After an attack on earth, all reflective surfaces become weapons to release monsters, causing a planet-wide ban on mirrors. Despite the danger, the demand rises, and 17-year-old Marty Callahan becomes a distributor in an illegal mirror trade—until he’s caught by the mayor's son, whose slate is far from clean. Both of them are exiled for their crimes to one of the many abandoned cities overrun by fog. But they soon realize their thoughts influence their surroundings and their deepest fears begin to manifest. With fast pacing and riveting characters, this is a book that you’ll finish in one sitting.

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

Since the mid-1990s Taiwanese artists have been responsible for shaping much of the international contemporary art scene, yet studies on modern Taiwanese art published outside of Taiwan are scarce. The nine essays collected here present different perspectives on Taiwanese visual culture and landscape during the Japanese colonial period (1895–1945), focusing variously on travel writings, Western and Japanese/Oriental-style paintings, architecture, aboriginal material culture, and crafts. Issues addressed include the imagined Taiwan and the "discovery" of the Taiwanese landscape, which developed into the imperial ideology of nangoku (southern country); the problematic idea of "local color," which was imposed by Japanese, and its relation to the "nativism" that was embraced by Taiwanese; the gendered modernity exemplified in the representation of Chinese/Taiwanese women; and the development of Taiwanese artifacts and crafts from colonial to postcolonial times, from their discovery, estheticization, and industrialization to their commodification by both the colonizers and the colonized. Contributors: Chao-Ching Fu, Chia-yu Hu, Yuko Kikuchi, Kaoru Kojima, Ming-chu Lai, Hsin-tien Liao, Naoko Shimazu, Toshio Watanabe, Chuan-ying Yen.

The IOL technical specifications, the clinical data, and the necessary clinical and surgical skills comprise the scientific foundation for achieving a "premium" refractive outcome. To consistently achieve patient satisfaction, however, requires mastering the art of patient and IOL selection, communicating and counseling effectively, and providing a "premium" patient experience. This is a nontraditional book in which multiple experts are separately asked to discuss controversial subjects in a reader-friendly format. There is balanced coverage of all of the available refractive IOLs, as well as those that may become available in the near future. A major emphasis is placed on avoiding and managing complications or potentially dissatisfied patients. There are more than 200 chapters that are organized into 14 major sections, over 300 images, 100 tables, and 12 sidebars that cover every aspect of refractive IOL clinical practice. This is a comprehensive educational resource addressing the most demanding and rapidly evolving area in cataract and refractive surgery today and the first book to cover both the clinical and nonclinical aspects of offering refractive IOL services.
