What is a potential limitation of glare testing?

Variability in individual patient responses to glare is a significant limitation of glare testing. Different patients may have varying levels of sensitivity to glare due to factors such as age, the presence of ocular conditions, or individual differences in visual perception. This variability can affect the reliability and consistency of glare test results, making it challenging to compare outcomes across different patients or to establish a standard threshold for normal versus abnormal sensitivity.

While other aspects, such as the need for specific technology or the lack of qualitative assessments, are relevant to the testing process, they do not capture the inherent subjectivity present in patient responses to glare. Understanding that individuals may react differently to glare can help in interpreting the results of these tests and tailoring patient management effectively.
