Is it really true that eReaders are easier on the eyes than comparable displays? (It seems true to me, anecdotally, but I'm curious if this is just a marketing campaign playing tricks on me).
The PPI of eReaders don't seem that much higher than comparable high quality phones/tablets. Is there a theoretical explanation for why eReaders could be better for eye health?
- arsome 5y agoThe main difference is they use e-paper displays which reflect light rather than emit it. Less eye strain due to less difference in amplitude to ambient light.
- 0des 5y agoAt least in the case of the new ereader amazon just released, some of them include LED backlighting.
- frakkingcylons 5y agoLED backlights have been available in ereaders from Amazon, Kobo, and others for a while now. The first kindle paperwhite with LED backlights came out in 2012.
- georgewsinger 5y agoSo in some sense do eReaders with backlights defeat the whole purpose (i.e. increase eye strain back to normal display levels)?
- dgarrett 5y agoThere are no e-ink devices with backlights. It doesn’t make sense for the technology, which is purely reflective. There are plenty of e-ink devices (like Kindles) that have frontlights. Even better are the ones that adjust frontlights based on ambient room lighting. Ambient light adjustment (and lighting warmth adjustment) is what the new Kindle Paperwhite has.
