Book Synopsis An Operational Evaluation of Extended-Wear Soft Contact Lenses in an Armored Division by : William G. Bachman
Download or read book An Operational Evaluation of Extended-Wear Soft Contact Lenses in an Armored Division written by William G. Bachman and published by . This book was released on 1987 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to evaluate the safety and military effectiveness of wearing contact lenses in an operational armor environment. Male volunteers from eight battalions of an armored division at Fort Hood were extended-wear soft contact lenses (SCL's) or spectacles for up to six months. During this period, physiological and subjective measures were obtained, along with logistical and personnel support information. Three types of SCL's were worn: high, medium and low water content lenses. Subjects followed their normal training schedule in garrison and on training ranges. Seventy-four percent of those successfully fitted with SCL's wore their lenses for the duration of the study, when administrative losses were factored out. More than a third of the SCL wearers experienced one or more ocular conditions requiring at least a temporary suspension of lens wear. A large majority of contact lens wearers indicated that SCL's improved their vision and job performance. These results represent the beginning of a database intended to address a variety of operational settings, environmental factors and job demands.
Book Synopsis A Field Study on Soft Contact Lens Wear in USAF Military Transport Aircraft by : Richard J. Dennis
Download or read book A Field Study on Soft Contact Lens Wear in USAF Military Transport Aircraft written by Richard J. Dennis and published by . This book was released on 1988 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contact lens wear as an alternative to spectacles for the correction of refractive errors in USAF aircrewmembers remains a controversial issue. Military transport aircrew must contend with reduced oxygen levels (typical cabin pressures of 5,000 to 8,000 ft), low relative humidity (10-15%), cigarette smoke, and fatigue and stress on long missions. Ten subjects wearing soft contact lenses and 6 control subjects not wearing contact lenses were evaluated visually and with a slit lamp onboard a C-5 aircraft on a routine mission to PACAF. Soft contact lens wearers noted no significant loss of visual acuity or contrast sensitivity during the flights. Some measures of corneal physiological stress (conjunctival injection, tear debris, etc.) were evaluated in both contact lens wearers and controls. Lens dehydration from the low relative humidity may have been the primary cause of the corneal physiological stress in the contact lens wearers. The results indicate that although there are increased physiological stresses on the cornea in the aircraft environment, there was not sufficient degradation in visual performance or lens comfort to preclude soft contact lens wear in military transport aircraft. Keywords: Soft contact lens, Aviation, Altitude, Cornea, Relative humidity, Visual acuity, Contrast sensitivity. (KT).
Book Synopsis Routledge Handbook of Research Methods in Military Studies by : Joseph Soeters
Download or read book Routledge Handbook of Research Methods in Military Studies written by Joseph Soeters and published by Routledge. This book was released on 2014-06-27 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume offers an overview of the methodologies of research in the field of military studies. As an institution relying on individuals and resources provided by society, the military has been studied by scholars from a wide range of disciplines: political science, sociology, history, psychology, anthropology, economics and administrative studies. The methodological approaches in these disciplines vary from computational modelling of conflicts and surveys of military performance, to the qualitative study of military stories from the battlefield and veterans experiences. Rapidly developing technological facilities (more powerful hardware, more sophisticated software, digitalization of documents and pictures) render the methodologies in use more dynamic than ever. The Routledge Handbook of Research Methods in Military Studies offers a comprehensive and dynamic overview of these developments as they emerge in the many approaches to military studies. The chapters in this Handbook are divided over four parts: starting research, qualitative methods, quantitative methods, and finalizing a study, and every chapter starts with the description of a well-published study illustrating the methodological issues that will be dealt with in that particular chapter. Hence, this Handbook not only provides methodological know-how, but also offers a useful overview of military studies from a variety of research perspectives. This Handbook will be of much interest to students of military studies, security and war studies, civil-military relations, military sociology, political science and research methods in general.
