This test, intended to facilitate the examination of stereoscopic sense in children, is based on two principles: random dots and a grid of parallel cylindrical lenses. The Lang II-R Stereotest represents a development and completion of the previous Lang I-R Stereotest (cat, car, star). This test is also based on the same optical principles for examining binocular vision.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe examination combines random dots and a lens grid and is designed for rapid screening of binocular vision in all age groups, including very young children. The card is presented at a reading distance and the patient is asked what they see while their eye movements are observed.\u003c\/p\u003e\n\u003cp\u003eFour images are presented: elephant, car, crescent moon, and star.\u003cbr\u003eThe elephant, car, and crescent moon are visible only in binocular vision; the star, however, can be seen with one eye and is always visible; it can be perceived in both monocular vision and normal binocular vision, in which case it appears in relief.\u003cbr\u003eSince the star is always visible regardless of stereopsis, if it is not perceived, there are problems other than stereopsis, providing the doctor with additional information that the Lang 1 Test cannot offer.\u003c\/p\u003e\n\u003cp\u003eMany ophthalmologists and orthoptists who use the Lang Stereo Test I-R wish to have another test available, based on the same principle, to avoid the problems resulting from the memorization of figures.\u003c\/p\u003e\n\u003cp\u003eThe star, visible in monocular vision, serves to attract the attention of younger patients, but also provides the satisfaction of recognizing at least one figure even to subjects who do not have stereoscopic vision.\u003c\/p\u003e\n\u003cp\u003eMDR 2017\/745 compliance.\u003c\/p\u003e","brand":"Gima","offers":[{"title":"Default Title","offer_id":49811018056016,"sku":"DG14081","price":350.1,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0866\/3996\/8592\/files\/31314.jpg?v=1740022025","url":"https:\/\/www.cfs.it\/en\/products\/stereotest-lang-ii-r","provider":"CFS Prodotti Medicali s.r.l.","version":"1.0","type":"link"}
