SÍMBOLOS LEA®

El SISTEMA DE VISIÓN DE PRUEBA LEA incluye los SÍMBOLOS y NÚMEROS LEA, y es el único sistema de prueba de visión completo que utiliza el mismo optotipo en todas las situaciones de prueba. Las pruebas básicas del Dr. Hyvärinen son para situaciones de detección y prueba que involucran a todos los niños y pueden usarse para realizar evaluaciones funcionales de la visión en niños y adultos con retrasos en el desarrollo y discapacidades. Las pruebas básicas del Dr. Hyvärinen evalúan la agudeza visual de cerca y de lejos, la sensibilidad al contraste, los déficits del campo visual, la visión cognitiva, la adaptación visual y la visión de los colores. La Academia Estadounidense de Pediatría incluye LEA SYMBOLS en su lista de pruebas recomendadas para evaluar la visión de niños en edad preescolar.
