Can chlorine in swimming pools damage eyes?

When your eyes are submerged in chlorinated pool water, the tear film that usually acts as a defensive shield for your cornea is washed away. This means that your eyes are no longer protected from dirt or bacteria that are not entirely eliminated by the treated pool water. So, swimmers can be prone to eye infections.

Why can’t humans see underwater?

So, when we open our eyes underwater, incoming light rays are hardly bent, or focused, at all. The inside lens bends the rays a little, but it can’t make up for the lost corneal refraction, so the light that reaches the retina isn’t focused and the underwater world looks blurry.

Why is our vision blurred underwater?

Water, however, has approximately the same refractive index as the cornea (both about 1.33), effectively eliminating the cornea’s focusing properties. When immersed in water, instead of focusing images on the retina, they are focused behind the retina, resulting in an extremely blurred image from hypermetropia.
