@night-dweller I recommend UVEX skyper SCT Orange eyewear, it's shown in the "filters" list on the fluxometer website that you can access by clicking the top menu button on this page and selecting the link.
Just go to the "just get f.lux" homepage (click the icon at the top of this page!) and select "fluxometer" at the top.
Then select a device similar to the one you use and choose the UVEX filter. You can find the eyewear for less than $9 a piece online.
