CIE 1931 color space. Gamut of the CIE RGB primaries and location of primaries on the CIE 1931 xy chromaticity diagram. The CIE 1931 RGB color matching functions normalized to equal areas under the curves. Multiplying the red and green curves by 72.0962 and 1.3791 respectively yields the actual color matching functions.
The Worth Four Light Test, also known as the Worth's four dot test or W4LT, is a clinical test mainly used for assessing a patient's degree of binocular vision and binocular single vision. Binocular vision involves an image being projected by each eye simultaneously into an area in space and being fused into a single image.
Perger prism. A Perger prism or Perger–Porro prism system is a prism, that is used to invert (rotate by 180°) an image. The special feature of this prism is that, like a traditional double Porro prism system, it manages this with only four beam deflections and has neither a roof edge with the accompanying phase correction problems, a ...
The Abbe–Koenig prism shares the phase correction problems with other roof prisms. Abbe–Koenig prism and other roof prism binoculars benefit from phase-correction coatings to minimize these problems and substantially improve resolution and contrast.
During prism adaptation, an individual wears special prismatic goggles that are made of prism wedges that displace the visual field laterally or vertically. In most cases the visual field is shifted laterally either in the rightward or leftward direction. While wearing the goggles, the individual engages in a perceptual motor task such as pointing to a visual target directly in front of them ...

Fisheye. A fisheye lens is an ultra wide-angle lens that produces strong visual distortion intended to create a wide panoramic or hemispherical image. [4] [5] : 145 Fisheye lenses achieve extremely wide angles of view, well beyond any rectilinear lens.
