Sensitivity to Fluorescent (Blue-Green) Light

Polymorphous Light Eruptions

“…Control tests with Corex D filtration indicated that these reactions were caused by phototoxic rays not present in the nat¬ ural sunlight spectrum that reaches the earth's surface. 5. The significance of these findings was discussed in relation to the action spectra, wavelength dependency, and energy require¬ ments involved in patients with polymor¬ phous light eruptions.…”

“…The bulk of evidence to date indicates that the sunburn spectrum is responsible for the majority of these reactions.1-4 In a few cases longer wavelengths appear to have been responsible. 2,5,6 Whether this longer wavelength group should be included in the polymorphic category is open to question. This study was designed to establish accurately the action spectrum and energy requirements necessary to reproduce the polymorphous light reactions under controlled conditions in 29 patients suffering with this disease.…”
