Description
The Ophthalmic RAF Ruler (Royal Air Force Rule) by ASF Universal is a manual diagnostic instrument designed for evaluating binocular vision functions, specifically convergence and accommodation. This precision tool is widely used by ophthalmologists and optometrists to assess both objective and subjective convergence in patients, helping to identify conditions such as convergence insufficiency, accommodative dysfunction, and binocular vision anomalies. It provides a simple yet highly effective method for testing near and distance visual performance during routine eye examinations.The RAF Ruler features a 50 cm long measurement scale, calibrated in 1 mm increments, ensuring fine accuracy and repeatable readings. It includes a sliding mechanism that supports a rotating four-sided cube, each side containing different fixation targets used to measure accommodation and convergence levels. This allows practitioners to assess the patient’s ability to focus and align their eyes effectively across various distances. The design supports a complete evaluation of binocular vision flexibility, making it a valuable tool for both diagnostic and therapeutic applications.
Constructed from lightweight, durable materials, the ASF RAF Ruler is easy to handle and highly portable, ideal for use in clinics, hospitals, and optometry practices. Its compact, ergonomic design ensures comfortable operation for both practitioner and patient. Combining accuracy, portability, and practicality, this RAF Ruler remains a trusted standard in ophthalmic and optometric testing for visual function and binocular coordination.
