The RAF Rule (Royal Air Force Rule) is a specialized instrument used in ophthalmology and optometry to measure the near point of convergence (NPC) and near point of accommodation (NPA)

This tool is essential for assessing binocular vision and diagnosing various visual disorders. The RAF Rule consists of a 50 cm long ruler with a slider that holds a rotating four-sided cube, each side featuring different targets and measurements

One side of the cube has a vertical line with a central dot for convergence fixation, while the other sides provide lines of near reading examples

The instrument is designed to measure objective and subjective convergence in 1 mm increments, making it highly precise

It also includes a cheek rest to ensure consistency and proper height during measurements

The RAF Rule is particularly useful for diagnosing and treating conditions related to binocular vision, such as convergence insufficiency and accommodative dysfunction

Studies have shown that the RAF Rule provides more consistent measurements of NPC compared to using a pencil or finger
This consistency is crucial for accurate diagnosis and effective treatment planning.

In clinical practice, the RAF Rule is used to determine the objective and subjective convergence points, examine accommodation, and identify the dominant eye

Its versatility and precision make it a valuable tool for both diagnosis and treatment in eye care
