Because in this context "closing" and "opening" would be a continuing action and I don't think that is what is intended or usual.

Please try to give your threads more useful titles. 'eyes open or opening?' would have been appropriate for this thread.

Thank you all!
But I am wondering why adj is after noun in this case.
