Focusing Screen Question

[Synergy]

What are the effects of putting your focusing screen in back to front? I’m concerned I my of put mine in back to front and it’s affecting the focusing. I’m going to check by shooting a roll of film but thought I’d ask some experts first!

Cheers

If there isn't a tab that lets it only go in one way I wouldn't worry about it.

My RTS II screens will only go in one way, but looking at them makes me think they'd work either way if they'd go in.
