On the possible sources of ocular irritation in chlorinated swimming pools

A case of superficial punctate keratitis caused by exposure to chlorinated swimming pool water is described. Although pool water tonicity, pH and a variety of chlorine species present in pool water may be implicated in such reactions, a review of the relevant literature revealed that very little is known about the true nature of these reactions. The wearing of swimming goggles as a preventative measure is the only recommendation which can be made based on current knowledge.
