Assessment of a Prototype Apache Flight Eyewear.

Background: Apache pilots needing refractive correction are issued modified HGU-4/P aviator spectacles. However, a recently published survey found field of view (FOV) dissatisfaction with the current spectacles when sighting in with a Helmet Display Unit (HDU). A current Air Force flight frame was modified in-lab and the purpose of this study was to evaluate the FOV with the current Apache flight frame vs.

A Performance Comparison of Color Vision Tests for Military Screening.

Background: Current color vision (CV) tests used for aviation screening in the U.S. Army only provide pass-fail results, and previous studies have shown variable sensitivity and specificity.

Assessment of an Alternative Army Aircrew Eyewear.

Background: Currently, Army aircrews needing refractive correction are issued the HGU-4/P aviator spectacles. However, a recently published survey found dissatisfaction with the current spectacle frame. The Aircrew Flight Frame (AFF) has been used by the Air Force for over 14 yr, with the AFF-OP (Operational) style used the longest.

Effects of repetitive low-level blast exposure on visual system and ocular structures.

Unlabelled: The purpose of this study was to determine whether repetitive exposure to low-level blasts during military breacher training produces acute and cumulative damage to the ocular tissues or visual system. The effects of low-level blast exposure on high-contrast visual acuity, contrast sensitivity, oculomotor function, color vision, visual field (VF), pupillary light reflex, corneal endothelial cell density (ECD), macular thickness, retinal nerve fiber layer thickness, and cup-to-disc ratio were assessed using a battery of standard clinical ophthalmic tests administered 10 times over a 2-year period. Data from nine breacher instructors (Cadre) were compared with data from four breacher engineers (CONTROL).
