We have a wonderful skylight in our camper. I love it, except in the morning when it's like a prison searchlight hitting my eyes! It came with a 'light diffusing' shade installed, which basically means it does NOTHING to block the light.
I looked into buying a shade for it - very expensive! So, I've been stuffing a piece of reflectix in it at night. It looks tacky, I may live in a travel trailer, but I have my standards! It also ends up laying around and getting in the way all day, until of course, I need to put it back up and then it can't be found.
