Monitoring the pH level of the eye is significant primarily because it can indicate the presence of an infection or irritation. The eye maintains a specific pH range, typically around 7.4, which is crucial for its health. When there is an imbalance—often due to infection, inflammation, or irritation—the pH level can change. For example, certain bacterial infections can lead to more acidic conditions, while irritations can affect the pH as well. By assessing pH levels, eye care professionals can gather valuable diagnostic information, which helps in identifying underlying issues and determining appropriate treatment options.

In contrast, while pH levels are important for general ocular health, they do not directly determine refractive error, measure tear production, or help in deciding lens prescriptions. Each of these aspects relies more on different evaluations and tests specific to vision correction and tear film assessment rather than pH measurement.
