Sunday night: I practiced open focus with the Snellen chart for about 15 minutes. I could read 10/100 at the beginning, and I could read 10/40 at the end. The 30 line was almost readable, but I couldn’t recognize any of the letters.
Monday night: I practiced open focus with the chart for about 20 minutes. My measurements changed from 10/100 to 10/40. Once again, I could almost read the 30 line, but I could not identify any of the letters with confidence. Also, if I tried to imagine the letters on the 30 line with my eyes closed, I was not able to do so. For the last few minutes, I just blinked lightly and breathed fully while looking at the letters on the 30 line. This seemed to clear the letters on this line the most, but not enough to recognize them. I will try this technique the next time I practice with the Snellen and see if it still gives me good results.
