A study was undertaken to determine whether involuntary user movement provides a basis for relaxing the measurement conditions for evaluating the potential optical radiation hazards to the eye from slit lamps and indirect ophthalmoscopes. This was accomplished by assessment of the extent to which light from these devices can be maintained in focus on a 1-mm-diameter fiber-optic cable for 45 s. The results suggest that, although involuntary user movements can be significant, they do not provide a basis for relaxing the measurement conditions for evaluating the potential optical radiation hazards to the cornea and lens from slit lamps and indirect ophthalmoscopes.
开展了一项研究,以确定非自主性的用户移动是否为放宽评估裂隙灯和间接检眼镜对眼睛潜在光辐射危害的测量条件提供依据。这是通过评估来自这些设备的光能够在直径1毫米的光纤电缆上保持聚焦45秒的程度来实现的。结果表明,尽管非自主性的用户移动可能很显著,但它们并不能为放宽评估裂隙灯和间接检眼镜对角膜和晶状体潜在光辐射危害的测量条件提供依据。
