Another common cause of itchy eyes after showering is dry eyes. This condition is easily treated with eye drops. If itchy eyes after showering occur frequently and soap and dry eyes have been ruled out, then the cause is most likely water, according to the health website Medical News Today (UK).
Not only soap but also some impurities or chlorine in water can cause itchy eyes after bathing.
Tap water causes itchy eyes after bathing in the following cases:
People sensitive to chlorine
Domestic water is taken from natural water sources, so it will contain bacteria. Chlorine is added to the water to kill bacteria and pathogens. This process is called dechlorination. The amount of chlorine added to the water is still safe for human health.
However, some people are extremely sensitive to chlorine, which can cause irritation to the skin and sometimes the eyes. For the eyes, irritation is often caused by water running into the eyes or the steam from a hot shower.
The effects of chlorine are especially noticeable when swimming in a pool. People sensitive to chlorine will experience red, watery eyes and sensitivity to light within a few hours of swimming.
Water with impurities
The condition of itchy eyes after bathing due to impure water often occurs in places where well water is used. Because water overflows on the ground when it rains, it will gradually seep into the ground. As a result, the water can contain pesticides, high levels of minerals such as calcium and magnesium.
These substances in water, when in contact with the stearic acid in soap, will create a residue and less foam. This residue will cause itching if it accidentally gets into the eyes. Even without soap, the minerals in water can cause eye irritation.
There are irritants in the water.
Municipal water is less likely to contain skin irritants because it is tested regularly. Well water can sometimes contain them. Irritants include not only pesticides and minerals, but also sediments, chemicals, and other chemical elements such as lead and nitrates, according to Medical News Today .
