“…Because some of these agents have other ocular side effects, it has been proposed that some of these effects are due to their phototoxic abilities. However, the task of relating any effect to a photosensitizing mechanism continues to be dif cult (Dayhaw-Barker and Barker 1986).…”

Except when sleeping, the cornea and interpalpebral conjunctiva are exposed to the ambient environment, both natural and man-made. Levels of solar ultraviolet irradiance reaching the eye may exceed the damage threshold under a number of circumstances. The consequences of overexposure may be acute after a latent period, sequelae to an acute exposure, or long-term chronic effects. Previously derived action spectra for photokeratitis and photoconjunctivitis due to incoherent ultraviolet are presented. These reveal interspecies similarities for the levels of radiant energy reaching each tissue. The initial in vivo (clinical) signs of photokeratitis are due to lost or damaged epithelial cells with other signs produced by this primary response. The conjunctival signs include injection and chemosis. Chronic exposure to solar ultraviolet is a factor in climatic droplet keratopathy and pterygium. Phototoxic compounds or their by-products potentially can reach the cornea from the air, via the tears or aqueous humor, or from the limbal capillaries. However, the human cornea appears to be much less susceptible to the influence of phototoxic agents than the skin.

SUMMARY Eye (1992) 6, 166-172This article is divided into three sections. First, the data on the neonatal light dose is summarised. Second, the mechanisms by which light may affect the eye will be con-.sidered and third, we mention clinical conditions in which light has been implicated as a factor. NEONATAL LIGHT DOSEThe amount of light reaching the eye is governed by two groups of factors. First, physical factors: the intensity, spectral characteristics, and duration of light exposure. The high dependency regions in four of the seven units were significantly brighter than their corresponding low dependency nurseries at all times. In two of these units there is a policy of reducing the level of artificial light in
