Reflections of laser radiation from ophthalmological contact lenses are measured and hazard analysis calculations are presented. Measurements were made on the contact lenses using ophthalmic argon and krypton lasers. Reflection coefficients were around 0.2% for lenses with 'anti-laser' coatings and in the region of 4% for uncoated lenses. It can be shown that the nominal ocular hazard distance for a typical ophthalmic argon laser beam reflected from a contact lens with a flat front surface is approximately 30 cm for a coated lens and 1 m for an uncoated lens. The necessity of protective glasses for attending staff in particular circumstances is reviewed.
测量了眼科隐形眼镜对激光辐射的反射，并给出了危害分析计算结果。使用眼科氩激光和氪激光对隐形眼镜进行了测量。带有“抗激光”涂层的隐形眼镜的反射系数约为0.2%，未涂层的隐形眼镜的反射系数在4%左右。结果表明，对于从具有平坦前表面的隐形眼镜反射的典型眼科氩激光束，带涂层隐形眼镜的标称眼危害距离约为30厘米，未涂层隐形眼镜的标称眼危害距离约为1米。文中还讨论了在特定情况下医护人员佩戴防护眼镜的必要性。
