nikon - Are there any alternate eyepieces for people with glasses?

Any recommendations for an alternate DK20 eyepiece for a Nikon D3200 or D5100 that gives a better visual for wearers of glasses? Amazon has many but the reviews are all over the place. My glasses keep me from getting my eye close enough to the viewfinder to see the full frame.

Thanks!

I've found that something like this: http://www.amazon.com/Hoodman-Glasses-Hoodeye-Eyepiece-Cameras/dp/B007NKPSFW tends to do the job.

It's really just a simple idea. An enlarged eyepiece to cover the eyeglass lens. I bet it wouldn't be to hard to fashion something yourself. :D
