Valiwe ukuze uthole isithombe esihlanganisiwe se-anisometropia
Sike sathola ama-oda adinga i-Slab Off, futhi sihlala sikhathazekile ngezidingo zamakhasimende.
Izindaba ezinhle ukuthi sisanda kufaka inketho ye-Slab Off elabhorethri yethu, ukusekela ama-oda eziguli uma kunesidingo.
Iqiniso liwukuthi uma ugqoka amalensi aqhubekayo, lapho umuntu ogqokile edinga ukubheka phansi kakhulu, imiphumela ye-prismatic iba mikhulu. Futhi uma umuntu ogqokile enamandla elensi angalingani (i-anisometropia) angaphezu kuka-1.50D, angase abone ngokufiphala, abone kabili, noma azizwe ecindezelekile kakhulu.
Njengoba kuboniswe ezithombeni ezingezansi, isithombe esingu-2# sibonisa ukuthi uma ubheka usuka endaweni ephansi izithombe ezivela kumalensi amabili anamandla ahlukene zizohluka, futhi umehluko onjalo ubangela izithombe ezingahlangani emehlweni; isithombe esingu-3# sibonisa ukuthi ilensi ye-prism isebenza kanjani; kanti isithombe esingu-4# sibonisa ukuthi isithombe esihlanganisiwe sitholakala uma kungezwa ilensi ye-prism.
Ngakho-ke uma kuvela izinkinga zokubona okufiphele noma ukubona okuphindwe kabili nge-anisometropia, udokotela wamehlo uzofaka ilensi enesinxephezelo kufreyimu, njengoba kuboniswe ezithombeni ezingu-3#&4#.
Futhi ikhambi lethu liyikhiqiza ngokugaya okukhululekile ukuze kufakwe i-Slab Off prism kumalensi aqhubekayo. I-Slab off ejwayelekile izotholakala kulensi enamandla kakhulu noma ebuthakathaka.
Sizoqaphela ukuthi i-Slab Off iholela endaweni yokuphambuka kanye nebhendi yokubona okufiphele, ngokuvamile phakathi kuka-3-7 mm kuye ngezinga lokulawula kanye nokusebenza esingakusebenzisa emishinini.
*Qhathanisa ubuso bangemuva be-Slab off lens kanye ne-lens evamile.
*Indawo ye-Slab engaphandle kwendawo.
Sithemba ukuthi ngemva kokugqoka i-Slab Off ikhasimende lizophendula ngqo ngobuso obukhululekile noma ngomusho othi “Wow, lokhu kuzwakala kukuhle” noma “Ngikwazile ukukufunda ngaphambilini kodwa bekungicindezela. Manje sekuyinto efanayo” noma ezimweni ezimbi kakhulu: “Ukubona kabili sekuphelile! Ekugcineni ngithole isithombe esisodwa futhi.”
Siyakwamukela ukuthi usithinte ukuze uthole ulwazi olwengeziwe.
