It combines an occluder (a cover) with prisms to quantify misalignment in prism diopters. It is commonly performed in optometry and ophthalmology clinics during strabismus and binocular vision evaluations. It is used in children and adults, including people with double vision, suspected eye turns, or post-surgical follow-up."}
