3. Prism correction - Wikipedia

   en.wikipedia.org/wiki/Prism_correction

   Prism correction. Prism lenses (here unusually thick) are used for pre-operative prism adaptation. Eye care professionals use prism correction as a component of some eyeglass prescriptions. A lens which includes some amount of prism correction will displace the viewed image horizontally, vertically, or a combination of both directions.

4. Crown glass (optics) - Wikipedia

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

   BAK-4 barium crown glass (glass code 569560) has a higher index of refraction than BK7, and is used for prisms in high-end binoculars. In that application, it gives better image quality and a round exit pupil. An achromatic doublet, which combines crown glass and flint glass.
