If you’ve ever forgotten your goggles and decided to make like a fish and open your eyes underwater, you may have been putting yourself at greater risk than you realize. Indeed, opening your eyes underwater increases the risk of a few types of eye irritation and damage.
In studies examining the eye effects of public swimming pools with , red eyes, irritation, and itchiness are . done in Italy found that even exposure to pool air was enough to cause ocular issues, as it does for the . In involving fifty non-goggle-wearing subjects who had their eyes examined immediately before and after swimming, 68 percent showed symptoms of corneal edema, and 94 percent showed some degradation in the covering of their cornea.
Chlorine-based compounds seem to be the main issue, with concentrations of just to the integrity of the corneal covering. Other methods of pool treatment, in particular , threat, but more research is needed. One of the prime culprits of eye irritation in a chlorine pool are monochloramines. They form when chlorine in the water reacts with organic substances like sweat or urine and are primarily responsible for the “pool smell.” One way to reduce their presence in pool water is by taking a pre-swim shower. Unfortunately, found that only roughly 35 percent of bathers took a shower when no sign was posted, even when showers were obviously available.
We might know to worry about potential infectious agents in lakes or ponds, but even indoor pools can harbor microbes, as evidenced by of 147 people infected with Pseudomonas aeruginosa after swimming in an indoor pool. Conjunctivitis, or pink eye, is also a common problem in swimming pools. In of 107 subjects, 21 percent had previously had swimming pool conjunctivitis. When asked what the cause was, 56 percent chose chlorine; in reality, most cases are due to adenovirus.
