No, I don't do any eye exercises, though I do believe that would help me get to the 20/20. In contact strength, I was 2.0 and 1.75. I wasn't tested for glasses in that eye exam, so I'm not sure where I stand now. I was tested during my annual physical, and both vision scores were based on my eye exams during my annual exam at the same facility.
I'm attaching a pretty good link about nutrition and vision. Maybe it can help.
Oh, I forgot to mention, I was using the E about a week and the A a few days when I started seeing results. However, I have been supplementing nutrients for months, in general, and this may have just been an important link to the whole.
