Abstract

IN THIS review, ultraviolet radiation refers to the spectral region from approximately 300 to 400 mμ; in other words, the near ultraviolet rays. In many textbooks the visible spectrum is said to end at 400 mμ, and the ICI (International Commission on Illumination) luminosity curve does not extend beyond 380mμ, but shorter wave lengths than this have been reported to be visible on several occasions. The biological effects of the wave lengths of about 300 mμ are well known; they produce erythema and, in the eye, photophthalmia. Although it is generally recognized that the shorter wave lengths cannot penetrate to the retina, it is suggested that those between 300 and 400 mμ can have a harmful effect on vision. It is the purpose of this review to discuss the visibility of this band of the spectrum and its possible effects upon visual function. The reader should look elsewhere1 for
