Swimming for ordinary people, is a very good exercise, but for myopic people, there are a lot of things to pay attention to. Since they can't wear glasses in the water, swimmers often buy special protective goggles. Can anyone else wear contact lenses to swim?
As usually, swimming with contact lenses is not allowed unless the water in the pool is absolutely clean and sanitary. But in fact, neither private nor public swimming pools can meet this requirement. Chlorine and other chemicals are injected into pools to disinfect them, but contaminants such as sweat, hair, dander, cosmetics and some residual bacteria remain. Usually, the irritation of these substances to the eyes is transient, so the eyes will turn red after swimming, but they will recover after a while. But wearing contact lenses can affect lens quality, reduce corneal resistance or make your eyes less sensitive to light.
If you're in a natural body of water, such as seawater or a lake, the water contains more microbes and contaminants because it's not chemically treated. In such a place to wear contact lenses into the water, the probability of bacterial infection will be greatly increased. Often wear contact lenses, cornea long-term stimulation, eyes are generally more sensitive, if in order to see clearly after swimming still wear contact lenses, it is likely to cause serious inflammation, and even cause corneal ulcers.
Perhaps some people think of contact lenses with the combination of goggles, feel good, but the air in the goggles is limited, and can not guarantee a complete seal waterproof, can also let bacteria. Therefore, to prevent an increased chance of infection, be sure to remove your contact lenses before swimming.
