Just because your device enables you to read eBooks does NOT mean it is an eReader!Some reactions to my previous post – along with discussion with friends and family – have convinced me that there are a whole lot of people out there who don’t know what an eReader is!
This is understandable because the companies that make devices that enable you to read ebooks on them market them as eReaders. Every year they publish lists of the best eReaders available – and these lists combine BOTH tablets and eReaders.
A Kindle Fire is NOT an eReader. An iPAD is NOT an ereader. Your mobile phone is NOT an eReader. These devices are essentially created to do things other than let you read books. They let you browse the internet, read your email, view your photographs, play games, create spreadsheets, etc. They are tablets that emit blue light and are not conducive to sleep – or your general health. “The use of portable blue light-emitting devices immediately before bedtime has biological effects that may perpetuate sleep deficiency and disrupt circadian rhythms, both of which can have adverse impacts on performance, health, and safety.”
Many devices we own, from the latest iPad to the Samsung Galaxy Note to Amazon’s Kindle Fire, has light-emitting diodes that give off blue wavelength light. And it’s that blue light that wreaks havoc on our body’s melatonin production.
Dedicated eReaders – devices that ONLY allow you to read eBooks (no internet capability, etc.) are the more healthy choice for the avid reader.
The Kindle Paperwhite (my device of choice); The Nook GlowLight; The Kobo Aura; The Kobo Clara are all readers that use eInk. These readers do not display in color – as of yet only black and white.
E-ink readers are not backlit but they are illuminated. These devices were only introduced in 2012. Rather than lighting the screen from behind, illuminated e-ink e-readers are “front-lit” and use small LEDs around the screen, pointing inward rather than outward, to cast a glow over it. This makes easy reading possible in bright sunlight or a dark room without adjusting your brightness settings. (but you can if you want)
As of yet, there is NO scientific evidence that states E-Ink readers are in any way detrimental to your health and well-being. They are no more dangerous than reading a book which is printed on paper.
