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 Considerations in Contact Lens Use Under Adverse Conditions by : National Research Council
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.

Book excerpt: Contact lenses and spectacles were compared to determine their relative merits and applications. The contact-lens types studied were: (1) a plstic, fluid, corneal-scleral design; (2) a plastic corneal design; (3) a plastic, ventilated, fluidless corneal-scleral design, and (4) a glass, ventilated fluidless cornea-sclreal design. The fluidless, ventilated lens proved superior to either the fluid or corneal type. The plastic lens appeared to offer greater protection of the eye since the lens is not easily broken. The major objection to plastic was attributed to poor wetting properties. In general, the contact lenses offered advantages in military field activities but were not superior in performance to spectacles in routine and clerical work. Contact lenses appeared particularly advantageous for use in inclement weather, arctic duty, swimming and violent activity. Corneal clouding was no longer a problem with the newer designs.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Conducting the Global War on Terrorism (GWOT) and projecting United States (US) influence worldwide has meant an increasing number of US diplomats and military forces are assigned to locations around the world, some of which have not previously had a significant US presence. In the current security environment, understanding foreign cultures and societies has become a national priority. Cultural understanding is necessary both to defeat adversaries and to work successfully with allies.
