前言 双焦软性角膜接触镜的应用,为老飞行员碰到的近视力问题提供了一种解决的可能。他们需要双聚焦眼镜矫正视力,但又不能戴眼镜,因为眼镜与飞机的观测系统有矛盾。本研究的目的是把双焦软性角膜接触镜与双焦眼镜进行比较,以便军队能够确定这种角膜接触镜的总的可接受性,以有助于满足老飞行员在需飞军用机时的视力要求。方法 20名从Fort Foreword Bifocal soft contact lens applications provide a solution to near-vision problems encountered by old pilots. They need dual-focus glasses to correct their eyesight, but they can not wear glasses because the glasses are in conflict with the plane’s observation system. The purpose of this study was to compare bifocal soft contact lenses with bifocal lenses so that the military can determine the overall acceptability of such contact lenses to help meet the needs of older pilots when flying to military aircraft Vision requirements.
