A Search for a New Aircrew Spectacle Frame.
Abstract
The factors necessary for a spectacle frame to meet acceptability for aircrew use were defined. The rising price of gold used in the HGU-4/P frame triggered triservice consideration for a change in materials and configuration of the aircrew spectacle frame. Optyl, a thermosetting plastic, presented potential for spectacle frame use in worldwide climates, and a field test was conducted to explore that potential and its acceptability by service personnel. The results were favorable for the use of thermosetting plastic based on the result of the analysis of wide-ranging questionnaire responses by Air Force subjects, and the reactions of opticians assembling the spectacles. At the end of the test period the HGU-4/P metal frame scored somewhat higher on overall acceptability than the Optyl 1019 frame. (Author)
