The title says it all. I can see the big ‘E’ on the Snellen chart without, which is about 20/200 and that roughly translates to -1.50. But I noticed when I measure my diopters through the distance to blur method (Jake’s inverse meters method), I get a much higher diopter number-- usually around -2.25. Thus my question: which is a more accurate measurement of your true eyesight? Snellen chart or distance to blur?
