a better view of your inner eye structures – so the eye exam is more comprehensive and more detailed. While the back of your eye can be seen through an undilated pupil, it cannot be examined as fully.

A full evaluation of your macula, retina and optic nerve is possible through dilated pupils. In many common eye diseases, such as macular degeneration, diabetic retinopathy and glaucoma, these are the parts of the eye that exhibit signs of a problem. Also, health conditions such as high blood pressure, high cholesterol and diabetes can often be detected on these parts of the eye.

What happens when the eye doctor dilates your pupils?

Your eye doctor or a technician will insert eye drops into your eyes; it takes 20 – 30 minutes for them to take full effect. Then, your eye doctor will use a lighted microscope to inspect your eyes.

Initially, you may feel a slight stinging when the drops are first inserted, but the discomfort is typically minor and short-lived. For a few hours afterwards, your eyes will be extra-sensitive to light and vision may be slightly blurred. Wearing sunglasses can help manage this sensitivity. Dilation usually wears off within four to six hours.

Even though getting your pupils dilated for an eye exam may feel like a nuisance, it enables your eye doctor to check your ocular health and overall body health with much more accuracy. So the benefits are clear! Contact an expert eye doctor near you to schedule an eye exam.
