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. The test is cited more often than any similar product in the health information compiled by The National Library of Medicine.
Large Fixation Disparity Polarized Target vectographic two-dimensional card comes with 2 Fixation Disparity Crosses positioned vertical from one another introducing a new Fixation Disparity Cross design (bottom cross at 20/100 acuity level).
