The use of contact lenses by firefighters is currently prohibited. However, many firefighters may benefit from this form of visual correction, without predisposing themselves to additional risk. Visual benefits gained by contact lens wear may increase a firefighter's safety. To determine if it is safe to allow firefighters to use contact lenses 29 were fitted with soft contact lenses and 21 with rigid gas permeable contact lenses. Questionnaires were completed prior to fitting, after 1, 4 and 10 months of contact lens wear. Both soft contact lens (SCL) wearers, and rigid gas permeable contact lens (RGPCL) wearers showed a statistically significantly reduction in the frequency with which they experience irritable foreign bodies and irritant fumes in the eyes, compared to not wearing contact lenses. Firefighters felt that their performance on the fireground had been improved by the use of contact lenses. SCL wearers also benefited from a reduction in the frequency with which they experienced watery eyes and ocular discomfort. There were significantly fewer problems encountered with SCL wearers than RGPCL wearers. The frequency with which firefighters experienced lenses falling out, lens displacement, watery eyes, ocular discomfort, and operational difficulties was significantly less for the SCL group than the RGPCL group. SCL appear to offer considerable benefits for firefighters with refractive error, but their use cannot be sanctioned without assessment of their effect on the ocular adnexa.
目前禁止消防员佩戴隐形眼镜。然而，许多消防员可能会从这种视力矫正方式中受益，且不会使自己面临额外风险。佩戴隐形眼镜所获得的视力益处可能会提高消防员的安全性。为了确定允许消防员佩戴隐形眼镜是否安全，29名消防员佩戴了软性隐形眼镜，21名佩戴了硬性透气性隐形眼镜。在佩戴前、佩戴1个月、4个月和10个月后完成问卷调查。与不佩戴隐形眼镜相比，软性隐形眼镜（SCL）佩戴者和硬性透气性隐形眼镜（RGPCL）佩戴者眼中出现刺激性异物和刺激性烟雾的频率在统计学上均显著降低。消防员们认为佩戴隐形眼镜提高了他们在火场的表现。SCL佩戴者还受益于流泪和眼部不适频率的降低。SCL佩戴者遇到的问题明显少于RGPCL佩戴者。SCL组消防员镜片脱落、镜片移位、流泪、眼部不适和操作困难的频率明显低于RGPCL组。对于有屈光不正的消防员来说，SCL似乎有相当大的益处，但在未评估其对眼附属器的影响之前，不能批准使用。
