WebMay 9, 2024 · The Pulfrich Effect, which happens when a filter is placed in front of one eye, is an optical illusion in which an object which is moving in a plane parallel to the viewer's forehead seems to move out of the plane mentioned above. It looks as if the pendulum approaches (or recedes from) the viewer. The Pulfrich phenomenon (also known as the Pulfrich effect) is a neuro-ophthalmic observation in which two-dimensional (2-D) objects are perceived to be three-dimensional (3-D) due to slight discrepancies in signal transmission time between a set of eyes and the visual cortex . The relative delay in conduction … See more The Pulfrich phenomenon was first described in 1922 by Carl Pulfrich, an expert in stereoscopy . Pulfrich had named the phenomenon “stereo effect” but over time the phenomenon … See more While the Pulfrich phenomenon may have different etiologies, visual evoked potential (VEPs) may be used to confirm the visual latency that causes this effect . VEPs measure evoked … See more The Pulfrich phenomenon is a result of a delay in afferent signal conduction to the visual cortex . Thus, there are various etiologies behind this effect. A common pathology that displays the Pulfrich effect is demyelinating optic … See more The Pulfrich phenomenon can be treated by addressing the reversible causes of vision loss (e.g., cataracts) or by using a neutral density filter for irreversible causes (e.g., optic neuritis) . In some cases, the underlying etiology for … See more
