METHOD AND APPARATUS FOR PERFORMING VISION SCREENING

摘要

The present invention relates to a vision screening System and a method for using the System to perform screenings for vision disorders, including amblyopia in children. The System includes a lightweight, portable apparatus having a surface upon which a series of images are imprinted, projected, or digitally altered. The size, shape, appearance, and arrangement of the images are chosen to allow an examiner to detect an examinee 's visual acuity. The apparatus also includes a measurement tool, integrated with the apparatus, which enables the examiner maintain the surface of the device at a predetermined distance from the examinee's eyes (81). To screen a child's vision, the apparatus is positioned at a predetermined distance from the examinee's eyes. With one eye covered (80) at a time with provided adhesive patches, the examinee is asked to either identify an image (83) displayed on the apparatus, or point to a matching image on a card that is located at a close distance to the examinee. Based upon the examinee's collective responses (84), the examiner can determine whether the examinee is affected by a visual disorder.
