Novel optical devices, which are referred to as composite prisms in this document, have been designed, produced and tested. They have the potential to be useful for a number of vision related applications. For high prism diopter (15 prism diopters or more), composite prisms have resulted in thinner, lighter and lower aberration optical devices than the standard ophthalmic prisms currently in use. They also offer significantly better optical quality than the Fresnel press-on prisms which are also used to correct several ophthalmic disorders.
