Prentice's rule is a formula to calculate the amount of prism correction in a lens based on decentration and lens power. It can be used for prescribing, tolerance control, or determining unprescribed prism in eyeglasses.
Learn about the different types of optical prisms, such as dispersive, reflective, beam-splitting and polarizing prisms, and how they refract, reflect or split light. Find out how prisms are made of transparent materials like glass, acrylic or fluorite, and how they can create spectra, images or polarizations.
Learn about binoculars or field glasses, two refracting telescopes aligned to point in the same direction, allowing binocular vision. Compare different optical designs, such as Galilean, Keplerian, Porro and roof prism, and their advantages and disadvantages.
The prism cover test (PCT) is an objective method to measure ocular misalignment or deviation of the eye. It involves using prism bars, occluder, and targets to neutralise the deviation and record the angle and base of the prism.
Learn how to interpret and write an eyeglass prescription that includes sphere, cylinder and axis components. Sphere and cylinder specify the power of the lenses, and axis defines the orientation of the cylinder relative to horizontal and vertical.
Learn about the origins and development of optics from ancient times to modern days. Explore the contributions of Greek, Roman, Islamic, and European scholars to the fields of geometrical, physical, and physiological optics.