Book Synopsis Contact Lenses in the U.S. Army Attack Helicopter Environment by :
Download or read book Contact Lenses in the U.S. Army Attack Helicopter Environment written by and published by . This book was released on 1990 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent technological advances have had a major impact on military aviation. While modern methods of providing visual information via electro- optics/visionics systems have extended the aviator's operational envelope, these devices are becoming increasingly incompatible with spectacle wear. Since approximately 20 percent of Army aviators are ametropic (spectacle wearing), alternative means of providing a refractive error correction need to be investigated. One alternative being considered is the use of a contact lens correction. For the past year, the U.S. Army Aeromedical Research Laboratory (USAARL) has been conducting a worldwide, AH-64 Apache contact lens research project in order to develop a comprehensive database on contact lens wear in a variety of environments. A three-tier contact lens fitting system is being used: two different types of soft lens and one rigid gas permeable (RGP) lens type. The wearing schedule is set at a maximum of 7 days/6 nights of extended lens wear. Fundamental operational data is being chronicled by unit flight surgeons.
Book Synopsis The Use of Extended Wear Contact Lenses in the Aviation Environment: An Army-wide Study by :
Download or read book The Use of Extended Wear Contact Lenses in the Aviation Environment: An Army-wide Study written by and published by . This book was released on 1992 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: Standard refractive error correction options for the M-43 protective mask have proven to be incompatible with the Helmet Display Unit (HDU) component of the AH-64 Apache Integrated Helmet and Display Sighting System (IHADSS). Glue-on and outsert packages push the HDU, a Maxwellian- view virtual imaging system, far enough from the spectacle-, earing aviator's eye to significantly reduce the available field-of-view. Consequently, portions of critical peripheral instrumentation and weapon system overlays cannot be visualized. In November 1988, the U.S. Army Aeromedical Research Laboratory (USAARL) initiated the AH-64 contact lens research protocol to provide both an interim readiness fix and to develop a comprehensive database on contact lens wear in a variety of environments. The protocol was organized from three perspectives with concerns directed toward operational and flight safety, ocular health, and corneal physiology issues, and concluded at the end of September 1991. Fundamental operational and safety data were chronicled, along with written questionnaires, to assess subjective effectiveness of routine contact lens use. ocular health complications were collated from the aviation medicine, optometric, and ophthalmological communities. Clinical and physiological data were gathered by one USAARL optometrist, and two contract civilian optometrists and their supporting technicians.
Book Synopsis The Routledge Companion to Military Research Methods by : Alison J. Williams
Download or read book The Routledge Companion to Military Research Methods written by Alison J. Williams and published by Routledge. This book was released on 2016-04-28 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new handbook is about the practices of conducting research on military issues. As an edited collection, it brings together an extensive group of authors from a range of disciplinary perspectives whose chapters engage with the conceptual, practical and political questions raised when doing military research. The book considers a wide range of questions around research about, on and with military organisations, personnel and activities, from diverse starting-points across the social sciences, arts and humanities. Each chapter in this volume: Describes the nature of the military research topic under scrutiny and explains what research practices were undertaken and why. Discusses the author's research activities, addressing the nature of their engagement with their subjects and explaining how the method or approach under scrutiny was distinctive because of the military context or subject of the research. Reflects on the author’s research experiences, and the specific, often unique, negotiations with the politics and practices of military institutions and military personnel before, during and after their research fieldwork. The book provides a focussed overview of methodological approaches to critical studies of military personnel and institutions, and processes and practices of militarisation and militarism. In particular, it engages with the growth in qualitative approaches to military research, particularly research carried out on military topics outside military research institutions. The handbook provides the reader with a comprehensive guide to how critical military research is being undertaken by social scientists and humanities scholars today, and sets out suggestions for future approaches to military research. This book will be of much interest to students of military studies, war and conflict studies, and research methods in general.
Book Synopsis Use of Contact Lenses for Cold Weather Activities by : James F. Socks
Download or read book Use of Contact Lenses for Cold Weather Activities written by James F. Socks and published by . This book was released on 1981 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Military personnel are stationed in a wide range of geographical locations, some with adverse climates. Little is known about the effects of extreme cold on the cornea and on the ability to wear contact lenses. A survey was taken of contact lens wearers who commonly wear their lenses while engaged in outdoor activities. Although no serious problems were reported, redness of the eyes was the most common complaint of hard lens wearers; soft lens wearers most frequently complained about decreased vision. Contact lenses were generally comfortable in the cold, but lens care is difficult. Since they do not fog and they offer protection from wind-driven ice and snow, contact lenses offer an important advantage over spectacles. (Author).
