Optometrics revisited

Doctor, I have a problem, my left eye sees 5 Megapixels, while my right eye only sees VGA!?

From time to time one realises that the points of reference that we have held to be certain for some time are in need of an update (much like how we use and interpret scripture - e.g., very few Christians would accept that the ownership of slaves is acceptable, even though the notion is supported in certain texts in the New and Old Testaments).

The cartoon above illustrated just how this shift needs to take place from time to time - it is an update to optometric science!
