Available in PDF, EPUB and Kindle. Book excerpt: Retinoscopy is an eye exam that determines the refractive error of the eye (long sighted, short sighted, astigmatism). A refraction test indicates the strength of the prescription needed for glasses or contact lenses. The new edition of this book provides a concise overview of clinical refraction. Presented in an easy to read format, it is divided into two main sections. The first part explains basic clinical procedures for routine refraction, beginning with an introduction to instruments and the procedure, followed by aspects of the test for different disorders including myopia (short sightedness), astigmatism, keratoconus and refraction in children. Section two provides in depth discussion on retinoscopy and correct use of the retinoscope. The second edition has been fully revised and updated to explain the latest advances in the field, and is further enhanced by clinical images and figures. Key points Practical guide to clinical refraction and retinoscopy Fully revised and updated second edition Explains basic procedures and instruments for refraction test and refraction in different ophthalmic disorders Previous edition (9789351520634) published in 2014

Available in PDF, EPUB and Kindle. Book excerpt: For years scientists turned to the CRC Handbook of Laser Science & Technology for reliable data on optical materials. Out of print for several years, that standard-setting work now has a successor: the Handbook of Optical Materials. This new handbook is an authoritative compilation of the physical properties of materials used in all types of lasers and optical systems. In it, scientist, author, and editor Dr. Marvin J. Weber provides extensive data tabulations and references for the most important optical materials, including crystals, glasses, polymers, metals, liquids, and gases. The properties detailed include both linear and nonlinear optical properties, mechanical properties, thermal properties together with many additional special properties, such as electro-, magneto-, and elasto-optic properties. Using a minimum of narration and logically organized by material properties, the handbook's unique presentation simplifies the process of comparing different materials for their suitability in particular applications. Appendices furnish a wealth of other useful information, including lists of the many abbreviations and acronyms that proliferate in this field. The Handbook of Optical Materials is simply the most complete one-stop source available for materials data essential to lasers and optical systems.

Book excerpt: Spent Matches explores the possibility that a few small paradigm shifts within the church might make the difference between extinction and effectiveness. In fact, taking a clue from the automobile industry, the church might be able to not only halt the rapid decay in attendance but also become an effective tool in achieving Jesus' final command. For instance, the Hybrid car has become the answer to Detroit's environmental and oil crisis issues. Finding the synergy between two technologies, gas and electric has created a new day for the auto industry. Likewise, Spent Matchesexplores how the church can find synergy between two seemingly competing thoughts: an invitation to come and a command to go. The Hybrid metaphor brings energy to the church's mission and an explanation to the age-old argument of Missional versus Attractional methods. Features include: Innovative ideas for growing the church Methods to reach those who may never have attended church Scripture passages that touch on the subject of church growth

Book excerpt: God invites us to judge and to help correct wrongs from a place of understanding. Sometimes we pre-judge a person based on our own biases and superficial experiences. We stifle dialog before the conversation even begins. If all we know is our own faith, and we never put it side-by-side with what others believe, our spiritual growth and commitments can be easily stunted. By truly listening and learning from those with different beliefs, we can broaden and deepen our kingdom commitments. It is possible to stand up for Jesus, to articulate our faith clearly as witnesses, and to defend our faith effectively, while at the same time not being perceived as judgmental. Christians need to be faithful witnesses to God who are willing to listen to people with drastically different stories. In those exchanges, when we suspend judgment and truly listen, we will find truth and beauty and goodness in some of the most unexpected places. We will also find that, if we truly listen, we may be given a chance to speak. Features include: Help for interfaith and intercultural dialog Thought-provoking questions for spiritual conversation or reflection

Book excerpt: Good vision is more than 20/20 on a Snellen visual acuity chart. The modern ophthalmologist understands that contrast sensitivity, near and distance vision, performance under light and dark conditions, and the brain's interpretation of input from the sensory apparatus, are all important elements in patients' quality of vision. In Quality of Vision: Essential Optics for the Ophthalmic Surgeon, ophthalmologist and optics expert Dr. Jack T. Holladay explores the elements of vision that lie beyond Snellen testing. He explains the Quality of Vision addresses: - Measuring and treating astigmatism in corneal and IOL surgery - The importance of correcting spherical aberration in cataract and refractive surgery - IOL calculations after refractive surgery - Promising approaches to the correction of presbyopia - Other practical topics the clinician can use every day Recognized as the leader in ophthalmic optics, Dr. Holladay incorporates practical aspects of daily practice into each chapter as he expertly explains the scientific principles, mathematical formulas, and theories behind these important issues. Additionally, Quality of Vision includes numerous color illustrations to provide visual representations of the text's key points. Dr. Holladay discusses what's on everyone's mind: - How to take the best measurements and perform the best calculations to ensure good outcomes in cataract and refractive surgery - How neural adaptation can improve outcomes - How today's excimer laser systems deliver excellent optical correction, and why tomorrow's systems will perform even better Quality of Vision: Essential Optics for the Ophthalmic Surgeon is the most complete and practical reference for ophthalmologists looking to increase their understanding of optical physics and their ability to deliver good vision to their patients after cataract and refractive surgery.
