Brightness and Contrast Controls
["I have a ETI2 and there are settings for the backlight and more importantly the contrast that can ease the problem a lot. Often the contrast is overlooked but it can even the background and provide better contrast allowing lower backlight settings and thus longer battery life and less fatigue. Increasing the font size is another way to extend the reading if you get tired. This trick won't turn it into e-Ink but may help when you want to use it"]
The ETI-1 has separate knobs to adjust the brightness and contrast. That is much easier then using the software controls on the ETI-2. I am just not very adept at using them yet.
