Download or read book Considerations in Contact Lens Use Under Adverse Conditions written by National Research Council and published by National Academies Press. This book was released on 1991-02-01 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes current understanding of the scientific, clinical, and technical issues surrounding the use of contact lenses. It discusses the special occupational conditions experienced by military personnel, particularly in extreme environments, that give rise to the question of whether or not to use contact lenses. Experts in optometry, ophthalmology, visual psychophysics, and engineering describe recent developments in design and use; and representatives of the military services provide examples of actual situations in aerospace settings. Considerations in Contact Lens Use Under Adverse Conditions will be of particular interest to those involved in the design of contact lenses and those responsible for occupational safety and health matters in the private sector.
Download or read book Polarized Light and Optical Systems written by Russell Chipman and published by CRC Press. This book was released on 2018-07-16 with total page 1037 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polarized Light and Optical Systems presents polarization optics for undergraduate and graduate students in a way which makes classroom teaching relevant to current issues in optical engineering. This curriculum has been developed and refined for a decade and a half at the University of Arizona’s College of Optical Sciences. Polarized Light and Optical Systems provides a reference for the optical engineer and optical designer in issues related to building polarimeters, designing displays, and polarization critical optical systems. The central theme of Polarized Light and Optical Systems is a unifying treatment of polarization elements as optical elements and optical elements as polarization elements. Key Features Comprehensive presentation of Jones calculus and Mueller calculus with tables and derivations of the Jones and Mueller matrices for polarization elements and polarization effects Classroom-appropriate presentations of polarization of birefringent materials, thin films, stress birefringence, crystal polarizers, liquid crystals, and gratings Discussion of the many forms of polarimeters, their trade-offs, data reduction methods, and polarization artifacts Exposition of the polarization ray tracing calculus to integrate polarization with ray tracing Explanation of the sources of polarization aberrations in optical systems and the functional forms of these polarization aberrations Problem sets to build students’ problem-solving capabilities.

This book was released on 2012-12-06 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1958, on the occasion of the centenary of the Koninklijk Nederlands Gasthuis voor Ooglijders at Utrecht, the Snellen medal was founded by the Board of the hospital in memory of PROF. DR. HERMAN SNELLEN SR. This medal should be presented each 5th year to a person of Dutch nationality, who had exceptionally distinguished himself in the field of ophthalmology . The Snellen committee, of which I had the honour to be a member, was unanimous in their choice of the laureate of this award; it should be Dr. C.D. BINKHORST for his outstanding and ingenious work on the intra ocular implant lens. BINKHORST, an exceptionally gifted eye-surgeon, started lens implantation in 1955, after he had studied Ridley's method in London. "He introduced several improvements, and in 1957 developed his iris clip lens, in which fixation of the implant lens was provided by the iris diaphragm. The iris clip lens was followed in 1965 by the iridocapsular lens, intended for extracapsular extractions, while the iris clip lens was suitable for both intra capsular and extracapsular extraction. BINKHORST has earn ed a world reputation and ophthalmologists from all over the world come to the little towns of Terneuzen and Sluiskil in the province of Zeeland, to learn his technique.

Download or read book The Eye Pt IB written by Hugh Davson and published by Elsevier. This book was released on 2012-12-02 with total page 525 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Eye, 3rd Edition, Volume lb: Vegetative Physiology and Biochemistry deals with the vegetative physiology and biochemistry of the eye. The book reviews major advances in the anatomy of the eye and its physiological and biochemical aspects, particularly the cornea and sclera, the ordered state of the lens, and lens development, growth and regeneration. This edition is organized into three chapters and begins with an overview of the mechanical and optical properties of the cornea and sclera and their relationship to the underlying structure of the tissue. This book shows that, in the cornea, the maintenance of the tissue structure requires the constant action of a fluid transport system dependent upon metabolic energy. The pathways of corneal nutrition, the sensitive corneal innervation, and the growth processes in the cornea and sclera are also discussed, emphasizing the mammalian cornea. The next chapter examines the use of physical and chemical techniques to determine how the ordered state of the lens is maintained and why that state is susceptible to chaotropic attack. Finally, an account of the metabolism of the lens and how cataract forms is given. This book is a valuable resource for students and researchers in fields ranging from ocular science to physiology and biochemistry.

Download or read book Geriatrics 3 written by D. Platt and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 505 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 3 of this series is concerned with geriatric aspects of surgical specialties: gynecology, orthopedics, general surgery, otorhinolaryn gology, and ophthalmology. Closely associated with these specialties is anesthesiology. Dermatology has an intermediate position between surgical and nonsurgical fields. The peculiarities of physiological and pathological aging of otgans and the consequences for diagnosis and therapy - presented in the first two volumes - are of great significance, especially for surgical special ties. There are a large number of pre-, intra-, and postoperative problems in multimorbid geriatric patients, e. g. , coronary insufficiency, brady arrhythmias, hypertonia, and hypotonia. While as recently as the tum of the century the age of 65 years was viewed as a contraindication for sur gery, today even older patients undergo operations on aortic aneurysms, bypass operations for coronary sclerosis, pulmonary resections, and abdominosacral resections of rectal carcinomas, for example. Pre requisite for successful surgery at an advanced age is good pre- and postoperative care of multimorbid patients. Physiological changes of the lungs with aging, the increased frequency in pneumonia and pulmonary just a few embolisms with age, and the decrease in receptors, to give examples, confront anesthetists with difficulties. The maxim "in old age a little less" is also applicable in this field. Only improved experimental gerontological research, possibly reaching even into anesthesia, will provide objective data for anesthesia in elderly patients. The skin is an organ that experiences characteristic qualitative and quantitative changes in old age.
