Answers.Body: <p>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.</p>
  
  <p>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. </p>
  
  <p>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.  </p>

  <p><strong>NO.</strong> </p>
  
  <p>The resolution is <em>fine</em> for your eyes and for any eyes for that matter. </p>
  
  <p>The question should be: <em>Do you care for the resolution of the Kindle?</em></p>
  
  <p>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. </p>

Answers.Body: <p>Resolution is neither good nor bad for your eyes&mdash;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&ndash;300 dpi range. Books on glossy paper can be higher dpi (because the ink doesn't soak in as readily).</p>
  
  <p>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.</p>

Answers.Text: Most typesetting devices have a resolution greater than 1000 dpi; very few human eyes can discern differences above 500 dpi, and most books printed by offset have a resolution above 500 dpi. Also, I wouldn't say the web is at 72ppi — the web is dependent on the device YOU are using and you have to go back some years to hit display devices less than 100 ppi.
