In recent years, the study of polarisation vision in animals has seen numerous
breakthroughs, not just in terms of what is known about the function of this sensory ability …

The coupling of pyroelectric and photoelectric effects is a new method to enhance transient
response while maintaining steady-state response in photodetectors. Such photodetectors …

The dichroic macular pigment in the Henle fiber layer in the fovea enables humans to
perceive entoptic phenomena when viewing polarized blue light. In the standard case of …

Lutein, zeaxanthin, and meso-zeaxanthin (a steroisomer of zeaxanthin) are macular
pigments. They modify the physical properties of the lipid bilayers in a manner similar to …

Entoptic phenomena are visual artifacts arising from the interaction of light with the specific
anatomic structure of the human eye. While they are usually too subtle to actually enable …

Most polarisation vision studies reveal elegant examples of how animals, mainly the
invertebrates, use polarised light cues for navigation, course-control or habitat selection …

The ability to perceive polarization-related entoptic phenomena arises from the dichroism of
macular pigments held in Henle's fiber layer of the retina and can be inhibited by retinal …

Purpose: To optimize the perceptibility of Haidinger brushes (HB) and to investigate its
association with visual acuity and macular pigment density. Methods: In this prospective …
