Effects of Ultraviolet Radiation on the Eye, nm wavelength range, which has therefore been labeled the ., or “.” The maximum of the eye’s spectral response corresponds roughly to the maximum of solar spectral irradiance. Because solar UV radiation is present during most of the daylight hours, the eye may be exposed daily to some amount of solar ultraviolet radiation throughout life.

The Spectrum of Electromagnetic Radiation: UV-A in Perspective,is radiant energy is called . because it is in the form of oscillating electric and magnetic fields. Electromagnetic radiation exhibits both wavelike (oscillating field) and particlelike (discrete packet) properties. These discrete packets, or quanta, are called .. The number of oscillations per sec

Radiometry of Ultraviolet Radiation,ture in photo-biology lacks adequate, and occasionally any, measurement of the radiation. This is no longer acceptable. Recent advancements in electro-optics technology have produced readily available, versatile, and relatively precise ultraviolet radiometry equipment. This chapter reviews radiometr

Optical Properties of the Skin and Eyes,is absorbed. The biologic effects and microscopic alterations observed after absorption of UV radiation result from a complex sequence of biochemical reactions and cellular responses, some of which may be distant from the site of absorption. These chains of events must begin, however, with the excit

Immediate and Short-Term Biologic Effects of Ultraviolet Radiation on Normal Skin,iophysical and photochemical molecular events are followed by alterations in biochemistry and subsequent changes in cell metabolism. Electron-microscopic and histochemical studies demonstrate changes in cell structure and function occurring in minutes to hours after UV exposure. Subsequently, produc

Adverse Cutaneous Reactions to UV-A,, by indicating likely chromophores, may lead to an understanding of etiology and pathogenesis. A classical example of such a sequence was the identification of erythropoietic protoporphyria. and its separation from the polymorphous light eruption group. Second, photoprotective agents ideally are se

Effects of Ultraviolet Radiation on the Eye,agnetic spectrum provide a constant detailed map of our immediate environment. The action spectrum for this response lies primarily within the 400–700 nm wavelength range, which has therefore been labeled the ., or “.” The maximum of the eye’s spectral response corresponds roughly to the maximum of
