Considering the Effect of Neural Adaptation in the Estimation of Haidinger's Brush Perceptual Threshold

The study confirms the crucial role of rotational speed in the perception of Haidinger's brushes, especially at low polarization levels. As a normal pattern perception correlates with macular pigment distribution and density, those findings are essential for the development and calibration of screening devices based on Haidinger's brush perception for the early detection of maculopathy and other macular diseases.
