Now first of all I would like to see a picture of a similar bubble eye at least 20 years old.

Well it's hard to find dates but when looking for pictures to make my case I choose the simplest and that bubble eye above is probably very close to the original. They have gotten real eloborate.

Since it's not clear, based on photo evidence, in which category your "bubble eyes" example belongs, I will leave it out of the list.
