{"product_id":"inverting-spectacles","title":"Inverting Spectacles","description":"Inverting Spectacles Complete with two fully rotating inverting prisms in a shielded spectacle frame. The inverting prisms produce a lateral inversion of the rays – the world thus turns \"upside down\". Besides being a lucid demonstration of the functioning of an inverting prism, experiments involving inverting spectacles encourage a better understanding of the visual process and the functioning of the brain. This also enables a better understanding of the visual perception of babies. Even the apparently simplest things in life (holding and picking up objects, drawing, orientating oneself in a room) become inconceivably difficult.","brand":"3B Scientific","offers":[{"title":"Default Title","offer_id":49419056546069,"sku":"3BS1000895","price":892.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0857\/4897\/3845\/files\/U8476730_01_Inverting-Spectacles.jpg?v=1761021318","url":"https:\/\/unitedsupplycorp.com\/products\/inverting-spectacles","provider":"United Supply Corp.","version":"1.0","type":"link"}
