NoBlue Reader

Reading at night can be very tiring for the eyes, and can put you in a sleepless state. The screens we use are very rich in blue colors. Many researches have shown that this blue-rich light, if seen in the evening suppresses our sleep-inducing hormone – melatonin – production.

I thought this app would work on all media displayed on the iPad, including websites. As far as I can tell, it only functions with things like ibooks which can be converted to PDF format. It is useless for normal surfing/browsing.
