short eye relief

I am wearing glasses.
If I use a binocule with short eye relief, say only 12 or 13 mm, then what can I see?
Less sharp? Less bright? Or smaller area, small images I will see?
Or something else?
Thanks for your answers.

It's also hard to tell for sure whether you're looking through the centre of the image. That means you might not be seeing the sharpest possible image, and it's hard to set the separation of the barrels correctly too.

I've tried it and I don't like it. Avoid it if you can.
