The external surface of the eye is coated with a chemically complex thin tear film. This tear film is composed of multiple layers (water, protein, and lipid) that perfectly interact with each other not only to keep your eye lubricated, but also to keep your tear film from evaporating too quickly. Chemicals in pools, such as chlorine and saline, are used as disinfecting measures and can wreak havoc on the tear film, causing water from the film to evaporate, leaving the surface of your eye unlubricated and exposed to other chemicals and bacteria in the pool. Also, chlorine by itself can be a major irritant to the eye, resulting in a condition known as chemical conjunctivitis, an inflammatory condition that causes redness, irritation, itching, and tearing in the eye.

During the summer, swimming is an effective way to keep in shape. But if you are in the water for a very long time, the water in the pool can really hurt our eyes, it can cause eye diseases like pink eye. Because the water in the pool is chemically treated which is called chlorinated water, chlorine doesn't kill all the bacteria in the water. So when our face is underwater, that means all the contaminants including chlorine, dust,and bacteria can get up close and personal with our eyeballs. Which can lead to temporarily distorted vision. In most people, the symptoms will go away after a few minutes. But for older people, it can take several hours for your eyes to feel normal.So use lubricating drops to flush out the chlorinated water is very necessary.

Exposure to chemically treated water of any kind can temporarily affect the eyes, because when the cornea is submerged in water, its protective tear film is washed away. That leaves eyes vulnerable to bacteria lingering in chlorine-treated water, since some contaminants aren't killed by the trace levels of chlorine often used in pools.The tear film is our natural-defense mechanism.Tear proteins help reduce infection rates from bugs still floating in the water, and when that is gone, the cornea is vulnerable to anything.swimmers can get eye infections from bacteria in chlorinated water. Bacterial or viral conjunctivitis, also called pink eye, is the most common infection that can spread through pools. Pool chemicals don't address everything that lives in the water.
