I'm trying to decide between buying a Kindle vs. a Kindle Paperwhite. The Kindle has a resolution of 167 ppi and the Paperwhite has a resolution of 300 ppi.
I don't care about the backlighting since I use a lamp. So the only question is, is the resolution on the Kindle bad for my eyes? Is it really better to have a higher res screen?
Here's a comparison of 300 ppi (Voyage, Oasis, 2015 Paperwhite) vs 221 ppi (2014 and earlier Paperwhite) vs 167 ppi (Classic Kindle).
Actual dimensions seem to be
The 300 ppi can legitimately claim to be nearly indistiguishable from paper to my eye, once you factor in the natural fuzziness of eInk and the 16 shades of grey.
I think it's always better to have a good resolution. It's not a problem if you are reading ePubs. But when reading PDFs, I feel it is very hard to continue because I feel tired with low resolution. If the resolution is low and I try to read zoomed out, then my eyes can really feel tired.
Even when the resolution is high, don't read too tiny letters for a long time. If you do so, you may unknowingly take the device very close to your eyes and blur your vision.
Even if you have a back light in your device, it is always better to read with a lamp because when we read in the dark with a back light, the pupils of the eyes automatically adjust to the dark, but we are sending more light than the retinas expected.
Is the resolution on the Kindle bad for my eyes?
NO.
The resolution is fine for your eyes and for any eyes for that matter.
The question should be: Do you care for the resolution of the Kindle?
And the answer to this question depends solely on you. I despise low resolutions, they're an eyesore for me, so I had to had the Paperwhite. My girlfriend on the other hand, either doesn't care or can't spot a major difference most of the time. So she has the low res Kindle and she's perfectly happy with it.
Resolution is neither good nor bad for your eyes—all a lower resolution will do is make your text more jaggedy and less aesthetically appealing, which will be exacerbated at large font sizes. For reference, most print books are in the 200–300 dpi range. Books on glossy paper can be higher dpi (because the ink doesn't soak in as readily).
Basically, higher dpi will make your text crisper (to a point), but if that's not a big deal to you, you'll be fine. For reference, most of the web is still at 72ppi.
There are lots of filters that you can add for free that make this easier to answer. I use kindle fire and a bluelight filter. This has way more to do on your eyes than the res. Here is the skinny on all the research. I use Twilight on my Kindle and F.lux on my pc and my tablet. I hope this helps, also there is an eye health app on android that you can get

answer is No. specially if you want to read a simple text document I assure they are all identical (add Voyage to your list).
there are many comparison in internet, just google name of both devices and look at google images.
maybe it is unrelated, but I suggest you to go for pw because back-light makes it even easier to read during the day. amazon occasionally give discount for pw for price as low as 100€ so I would say it definitively worth it.
Having upgraded from Kindle to Paperwhite I have both and still use both. For reading after dark I use the Paperwhite and its backlight but I carry my Kindle with me for reading in the day. I find no problem with the difference in resolution though I prefer the higher resolution.
