Introduction: Screen Not Emitting Light

We are staring at luminous bodies (displays) all day long. Eye strain, sleep disorder, decline in concentration. They are all side effects of “Light”.

E-Ink (Electronic Paper) does not shine. Read text with reflected light. That is experience of “Paper” itself that mankind has continued for thousands of years.

1. The Color Note: Kobo Libra Colour

While Amazon Kindle finally lags behind in colorization, Rakuten Kobo made first move. Equipped with Kaleido 3 panel, realizes gentle coloring of pastel colors.

4. The Digital Detox

Please do not bring smartphone into bedroom. Place Boox Palma instead. Without being disturbed by notification, without brain being burned by blue light, read book quietly and fall asleep.

That is ritual to regain “Rich Night” that modern people have lost.

Conclusion: Sanctuary of Thinking

Device that can do anything (iPad) is convenient, but there are many temptations. Holding device specialized in “Reading” and “Thinking”. That is creating Sanctuary where no one disturbs in your brain.
