Refractive-Errors Books

David's book is a very good one and it is a method (like john method) that CAN give you back your clear and sharp vision, other books just talk only about improvement of vision and to be independent from glasses. The book describes the ocular stretching which I believe to be the basis of any method that you will may choose (add also neck exercise and breathing exercise to it). Then when the muscles of your eyes become stronger you may start the retinal defocus with the plus lens. My advice for anyone who wants to clear their vision is to do the exercises first and then ask if it will work or not. Last december i was prescribed a -2.00 lens to wear full time and with consistent training I can now see 'not perfectly' but i have good visual acuity with a low -0.75D. I am certain that additional improvement is ahead and all depends on my commitment and tenacity. One thing remains to say is "thank you David"

This is the best practical book in the market so far for Myopic eye. The use of plus lenses glasses really made a difference.

Their are few excercises which need to carry out on daily basis. Plus if u take multivitamins from GNC which really make difference for better vision.
Low Myopic eye which is less than minus three can even reverse their problem by applying the skills.

I ordered David De Angelis's book, "The Secret of Perfect Vision," as soon as it was announced, and have been following the program now for just about six months now. The "secret" of the "Power Vision System" that David describes in his book is working for me. I will let you in on the "secret". It is threefold:

1. Thorough extraocular muscle stretching/strengthening/range of motion exercises
2. Rest/recovery intervals
3. Retinal defocus training (reading through a slight blur produced by wearing a reduced, or sometimes "opposite" prescription, or so-called "plus" lenses, for low myopes)

Although I was able to pass the driver's exam (twice) since I "threw away" my -1.50 D glasses 15 years ago, my vision still wasn't perfect. Under good indoor conditions I have been able to read the 20/40 line. Today I am reading 20/25 under the same conditions.

Over the years I have been using plus lenses to keep my vision from slipping (I work at the computer all day), sometimes more, sometimes less intensely. In the past I have always reached a point of maximum improvement, where instead of improving with the plus lens, I felt my eyes simply got more tired. So I gave it a rest for a while, coming back to it when I became unsatisfied with my distance vision again. Basically, one step forward, one step back.

With the muscle exercise routine added, it seems more like four steps forward, three steps back. So it still isn't an "instant" cure, but I am noticing overall, gradual progress. My outdoor daytime vision is now excellent; it tests at 20/20 or even 20/15 in bright sunlight.

I feel that extraocular muscle exercises have "unlocked" my eyes, and now the exercises with plus lenses can "open" them up where they weren't able to before.

Although this book is quite long, its value is in the simplicity of the method presented. David spends a lot of time going over the scientific underpinnings of the method, from experiments with monkeys wearing lenses to the principles of exercise physiology. He puts it there, I think, mostly for the people who insist on having "proof." He warns you that there will be good days and bad days; you have to stick on through it. For some people, having a "scientific" explanation will give you the courage do persevere. Others, I must admit, might find the "science" part confusing, but it is really not necessary. For balance, David touches on emotional aspects of vision, which may resonate better for other readers. At the end of the book he has a practical question and answer section and specific very easy-to-follow routines.

And if you still have some questions, David provides a link to the free "PowerVisionForum" web site (full disclosure: I am the moderator) where you can discuss this method (and other methods of vision improvement) and David (or I) will happily answer them there.

I have read this updated edition of the book and also know the previous version. I recommend it to anyone willing to improve their nearsightedness, farsightedness or astigmatism. When I first started doing the exercises described in this book my prescription was -2.25/-2.5. Well, after constantly practicing my vision has improved and now my nearsightedness is -0.50/-0,75...amazing! The same exercises and principles can also be applied for prevention purposes and the author can be contacted for further questions. Highly recommended!

This book is designed to give those who are already competent with retinoscopy, a more (slightly - only 31 pages of actual book) in depth look at "near" retinoscopy only, not any other kind - plus a brief overview of some different methods of performing it. This book will not teach you how to perform retinoscopy and will be difficult to understand if you don't already have at least 9/10 of the scope on retinoscopy already. It does have some interesting reflex facts - but over-all I didn't find the book helpful.
