Eyes open or closed?

Eyes opened (reading) for a while before going into sleep mode...

When your system throws great images, no point is not watching them dance in front of you. That is the actual fun!

Usually, eyes opened in a lighted, or sometimes, a dimmed, but not dark room. 

For me, the image and soundstage on my system, is so well defined, closing my eyes does not help enhance the illusion at all.
