DJ, what an eye doc can get your eyes to do with medication is one thing. How well they function in low light can be quite different.
The eye only dialates as much as it needs to. Twilight requires it to dialate only to about a 5mm size as a rule.
While it is common that many over 40 eye's can't dilate all the way to a 7mm pupil size, it isn't always true. Mine work as well as always and I'm 62. I just walked an old logging cut in full darkness w/o moon. Couldn't see anything much over 8-10 feet clearly, but that was enough. No lights needed. Under those conditions, my fancy Leica binoculars don't work at all. They produce only a 5mm exit pupil. But, again, before legal shooting hours, they were up and working. E
