Guys, I made a stupid mistake. I saw dust on the outside glass of the viewfinder, and I mouth-blew the viewfinder outer glass. (I thought the viewfinder was well sealed.) Then what happened next made me regret.
The inner glass (most probably the diopter glass) fogged up, even when the fog has receded from the outer glass, I can still see water vapour condensation in the inner glass. After the condensation has cleared, dots appeared in the inner glass -_-. Now they won't go off. But if I look through the viewfinder I can't see them, only when I look form the outside using a torch will I be able to see the dots.
I always store my equipment in the drybox. So do I need to worry about the dots (most probably dried-up water marks) and send my camera for a clean-up or just leave the camera in the dry box for a few days? Paranoid or ??? Thanks.
