About

Tilted Prism

Features

Read full description

This app simplifies the calculations and prescription for tilted prisms, resulting from the combination of a horizontal + vertical prism. This app facilitates the prescription od tilted prisms in cases of diplopia due to combined horizontal and vertical deviations. Starting with the patient's deviation measurements, the app calculates the resulting power of the combined prism, the resulting angle of the prism, and allows splitting of the resulting prism for both eyes, or the option to place it for a single eye (such as is used for Fresnel prisms).
