To develop an algorithm for biologically effective cataractogenic irradiance of ultraviolet radiation corrected for spectral distribution of the source, age, and exposure time.
In current safety standards for avoidance of cataract after an in vivo exposure to ultraviolet radiation (UVR), the biologically efficient irradiance is estimated based on qualitatively determined spectral sensitivity and the spectral irradiance of the source. Recently, quantitatively determined spectral sensitivity, dependence on age, and dependence on exposure time, was published. Based on those data, we developed an algorithm for determination of biologically effective cataractogenic irradiance corrected for spectral irradiance of the source, age of the exposed individual and the exposure time.
The algorithm demonstrates that the biologically effective cataractogenic irradiance depends strongly on spectral distribution of the source, strongly on the age of the exposed individual and to some extent on exposure time. The biologically effective cataractogenic irradiance for a particular source, for an individual of a specific age and for a particular exposure time can be used for estimation of the Safe Exposure Duration (SED).
Safety standards for avoidance of UVR cataract should consider the spectral distribution of the source, the age of the individual exposed and the exposure time.
