I just thought of a "light exception" which would be to set your house up with a master switch and very bright lights. From your bedroom you could throw one switch and pump 200 lumens into each corner of the house, while your eyes are firmly shut and covered! Then you flip them off and move, trusting that the bad guy will be night blind for several minutes.
Just an idea...
Stunning the bad guy with a suddenly bright light might very well work and be an exellent tactic. If one's bedroom is not included in the bright light pattern then no need to close one's eyes. The question is would most people wire their houses this way?
