Greetings R-L-X!

I've owned very few vintage watches, so I'm far from an expert in this arena, so I have a question about the dial of my 1680.

The markers of my 1680 are in relatively good shape...not ultra brite white, but not a yellowish patina either, which I don't particularly care for. Is there anything I should do storage wise to keep my dial from further yellowing or at least slowing this process down? I know it's caused by the Tritium on the hands and markers...does sunlight affect this process at all? Other environmental factors?
