Okay, the 'pressure' part of the heading was meant as a pun of sorts, so let me
explain my question.

How sensitive are the various Boomer(Buma) optics to pressure differentials?
Would they(the various boomers) take severe damage to their optics if they
entered a situation where the pressure switched from close to 7 atmospheres to
-2 atmospheres and back and forth rapidly?  Would this potential blind them
completely?

That's the questions.  Feedback would be greatly appreciated.
