I have needed reading glasses for several years - this is a deficit of ageing.
 When caught without specs, and needing to decode text in small font
I can make do by squinting through closed fingers.
 I know that increased aperture in my eyes is associated with decreased
resolution, in common with the dearest Nikon and the cheapest
Kodak throwaway. But I also know that pinhole cameras are in focus at any
focal length within reason, and so I rationalize that an effect of this kind
 is in play.
