This is a very interesting book. It shed some light on the limitation of optometry. But, it replaces with a lot of alternative advice that is inaccurate. First, he comes up with a strange psychological theory that would explain why peoples eyesight deteriorated by either becoming myopic or far-sighted. If you became myopic, it is because you became scared of the outside world through a life changing event that you did not cope well. Thus, you are refusing to look at the outside world, because you are afraid of it. If you became presbyopic, you did it because you became angry at the world through another life changing experience you did not digest well. So, you just had it with the world, and you refuse to look at any of its details close at hand. This is all bogus.
The author also did many experiment that I tried to duplicate myself, but never could. He takes a bunch of people who are really myopic and orders them to take off their glasses , and then measures their visual prescription twice within the next 24 hours. I did that, using the testing devise he offers to measure your improvement in vision. Mine did not budge, yours will not either.
In a nutshell, you cant just take off your glasses and see. This is giving you false hope. And, he should be sued for false advertisement.
So, why am I giving it a 3. Well, here are some positive valuable information I got out of it:
1) Be skeptical of your optometrist measurement of your own prescription. It is not as accurate as you think;
2) I have learned to live with "under prescribed" glasses. I now use a prescription that is weaker than one I had 11 years ago. And, I wear these 90% of the time I am wearing glasses;
3) I have learned to actually not wear any glasses when I dont need to. I probably do that 10% to 20%, when I am home eating a meal with my family.
By doing points 2) and 3) as described above, I maintain my vision at its current level, and control the speed at which myopia would accelerate for someone my age. I watch my colleagues at work rushing to get a new prescription every single year or so. And, that is nuts. If we all did that, we would end up with glasses as thick as wine bottle bottoms within 5 years. If you are doing that, stop it right now. This book will give you the confidence to stop this vicious cycle.
