Am I crazy or just foolish?

First...define "filthy".
Unless you have a very unusual situation, contamination inside the eyepiece is very rare.
If it's so bad you have to take them apart, I'd consider contacting wherever you got them and complaining.

Visibility where I am in Georgia is getting so bad I've been hoping for the formation of another Moon or two so I'll have something to see even when conditions are "good".
Any more I'm thrilled when they do reruns of "Earth Vs. the Flying Saucers" on the Sci-Fi Channel.

Eye Relief for Eyeglass Wearers?

Posted By Lawrence Aldrich

It's the other way around, Darian.
Eye relief of an eyepiece has to be sufficient (around 20mm or so) to ALLOW you to comfortably keep glasses on and still be close enough to still see the whole FOV.
The eye relief of an eyepiece has no effect on whether you NEED to wear glasses while viewing.
I hope I'm not misunderstanding your question.
