The Accommodation Convergence Ruler is a clinical-grade instrument used by eye care professionals to measure a patient’s near point of convergence and accommodation. By sliding a t arget card along the marked ruler, practitioners can accurately determine how close the eyes can converge comfortably and assess focusing ability, helping to diagnose binocular vision disorders such as convergence insufficiency or accommodative dysfunction. Its clear, high-contrast graduations (in both diopters and centimeters) make readings quick and reliable, while the compact, lightweight design ensures easy handling in any exam room. In addition, the instrument includes a cube with four sides, each providing a different target for comprehensive assessment: Near point of convergence measurement Visus / Amplitude of accommodation measurement Amplitude of accommodation measurement Polarized balance measurement Ideal for optometrists, orthoptists, and ophthalmologists, this tool is an essential component in routine vision screenings and vision therapy programs.
