This document describes visible solar radiation with wavelengths close to the UV range, its transmission to, within and the effects on the human eye.

This document describes visible solar radiation with wavelengths close to the UV range, its transmission to, within and the effects on the human eye. The wavelengths concerned are from 380nm to 500nm, covering the colours of violet, indigo and blue— often referred to as the \'blue wavelengths\'.

It also explains the filtering effects and measurement of spectacle lenses and sunglasses, thereby providing background information to understand the transmittance requirements related to filtering effects of lenses and filters in the available spectacle lens and sunglass standards.

This document does not address the issues of protection from artificial sources of radiation.

This document is intended to be of benefit to any future interest in ISOstandardization related to transmission of solar radiation with wavelengths near to and greater than 380nm.

The Bibliography provides a source of relevant useful references.
