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.

With NoBlue Reader You can set the background color of the book you read, so it will be a more comfortable experience, with less effect on your sleeping cycle.

This version of Noblue Reader handles non encrypted PDF files.
