These prisms fit standard trial
frames. They are made of optical quality acrylic and are lightweight. Each set
includes a display box. There are two sets available providing a full range of
prisms. The advantage of these prisms that is that a patient can wear the
prism with the trial frame while in the office to allow the patient to adapt
to the use of the prism. Patient feedback will be much better compared to
getting a quick patient reaction to the loose prism held in front of the
proposed correction.
