btdtst; I understand from Dr. Drew that you are an ophthalmologist and therefore you know more about this subject than all the rest, including the shooting gurus. So, what do you think of Chris Batha's statement that humans can only maintain this visual "focus" or as you put it, "concentration" for only one-half a second, or thereabouts? If it is a matter of just concentration, I would not think Batha's argument holds water. Also, does inability of the aging eye to accommodate as well as younger eyes have anything to do with this? Thank you for your opinion.
