How to Calculate Prism Imbalances

Prisms are a peculiar structure that can convert a beam of multicolored light to a single translucent one. A prism is a three-dimensional shape that refracts light and is also transparent. It is present in the eye to help us convert light into images. To balance the prism and form a structure in equilibrium take a few balancing steps.

Instructions

- 1
  Use the formula distance times power equals prism equilibrium. When this formula is equal, the lenses in the prism will refract correctly to deflect light.
- 2
  Find the power or light energy that is directed towards the prism. The idea is to determine the total power (spherical equivalent) in the given meridian. For example, assume a power of 10 diopters.
- 3
  Find the distance of the prism, which is the length of the corner of the prism to the base. Assume that it is 0.6 mm in this example.
- 4
  Solve to balance the prism. Continuing the example, 10 D * 0.6 mm = 6 D mm.
