My motivation for getting my Clara HD was that I really wanted to reduce the blue light glare when reading at night compared to my PW1. For a while, though, I was considering buying some orange gel filters online and cutting them to fit in the screen recess as an overlay to use at night. I’ve not tried it, so no guarantees that it’s a good idea, but that might work for you.
Not a suggestion, just first item that I found to link to as an example:
