  2. Prism correction - Wikipedia

    en.wikipedia.org/wiki/Prism_correction

    Other applications include yoked prism where the image is shifted an equal amount in each eye. This is useful when someone has a visual field defect on the same side of each eye.

  3. Prism (optics) - Wikipedia

    en.wikipedia.org/wiki/Prism_(optics)

    In contrast, spectacles with prisms of equal power for both eyes, called yoked prisms (also: conjugate prisms, ambient lenses or performance glasses) shift the visual field of both eyes to the same extent.

  4. Yoked control design - Wikipedia

    en.wikipedia.org/wiki/Yoked_control_design

    A yoked control design is a research design used in experiments in which matched research subjects are yoked (joined together) by receiving the same stimuli or conditions. In operant conditioning the yoked subject receives the same treatment in terms of reinforcement or punishment.

  5. Homonymous hemianopsia - Wikipedia

    en.wikipedia.org/wiki/Homonymous_hemianopsia

    Homonymous hemianopsia occurs because the right half of the brain has visual pathways for the left hemifield of both eyes, and the left half of the brain has visual pathways for the right hemifield of both eyes. When one of these pathways is damaged, the corresponding visual field is lost.

  6. Vision therapy - Wikipedia

    en.wikipedia.org/wiki/Vision_therapy

    Prisms for near binocular disorders and for producing postural change – the use of "yoked" prisms to redirect a person's gaze and bring about a range of claimed benefits including postural improvements and increased wellbeing.

  7. Prism (geometry) - Wikipedia

    en.wikipedia.org/wiki/Prism_(geometry)

    In geometry, a prism is a polyhedron comprising an n-sided polygon base, a second base which is a translated copy (rigidly moved without rotation) of the first, and n other faces, necessarily all parallelograms, joining corresponding sides of the two bases.

  8. Conjugate eye movement - Wikipedia

    en.wikipedia.org/wiki/Conjugate_eye_movement

    Conjugate eye movement refers to motor coordination of the eyes that allows for bilateral fixation on a single object. A conjugate eye movement is a movement of both eyes in the same direction to maintain binocular gaze (also referred to as “yoked” eye movement).

  9. Dispersive prism - Wikipedia

    en.wikipedia.org/wiki/Dispersive_prism

    Photograph of a triangular prism, dispersing light Lamps as seen through a prism. In optics, a dispersive prism is an optical prism that is used to disperse light, that is, to separate light into its spectral components (the colors of the rainbow). Different wavelengths (colors) of light will be deflected by the prism at different angles.

  10. Minimum deviation - Wikipedia

    en.wikipedia.org/wiki/Minimum_deviation

    This angle of incidence where the angle of deviation in a prism is minimum is called the minimum deviation position of the prism and that very deviation angle is known as the minimum angle of deviation (denoted by δ min, D λ, or D m).

  11. Wedge prism - Wikipedia

    en.wikipedia.org/wiki/Wedge_prism

    The wedge prism is a prism with a shallow angle between its input and output surfaces. This angle is usually 3 degrees or less. Refraction at the surfaces causes the prism to deflect light by a fixed angle.
