No luckily not!
I used to need glasses (I since have had laser eye correction – great invention btw) and I currently suffer from color blindness, tone deafness and virtually no sense of smell.
Color blindness can be a pain – especially when the job requires wiring – I was told as a child I could never be an electrician. Having no sense of smell can be annoying at times too – there have been a couple of occasions where electrical shorts have caused expensive boards to burn out – and these could probably have been stopped if I could smell the burning (I am told the smell is distinctive!).
