anecdote++ I noticed exactly the same thing with a very similar set of orange glasses. Without them, I tend not to get that drowsy feeling in the night, at least before going to bed. I have to go to bed, and then wait to (hopefully) start becoming sleepy. When donning the glasses in the evening a couple hours before desired bedtime, though, I can be reading a book or watching something on TV at night, and I start feeling sleepy before going to bed, which is a major improvement.
