In the development of eye and face protection standards against biological hazards, it is important to consider that the eye and face protectors may be used in the outdoor environment, where ultraviolet (UV) exposure from the sun is much higher than indoors. Workers affected include paramedics, ambulance officers and clinical testing personnel.
Spectral transmittances (280-780 nm) were measured on eight face shields and one goggle of the types used in hospital and clinical environments, three overhead projector sheets and an occupational impact protective goggle. The UV and luminous transmittances were calculated according to the international and two national sunglass standards, and compared with the compliance requirements.
All the face shields and goggle lenses were made of variants of the same material. All the samples, including the overhead projector sheets, complied with the requirements of the sunglass standards (for normal conditions, in the case of the American standard).
Since all the lenses complied with the sunglass standards for UV protection, and there appears to be uniformity in the choice of materials in this product type, there is no need to make provision, as is the case for occupational eye and face protection standards, for protectors that do not provide UV protection. This makes labelling and advice to end users from eyecare and safety professionals much simpler.
在制定针对生物危害的眼部和面部防护标准时，需要考虑到防护器具可能在户外环境中使用，户外环境中的太阳紫外线（UV）辐射强度要远高于室内。受影响的工作人员包括护理人员、救护人员和临床检测人员。
对医院和临床环境中使用的八种面罩和一种护目镜、三种投影仪银幕和一种职业冲击防护护目镜的光谱透射率（280-780nm）进行了测量。根据国际和两种国家标准的太阳镜标准计算了紫外线和可见光透射率，并与合规性要求进行了比较。
所有面罩和护目镜镜片均由同一种材料的变体制成。所有样本，包括投影仪银幕，均符合太阳镜标准的要求（对于美国标准的正常情况）。
由于所有镜片都符合太阳镜的紫外线防护标准，而且这种产品类型的材料选择似乎具有一致性，因此无需像职业眼部和面部防护标准那样，为不提供紫外线防护的防护器提供规定。这使得眼保健和安全专业人员为最终用户提供标签和建议变得更加简单。
