another thought I had reading this thread through is has anyone tried
Gunnar Glasses for reading on tablets or monitors I've thought about ordering a pair a few times myself for their blue light filtering and anti glare properties.
Really they are designed for gamers to reduce eye strain but it's another thing that caught my interest when I was thinking about how to sort my body clock.
I'm curious if they help or not although I do suspect any glasses with the right filters would probably work just as well.
