Fine A tight clean softcover, no markings throughout, NOT an ex-libary book: Author David De Angelis's search for a cure for nearsightedness was both professional and personal, since he suffered from the disease himself. About the BookAuthor David De Angelis's search for a cure for nearsightedness was both professional and personal, since he suffered from the disease himself. Today only, save on used books and help us reach 15,000 books sold to double the donations. Gerhard Kelch: The primary job of a spectacle lens is to correct defective vision – short-sightedness or long-sightedness, for example. Gerhard Kelch: Well, we at ZEISS invest a lot of money in the ongoing improvement of our lens designs and in adapting them to the changing lifestyles of spectacle wearers. If we are developing a new lens design – our latest product ZEISS Digital Lenses, for example, we start by analysing exactly what the new design should achieve. Gerhard Kelch: In the past, it was only possible to design and produce lenses using spherical or toroidal surfaces. Nowadays, we calculate 12,000 individualised progressive surfaces each and every day in our Aalen factory in Germany. BETTER VISION: One last question: What would you as a mathematician recommend to every spectacle wearer?
Gerhard Kelch: I firmly believe that clear, comfortable vision is so essential in our everyday lives that more importance should be attached to it.

An expert in muscular work dynamics, he discovered through extensive testing and an immersion in decades of scientific studies that working the extrinsic ocular muscles could preserve sight and re-educate the eyes toward better vision.
Which product incorporates more optical knowhow – a spectacle lens or a modern high-performance camera lens containing five individual optical elements?
It can also remedy other visual impairments such as astigmatism or a condition that the experts call presbyopia, or the increasing difficulty to focus at close range as we get older. And the movement of our eyes varies from one person to another, and every frame sits differently on everyone's face – with a different tilt angle, for example. A prescription lens has a different optical power toward the top or side of the lens than when we are looking straight-ahead. Our many years of experience in the field of optics – and not only in the area of spectacle lenses – provides us with an ideal foundation for our work.


For progressive lenses, we have to choose wearers who are over 40 and already experiencing their first difficulties focusing at close range, or who already wear progressive lenses.
Today, we can design aspherical and atoroidal surfaces and incorporate them in lenses in many different ways.
The measuring data we receive for the individual spectacle wearer – data privacy is guaranteed at all times, of course, – is essential for the production of each individual lens. Today, outstanding technologies permit us to create solutions that offer the ultimate in visual comfort. And since each eye is as unique as a fingerprint, it requires a customised visual analysis at your optometrist. He came to understand the importance of retinal defocus for transforming ocular refractive status. The design must therefore be optimised in such a way that the best possible correction is achieved at the top and the periphery of the lens.
Our products cover the entire process from the initial eye examination using our measuring systems to the production and coating of our lenses. After all, what good is even the most sophisticated design if it's totally worthless in everyday use?
Imagine a lens gets lost during transportation or is broken during subsequent wear, we have the wearer's data ready to hand and can produce the replacement lens immediately. So, I would recommend everyone to have their eyes regularly tested by an eyecare professional. In this book, the author shares both the science and the "secret"-progressive retinal defocus technique-of how he was able to reverse his own myopia. This must all be adapted to the wearer's prescription and to the fit and shape of the frame. The vast majority of the systems we use are products, instruments, techniques and software tools we have developed ourselves.
How You Can Prevent and Reverse Nearsightedness (Paperback ) These books are NOT available for reading online or for free download in or ebook format. Our goal is to provide spectacle wearers with clear, natural vision in all directions, not just straight-ahead. One example: we can now produce modern sports eyewear with wrap frames in such a way that the wearer no longer experiences peripheral blurring.
When adequately stimulated by the simple exercises presented in the book, ocular refractive capability leads to gradual strengthening of focusing capability and gradual decreasing of refractive error.

A camera lens features symmetrical optics and is produced with the same shape over and over again. Powerful computer technology now allows us to design individualised lenses with extreme precision on the basis of the data we receive from your optician – and all in a matter of seconds. The past three years have shown that there is now a trend towards larger frames, for example.

A tested, standardised procedure using questionnaires then helps us to optimise the designs and to decide between different versions of the product.
This fashion trend also affects our designs: a lens sits very differently in front of the eyes in larger frames. Official website of The, Hero, The Magic, The Power, The to Teen Power and The Book Series.
The performance of spectacle lenses is the result of many different optical surfaces of immense complexity.
Needless to say, we also need the best optical design software which we develop ourselves and constantly enhance with new data.
