I-Slab Off ukuze ufumane umfanekiso odityanisiweyo we-anisometropia
Sakhe safumana iiodolo ezifuna i-Slab Off, kwaye sihlala sixhalabile kwiimfuno zabathengi.
Iindaba ezimnandi ukuba sisandula ukufaka ukhetho lwe-Slab Off kwilebhu yethu, ukuxhasa ii-odolo zezigulana xa kukho imfuneko kuyo.
Inyani yeyokuba xa unxibe iilensi eziqhubekayo, kokukhona umntu onxibayo kufuneka ajonge ezantsi kokukhona ziphezulu ezo ziphumo zeprismatic. Kwaye ukuba umntu onxibileyo unamandla angalinganiyo e-lens (anisometropia) amakhulu kuno-1.50D, unokufumana umbono olufifi, ukubona kabini, okanye uziva exinene kakhulu.
Njengoko kubonisiwe kwimifanekiso engezantsi, 2# umfanekiso uxela xa ubona ukwindawo esezantsi imifanekiso esuka kwiilensi ezimbini zamandla ahlukeneyo ziya kwahluka, kwaye umahluko onjalo ubangela imifanekiso engadityaniswanga emehlweni; 3# umfanekiso uxela indlela iprism lens esebenza ngayo; kwaye 4# umfanekiso uxelela umfanekiso odityanisiweyo ufunyenwe xa udibanisa iprism lens.
Ngoko ke ukuba iingxaki zombono oluluzizi okanye umbono kabini zenzeka nge anisometropia, ugqirha wamehlo uzakuseta ilens ngembuyekezo kwisakhelo, njengoko kubonisiwe kwi 3#&4# imifanekiso.
Kwaye isisombululo sethu siyivelisa ngokusila ngokukhululekileyo ukongeza i-Slab Off prism kwiilensi eziqhubekayo. Umgangatho we-Slab ucinyiwe uya kufumaneka kuthabatha olomeleleyo okanye ubuthathaka kunye nelensi.
Siya kuqaphela ukuba i-Slab Off iphumela kwindawo yokugqwesa kunye nebhendi yokungaboni kakuhle, ngokuqhelekileyo phakathi kwe-3-7 mm ngokuxhomekeke kwinqanaba lolawulo kunye nokusebenza esinokufaka isicelo koomatshini.
*Thelekisa umphezulu ongemva we-Slab off lens kunye nelens eqhelekileyo.
*Indawo yeSlab off zone.
Siyathemba ukuba emva kokugqoka i-Slab Off umthengi uya kuphendula ngokuthe ngqo ngobuso obukhululekile okanye ngesivakalisi esithi "Wow, oku kuvakalelwa kakuhle" okanye "Ndandikwazi ukuyifunda ngaphambili kodwa kwakunoxinzelelo. Ngoku kuthe kratya” okanye kwiimeko ezinzima: “Umbono ophindwe kabini umkile! Ekugqibeleni ndinomfanekiso omnye kwakhona.”
Wamkelekile ukuba uqhagamshelane nathi ngolwazi oluthe vetshe.
