The LEA 3-D Puzzle is designed for supporting the development of the concept of “same”, first with colors, then with black & white concrete forms that are prerequisites for the measurement of recognition acuity with the LEA SYMBOLS® tests at an early age.
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.
Sloan Letter charts calibrated to test visual acuity at an intermediate distance of 66 cm (26 in.).
This chart can either be wall mounted or used in an ESV 1200 , ESV 1500 , or a Model A illuminated cabinet.
