Reading Glasses or 150 Year Old Eye Drops for Presbyopia?

I happened to read an article about the use of pilocarpine for age related difficulties reading up close. As a primary care physician with an interest in ophthalmology and a lifelong amateur photographer, I knew darn well that these ancient eye drops constrict your pupils and therefore give you a better depth of field, just like when you choose a smaller aperture on your camera. The same phenomenon is involved when I have to pull out my reading glasses instead of my progressives, trying to read the menu in a dimly lit restaurant that forces my pupils to dilate to pretty much see anything. It never occurred to me that this ancient drug could actually be used in lieu of reading glasses.

Old drug with new application, and obviously this particular formulation is patented by Abbvie.
