What Is Eye Dilation & When Do You Need It
The pupils of your eyes normally get smaller when exposed to light. Eye dilation is when your eye doctor uses special eye drops to dilate, or widen, your pupils. The drops force your pupils to stay open even when the eye doctor shines light in your eyes. This allows the eye doctor to more clearly see the back of your eye, including the retina, the macula, and the optic nerve.
