Are there any ereaders besides the Aura One that have a blue-light filter?

I've noticed a big improvement in my sleeping patterns when I'm not constantly exposing myself to white LED light. I like the looks of the Aura One but it's a bit out of my price range. Are there any chinese or other ereaders that have the blue-light filter?

The jury is still out on whether blue light on e-ink devices causes sleep problems. It's a very different thing than a tablet with it's backlight shining into your eyes. E-ink readers have a front light shining down onto the screen and we only get reflected light, and a lot less of it.

Alternatively you can try an ereader without a light such as the basic Kindle or the Basic Kobo. These are pretty inexpensive and they're not bad devices from what I've heard and you can be sure there's no blue light since there's no light. You can read by lamplight.

And for the sake of accuracy, the KA1 doesn't have a blue light filter, it just has additional non-white LED's that allow you to choose how much white LED vs other colour (i.e. red) LED gets used (similar effect to what some tablets use to reduce the blue light output).
