Yes, it’s amazing, isn’t it, how much information you can get through a simple Google search, especially on an optical principle that’s so well documented. In addition to that nasty, commercially tainted source I cited, you also find scads of scholarly articles and print references, all curiously saying the same thing as my unworthy source.
The consensus seems to be that large pupil diameter produces optical aberrations in the eye that reduce visual acuity. Extremely small diameters (on the order of <1.5mm) lose some acuity due to diffraction (not due to insufficient light reaching the retina) in non-myopic eyes, though they can improve acuity in myopic eyes.
If you can find information to support your assertion that dilating the pupils improves the optical performance of the eye by allowing it to “see more”, I’d like to see that.
