For me, the radiation emitted by these devices was so intense (even at lower brightness settings) that my eyes watered and burned to the point where I was forced to quit. (goodereader.com)
Can you please compare the Oasis inverted mode with Kobo Aura One blue light filter, with lowest brightness settings, under dark lighting conditions (at night)? (goodereader.com)
Be sure to significantly lower the Brightness setting of the display in order to reduce eye strain. (displaymate.com)
