The Freeman Occluderule is a versatile and essential tool for optometrists and dispensing opticians. Made from flexible, non-shrinking plastic, this multi-functional instrument is designed to assist with a variety of optical measurements and tasks
One of the primary uses of the Freeman Occluderule is measuring pupillary distance (PD), both frame and facial. Accurate PD measurements are crucial for ensuring that lenses are correctly positioned in front of the eyes, which is essential for optimal visual performance

In addition to its measurement capabilities, the Freeman Occluderule serves as an occluder for covering one eye during vision tests, a pointer for indicating specific points on charts or diagrams, and a near point fixation spot for assessing near vision
It can also be used as a near point convergence line, helping to evaluate the ability of the eyes to work together when focusing on close objects
The Freeman Occluderule is supplied in a convenient pouch with instructions, making it easy to carry and use in various settings
