I went for an eye exam at lenscrafters and the doctor made me look through the refraction machine at the eye chart.In my left eye she put a -0.75 lens and asked whether I could read the bottom line.At first, I instinctively said yes, but realized I couldn't make out the letters. However, she told me to blink several times and after that I could make out the letters but I mistook a G for a C or an O (I forget). She said that's common and prescribed -0.75 without even testing the -1.00 diopter lens. I don't think my glasses correct my left eye to 20/20. Should I go back?
>>> Does this happen often?
