In brief: Depends on the med

Several different medications can be used to dilate the eye for peripheral retinal examinations.
They have different durations of action from 2 hours to 2 weeks. The most commonly used drug, mydriacyl, (tropicamide) is 1/2 gone in 2 hours, and 3/4 gone in 4 hours on average. Some people are especially sensitive to the meds, especially if you have light blue eyes, and can remain dilated for 36 - 72 hours.

In brief: About 4 to 6 hours

After a routine dilated eye examination, the eyes typically stay dilated for 4-6 hours.
There are several different dilating drops that can be used, but the usual drop - tropicamide (mydriacyl) - lasts on average at least 4 hours. A second drop that is often used (phenylephrine) has a shorter duration (about 1-2 hours) and is used to speed up the dilation process.

In brief: Depends

Length of time for dilation varies with the person and with the agent used to dilate the eyes and the amount of medicaion used.
The doctor may want long term dilation or short term. For general exams, the pupils may dialate for 1-4 hours.
