Ultraviolet protection in eye and face protection against biological hazards.

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.
