--- Comment #33 from paulystefan at web.de ---
This is a big major feature for all users against strained eyes 
and critical for children and young users against short sightedness

german scientist made the break throw.

"However, black text on white paper heavily overstimulated retinal OFF
pathways."

"Therefore, reading white text from a black screen or tablet may be a way to
inhibit myopia, while conventional black text on white background may stimulate
myopia."

Reading and Myopia: Contrast Polarity Matters

Andrea C. Aleman, Min Wang & Frank Schaeffel

In myopia the eye grows too long, generating poorly focused retinal images when
people try to look at a distance. Myopia is tightly linked to the educational
status and is on the rise worldwide. It is still not clear which kind of visual
experience stimulates eye growth in children and students when they study. We
propose a new and perhaps unexpected reason. Work in animal models has shown
that selective activation of ON or OFF pathways has also selective effects on
eye growth. This is likely to be true also in humans. Using custom-developed
software to process video frames of the visual environment in realtime we
quantified relative ON and OFF stimulus strengths. We found that ON and OFF
inputs were largely balanced in natural environments. 
However, black text on white paper heavily overstimulated retinal OFF pathways.
Conversely, white text on black paper overstimulated ON pathways. Using optical
coherence tomography (OCT) in young human subjects, we found that the choroid,
the heavily perfused layer behind the retina in the eye, becomes about 16 μm
thinner in only one hour when subjects read black text on white background but
about 10 μm thicker when they read white text from black background. Studies
both in animal models and in humans have shown that thinner choroids are
associated with myopia development and thicker choroids with myopia inhibition. 
Therefore, reading white text from a black screen or tablet may be a way to
inhibit myopia, while conventional black text on white background may stimulate
myopia.
