Ah, here we have a plethora of truths listed so nicely. But, to all this must be added the consideration of the natural variation in night vision between those of light eye color and those of dark eye color. This causes conditions that are but dim for one with dark eyes to be pitch black for one with light eyes.
A valid point, especially since the light oscillation involved in an illuminated display acts as a hypnotic stimulant. They do not help with the sleepiness.
The first thing to come to mind after reading this was... why would you read a book in a low light environment? But... yes, trying to read a sheet of paper in the dark is harder than reading a glowing screen in the dark. Some of these studies and manufacturer claims just make my brain hurt.
@Peik Actually, it's unhealthy to read from a screen. Paper and ink is far safer and less tiring.
Kafka's stories are relatively short, so it's not like you're reading an entire novel of madness, but it can feel that way at times! I would suggest checking the Classic section at B&N, I found that book I mentioned at Hastings for $3.99, unless you have a Half Priced Books in your area, not sure if you have either, but discount book stores are my favorite places to look for books (:
