Reece, as you know, I only wear my glasses when I am awake.
I've started slipping a piece of paper under the earpiece. It has to be relatively stiff, ie notebook paper, not tissue. It acts like a snowshoe, and keeps the earpiece from digging into the thin muscles in front of my ears. This eliminates the focused pressure point that causes the pain.
I'm sure it looks dumb, but I'm the only one here, and I can't see it. And it's way more comfortable.
