Vision testing/training chart

Vision testing/training charts are reusable tools designed to assess and improve various aspects of eye function, such as visual acuity, accommodation, and convergence. Clinically, they help ophthalmologists and optometrists evaluate a patient’s vision, diagnose issues like refractive errors or binocular vision problems, and guide treatment or training exercises.

These devices are typically regulated as medical devices based on their intended use, with classification varying by jurisdiction. They are often supplied as standalone charts, cards, or digital displays, sometimes paired with accompanying instructions for use to ensure proper administration of tests or training protocols.
