<p>This is the rule in question, (listed under the Death Note Wiki as "How to Use: XXI"):</p>

<blockquote>
  <p>"Those with the eye power of the god of death will have the eyesight of over 3.6 in the human measurement, regardless of their original eyesight."</p>
</blockquote>

<p>So, what are the numbers referring to? 3.6 what? I googled Visual Acuity, and I'm guessing those with death god eyes can see over 3 and a half times further than normal humans? 3.6 times to be exact. </p>

<p>I never read the manga, or saw the Japanese version, so I ask this question to confirm it with perhaps something someone read.</p>

3.6 in Japanese measurement is the equivalent of 72/20 in American measurement.
That's considered to be *Excellent* eyesight.

It's not that you see 3.6 times further, you are able to *distinguish*, 3.6 times more detail in the image you get (read, 3.6 times smaller details).
