Valiwe ukuze ufumane umfanekiso odibeneyo we-anisometropia
Sakha safumana iiodolo ezifuna iSlab Off, kwaye sihlala sixhalabile ngemfuno zabathengi.
Iindaba ezimnandi kukuba sisandula ukufaka iSlab Off kwilebhu yethu, ukuxhasa iiodolo zezigulana xa kukho imfuneko.
Inyani yile yokuba xa unxibe iilensi eziqhubekekayo, kokukhona umntu onxibe iilensi kufuneka ajonge ezantsi, kokukhona ezo ziphumo zeprismatic ziphezulu. Kwaye ukuba umntu onxibe iilensi zinamandla angalinganiyo (i-anisometropia) angaphezu kwe-1.50D, unokuba nombono ofipheleyo, umbono ophindwe kabini, okanye uzive ngathi uxinezelekile kakhulu.
Njengoko kubonisiwe kwimifanekiso engezantsi, umfanekiso we-2# uxela xa ubona usuka kwindawo esezantsi ukuba imifanekiso evela kwiilensi ezimbini zamandla ahlukeneyo iya kwahluka, kwaye loo mahluko ubangela imifanekiso engadibaniyo emehlweni; umfanekiso we-3# uxela indlela esebenza ngayo ilensi yeprism; kwaye umfanekiso we-4# uxela ukuba umfanekiso odityanisiweyo ufezekiswa xa wongeza ilensi yeprism.
Ngoko ke ukuba kukho iingxaki zokubona okufipheleyo okanye ukubona kabini nge-anisometropia, ugqirha wamehlo uza kubeka ilensi enomnyinyiva kwifreyimu, njengoko kubonisiwe kwimifanekiso emi-3 nengama-4.
Kwaye isisombululo sethu kukuyenza ngokuyigaya ngokukhululekileyo ukuze kongezwe i-Slab Off prism kwiilensi eziqhubekekayo. I-Slab off eqhelekileyo iyafumaneka kwilensi enamandla okanye ebuthathaka.
Siza kuqaphela ukuba iSlab Off ibangela indawo egqwethekileyo kunye nebhendi yombono ofipheleyo, ngesiqhelo phakathi kwe-3-7 mm kuxhomekeke kwinqanaba lolawulo kunye nokusebenza esinokukusebenzisa koomatshini.
*Thelekisa umphezulu ongasemva welensi yeSlab off kunye nelensi eqhelekileyo.
*Indawo yeSlab engaphandle kwendawo.
Sinethemba lokuba emva kokunxiba iSlab Off umthengi uza kuphendula ngokuthe ngqo ngobuso obukhululekileyo okanye ngesivakalisi esithi “Wow, oku kuvakala kamnandi” okanye “Ndikwazile ukukufunda ngaphambili kodwa bekuxinezelekile. Ngoku kuthe tye ngakumbi” okanye kwiimeko ezigqithisileyo: “Ukubona kabini akusekho! Ekugqibeleni ndinomfanekiso omnye kwakhona.”
Wamkelekile ukuba unxibelelane nathi ukuze ufumane ulwazi oluthe kratya.
