Variety models of glare indices have been set up or are being studied by CIE. However, the lacking of guidance or standards in the aspect of the physical measurement hinders the wide application and comparison of the glare indices. At present, ILMD is internationally recognized as a good solution for glare measurement, but the performance of the ILMDs varies very much, which leads to difference results in glare evaluation. The paper investigates different types of ILMD and further uses the numerical simulation to study the sensitivity coefficients of the factors to the measurement uncertainty of glare indices, and the requirements of an ILMD can therefore be proposed properly so as to acquire acceptable accuracy of glare indices.
