Ophthalmic Prism Bar Set – Horizontal and Vertical Eye Alignment Testing Prisms

The Ophthalmic Prism Bar Set is a precision optical diagnostic instrument designed to measure ocular misalignment, assess binocular vision and evaluate strabismus and heterophoria. The set typically consists of horizontal and vertical prism bars with graduated prism powers, allowing eye care professionals to measure deviations during prism cover testing and other binocular vision assessments. Manufactured from optical-grade glass or acrylic, the prism bars are suitable for eye hospitals, ophthalmology clinics, optometry centres and orthoptic departments.
