abstract="Recent interest in the relevancy of near vision tests for presbyopic aircrew members has led to the development of a photographic cockpit model. This model is used to prescribe more accurately for flying personnel. Prescriptions can be evaluated by use of trial lenses. This allows the aircrew members to experience the effect of viewing instruments in the cockpit of a C-130 aircraft.<p /> <p>Language: en</p>",
