When dilating your eyes, your doctor will put a small amount of eye drop solution into each of your eyes, says the American Academy of Ophthalmology. Within 30 minutes, your pupils should fully open.
Your vision will be blurry, and focusing on close objects will be difficult. And you will be extra sensitive to bright light.
The effects of dilating eye drops last up to several hours, so the academy recommends having someone drive you home after your appointment.
