I have expended all of forty seconds on considering this weighty question.
I imagine that if I rigged goggles as a tachistoscope,  I could with the 
greatest ease
 display the difference between a fuzzy image and a sharp image - both 
briefly presented
to an infant.

Is it just possible that opthalmologists, optometrists etc.,  are on 
average about as
 smart as the average physics teacher?    :-)
