What is the optimal pH range for eye irritation control in pools?

The optimal pH range for eye irritation control in pools is primarily maintained between 7.2 and 7.8, which helps to ensure that the water is comfortable for swimmers and minimizes irritation to the eyes and skin. Specifically, a pH range of 7.5 to 7.6 is ideal because it is close to the natural pH of human tears (approximately 7.4), allowing for better comfort and a reduced likelihood of irritation during swimming.

Maintaining pH within this range also aids in the effective disinfection and sanitation of the water, as extreme pH levels can hinder the performance of chlorine and other sanitizers used in pools. Additionally, the specified range ensures that the water remains neither too acidic nor too alkaline, both of which could lead to discomfort and possible health issues for users.

In summary, the choice of 7.5 to 7.6 optimally balances comfort for swimmers while ensuring effective water quality management and sanitation within the pool environment.
