The UV problem: have the rules changed?

: In summary, the increase in numbers and longevity of the population is clearly demonstrated by the census records. The facts that human behavioral patterns have drastically changed to permit ever-increasing exposure to sunlight is a matter of history. The changes in the environment will have a profound effect on the world in which we live. Our food supply could be severely disrupted, the incidence of skin cancer is likely to increase substantially, and ocular radiation trauma to the cornea, lens and retina will be expected to increase in prevalence. This alarming information has been acknowledged by the national press in the newspapers and magazines, and by the radio and TV networks. The attention has resulted in a striking awareness of the public to the UVR hazard. Likewise, the scientific community has devoted considerable attention to the harmful nature of UVR exposure to the skin and the eye. The brief survey of UV research presented in this paper consistently demonstrates that the cornea, lens and retina are all vulnerable to permanent UVR damage. Our survey of available facts indicates that the "rules have changed dramatically on all counts." Ocular protection against UVR exposure must be provided to our patients in the form of contact, ophthalmic or intraocular lenses. The additional cost of UV protection is insignificant when compared to the cost in visual loss over a lifetime. We are truly talking about trivial costs when UV protection is contrasted to what people spend on getting extra UV exposure at the solarium, spa, ski slopes, beach, mountains, etc.(ABSTRACT TRUNCATED AT 250 WORDS)
