It becomes necessary to make the test task simpler than the letter chart task and, in order to achieve very large angular sizes, very close viewing distances may be required. In the interests of simplicity and flexibility of use, the BRVT has 3 card-pairs. Each card pair consists of two 25 cm square hinged cards so each card-pair has 4 target surfaces.\u003c\/p\u003e\n\u003cp bis_size='{\"x\":12,\"y\":218,\"w\":576,\"h\":19,\"abs_x\":428,\"abs_y\":480}'\u003e\u003ca href=\"https:\/\/storage.googleapis.com\/stateless-precision-vision\/2024\/12\/2fedd287-4500-instructions-rev3.1.pdf\" rel=\"noopener noreferrer\" bis_size='{\"x\":12,\"y\":218,\"w\":161,\"h\":18,\"abs_x\":428,\"abs_y\":480}' target=\"_blank\"\u003e\u003cspan style=\"color: #ff0000;\" bis_size='{\"x\":12,\"y\":218,\"w\":161,\"h\":18,\"abs_x\":428,\"abs_y\":480}'\u003eClick Here For Instructions\u003c\/span\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003cp bis_size='{\"x\":12,\"y\":253,\"w\":576,\"h\":19,\"abs_x\":428,\"abs_y\":515}'\u003e\u003ca href=\"https:\/\/storage.googleapis.com\/stateless-precision-vision\/2015\/05\/4500_BRVT-Testing-flow-chart.pdf\" rel=\"noopener noreferrer\" bis_size='{\"x\":12,\"y\":253,\"w\":246,\"h\":18,\"abs_x\":428,\"abs_y\":515}' target=\"_blank\"\u003e\u003cspan style=\"color: #ff0000;\" bis_size='{\"x\":12,\"y\":253,\"w\":246,\"h\":18,\"abs_x\":428,\"abs_y\":515}'\u003eClick Here for The Testing Flow Diagram\u003c\/span\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003cp bis_size='{\"x\":12,\"y\":289,\"w\":576,\"h\":0,\"abs_x\":428,\"abs_y\":551}'\u003e\u003c!-- wp:paragraph --\u003e\u003c\/p\u003e\n\u003cp bis_size='{\"x\":12,\"y\":289,\"w\":576,\"h\":19,\"abs_x\":428,\"abs_y\":551}'\u003e\u003ca href=\"\/blogs\/newsletters\/eyeonvision-august-2021-blind-cricket\"\u003eClick Here for BRVT Development History \u0026amp; Applications\u003c\/a\u003e\u003c\/p\u003e\n\u003cp bis_size='{\"x\":12,\"y\":324,\"w\":576,\"h\":0,\"abs_x\":428,\"abs_y\":586}'\u003e\u003c!-- \/wp:paragraph --\u003e\u003c\/p\u003e","brand":"Precision Vision","offers":[{"title":"Default Title","offer_id":45921488076961,"sku":"4500","price":185.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0718\/4321\/7569\/files\/4500-Web.jpg?v=1776157164","url":"https:\/\/precision-vision.com\/products\/brvt-the-berkeley-rudimentary-vision-test","provider":"Precision Vision","version":"1.0","type":"link"}
