I don't really see much of anything on those pictures either. I can't even tell that there is a kindle on the right.
I can read 6 in a totally dark room, although I never read like that. But anything below I wouldn't be able to make out words anymore. On a Voyage or Oasis.
Normal mode Oasis at 1 or 2 light would only be readable in daytime light for me. Never in any dark situation.
But then I am night blind and light sensitive at the same time.
. Its also why I could never read on a lighted kindle in a pitch dark room. There must be some sort of side light somewhere, even if its a candle, or a small side lamp. Then reading at 8 with Voyage and Oasis is comfortable.
Interesting as always to see how different all of our eyes are. I love that I can now not only adjust the light and font size, but also the boldness. I found it now as important as the light level. If I turn up the boldness at night a notch, I can have much better contrast at the same light level so I still don't burn my eyeballs out in the dark.
