This is not only a problem with Swarovsky binoculars. My wife Irma has had
problems with Baush & Lomb and Zeiss rubber eye cups on their expensive
models. She would break out every time we went birding. Ending up with
raccoon eyes.

This must be a more than one would expect problem, because Zeiss sells
ceramic eye cups to replace the rubber ones. Not inexpensive, but the
problem solved for Irma.

Great birding and find that next lifer,

John + Irma = 2, we are birders, too.
