Out of curiosity, I looked it up just to see if it is theoretically possible to augment dark adaption with artificially dilated pupils. I'm not suggesting anyone actually *do this, of course, but I thought it was an interesting thought experiment.
The typical drugs used are phenylephrine and tropicamide (usually together). In
this study, most of the dilations achieved were in the normal range with the exception of 0.5% tropicamide solution where the maximum dilation achieved was a whopping 8mm (but perhaps this individual had an 8mm natural dark adapted dilation as well! We'll never know.)
So I guess it's unlikely that we'll see 'Livestrong' branded telescopes anytime soon :-)
