You already know the basics about how to measure diopter equivalents for your eyesight, with the centimeter measurement.  

You probably already also know all the caveats here:  

  1. Centimeter reflects accommodated vision, which can be different from your true distance vision.  
  2. Measurement accuracy is key.  If you misjudge the blur point, your diopter equivalent result will not be accurate.  
  3. High myopia / small centimeters create a measurement accuracy challenge.  A very small amount of centimeter change equals a relatively larger diopter change.  
  4. Lighting and other factors will cause your centimeter results to change, even if everything else is done consistently and correctly (same is true of course, for diopters as well)

If you’re new to endmyopia and vision improvement, above may sound complicated.  It’s not though, actually.
