The Bi-Nasal Occluder, also known as a Bi-Nasal Ruler, is designed to help vision care professionals determine the appropriate degree of nasal occlusion for patients experiencing binocular vision and visual processing difficulties. Bi-nasal occlusion may be used in the management of patients with acquired brain injuries, including traumatic brain injury (TBI) and stroke, as well as patients experiencing double vision, amblyopia, esotropia, convergence excess, divergence insufficiency, and visual overstimulation or confusion. The Bi-Nasal Occluder helps practitioners determine the amount of nasal occlusion needed to reduce or eliminate symptoms. Its graduated measurements also allow for repeatable, precise placement of occlusion foils or tape on spectacle lenses. It can also be used as a guide for properly cutting and positioning Bangerter Occlusion Foils. Features Occlusion gradients from 85 mm to 30 mm Graduated in precise 5 mm increments Helps determine appropriate bi-nasal occlusion placement Supports repeatable measurement and positioning on spectacle lenses Can be used to cut and position Bangerter Occlusion Foils Made from durable frosted plastic UV-coated for added durability Instructions included An effective clinical tool for professionals who use bi-nasal occlusion as part of vision rehabilitation and binocular vision management.
