Affirmations by themselves are not programming. They prepare the way for programming; affirmations send a message to your brain that it is able to program to correct the problem. I was using Silva techniques to work on my eyesight and my other problems. The affirmations helped me to believe that my programming was working. As you can see, I incorporated a reinforcing mechanism into my affirmations.
You have to remember to keep your affirmations positive. It can be very tricky if you don't know what you are doing. Notice that I did not say "I have perfect eyesight." Why not? Because I knew that it wasn't true, and that would trigger a "reflex action" in my brain; it would respond with, "No they're not!"
I only used affirmations that I could believe at all levels. Here they are:
"Every day, in every way, I am getting better, better and better. "Every day in every way, my eyes are getting better, better, and better. "Every time I blink, my eyes are getting better, better and better. "Every time I blink, my eyes are getting clearer and stronger, stronger and clearer. "Every time I blink, my eyes get clearer, clearer and clearer. "My eyes are clearer today than they were yesterday. "My eyes will be clearer tomorrow than they are today. "Every day, in every way, I am getting better, better and better."
