Haze in the viewfinder window

[uniart]

Hi everyone,

I am going to bid oh M7II kit at ebay. In description of this camera is mentioned some "haze" in the viewfinder window. This is the quote:

"The only minor defect is a haze in the viewfinder window. This does not negatively affect the light meter, focusing, or composition. I must point this out in text because it cannot be seen in the pictures."

Did anyone hear about this defect ? Is it important? Could it result in future the problems with the camera?

Any income welcome,
