Poorly sighted person(s)
In much the same way that if I were having a triple heart bypass operation I should rather like to be operated on by a surgeon with first class eyesight and preferably many years of surgical experience when I go as a passenger in a civil aircraft I should like to think that the pilot can see well and is well trained!
Sadly we live in a rather strange world where people just cannot seem to accept that there really are limiations and there have to be standards WITHOUT exception! Sorry my friend if you cannot see - try another profession. I am told Law is a good alternative.
