The Teller Acuity Cards is a test of grating acuity for infants, young children and individuals with disabilities utilizing a preferential looking technique. This test has an extensive evidence base in normative and clinical studies that provide a strong foundation for applications in ophthalmology, optometry, and developmental practice.
