What is the purpose of dilating the pupils during an eye exam?

Dilating the pupils during an eye exam serves primarily to provide a better view of the internal structures of the eye. When the pupils are dilated, it increases the size of the opening through which light enters the eye, allowing eye care professionals to more effectively examine the retina, optic nerve, and the surrounding tissues. This is critical for identifying potential issues such as retinal tears, glaucoma, macular degeneration, and other conditions that may affect vision.

The dilation process allows for a broader and clearer view of the internal anatomy, which is essential for a comprehensive assessment of eye health. It enhances the ability to detect abnormalities that may not be visible with non-dilated pupils.
