Lens Haze.
It was noticed that lenses gained a hazy surface, no doubt due to atmospheric reactions with the glass, pollutants, etc. It was also noticed that lenses that gained this hazy coating had reduced flare.
It was then a small but difficult step to inventing coating procedures.

More importantly, can it be removed and if so, by what means?....a forum search suggests that this question is rarely asked and not really answered.
I have tried elbow grease, isopropyl alcohol, spit and vigorous rubbing - with only limited success..
Oddly, the presence of the haze does not seem to have that detrimental an effect on image quality?
