Back in October 2020, I measured the progress of eye pupil post-dilation restoration following an eye exam and described the experience at this URL:

Using the same technique after another eye exam here in September 2021, I repeated the measurements. The two sets of results are as follows:
I then tried to compare these two sets of measurements to each other by plotting them in Excel with the following results:
Trying to compare these two charts was a problem. Both the vertical and horizontal axis scales are different because Excel automatically assigns that scaling depending on the numerical ranges of the subject data. Those were different both in the number of elapsed hours and the numerical ranges of the ratios.
Since I don't know of any way to force Excel to scale its charts to my wishes, I had to achieve the desired scaling in a different way and yes, it was a bit laborious.
I added some false data (green above) to each end of the valid data so that the two sets of data shared the same maximum values of the vertical axis ratio values and the same maximum values of the horizontal axis elapsed hours values. Then I ran Excel plots on these altered sets:
Note the identical vertical and horizontal scalings. The next step was to remove the green areas of these two graphs to make them representative of only the valid data:
With these two graphs now sharing the same vertical and horizontal scaling, I overlaid one chart on top of the other:
Now I had my comparison and yeah, I guess they roughly do approximate each other.
The basic conclusion is still the same as it was though. My eye recovery from ophthalmic dilation takes on the order of eight hours which suggests a similar fact would be true for you as well.
I would suggest that you don't drive or do anything else critical until that much time has passed following an eye examination.
