Eyepiece cooldown?

Hey guys.

Last week I got my first piece of serious glass, my new Meade UWA 14mm.. It's only had 10 minutes of first light last night, every other night has been cloudy/rainy, and even last night there was a big bright thing in the sky which washed out everything I tried to look at.

So can't judge it much at the moment, compared it to my 15mm GSO plossl and with the bright moon the two main things I noticed better in the UWA were the much wider FOV, and sharpness to near the edge.

Just a quick question though, with a seriously large and heavy eyepiece like that (and I imagine like the naglers etc), with so many lenses in it, does it need time to cooldown and reach ambient temperature?
Will it perform better after it's been outside for a little while? Just wondering whether I should open my eyepiece case up to cooldown at the same time I open my scope up to cooldown..

Thanks
