What happens if you swim with your eyes open underwater in a chlorine swimming pool?

Irritated eyes: The weak chlorine solution found in swimming pools is an irritant to the conjunctiva of the eye. This usually results in a slight burning sensation, redness and possibly some blurred vision.

Eye irritation: Chlorine is an eye irritant. It can create a mild chemical burn on the skin covering the white of the eye (conjunctiva) and the clear window of the eye (cornea). Although it is not dangerous, it is very uncomfortable. If you have sensitive eyes or are at a pool with a high chlorine level, wear swim goggles or a mask.
