Low Vision Devices Low Vision Testing Aids Full Set

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 target 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.
