I-Slab Vala ukuze uthole isithombe esihlanganisiwe se-anisometropia
Sake sathola ama-oda adinga i-Slab Off, futhi sihlala siphathelene nezidingo zamakhasimende.
Izindaba ezinhle ukuthi sisanda kufaka inketho ye-Slab Off elebhu yethu, ukuze sisekele ama-oda eziguli uma kunesidingo kuyo.
Iqiniso liwukuthi lapho ugqoke ama-lens aqhubekayo, lapho ogqokile kudingeka abheke phansi nakakhulu leyo miphumela ye-prismatic. Futhi uma ogqokile enamandla angalingani amalensi (anisometropia) amakhulu kuno-1.50D, angase abone ngokufiphele, abone kabili, noma azizwe eshubile kakhulu.
Njengoba kukhonjisiwe ezithombeni ezingezansi, 2# isithombe siyasho ukuthi uma ubona usuka phansi izithombe ezivela kumalensi amabili wamandla ahlukene zizohluka, futhi umehluko onjalo udala izithombe ezingaxutshiwe emehlweni; 3# isithombe sitshela ukuthi i-prism lens isebenza kanjani; futhi 4# isithombe sitshela ukuthi isithombe esihlanganisiwe sifinyelelwa lapho wengeza ilensi yeprism.
Ngakho-ke uma izinkinga zokubona ngokulufifi noma ukubona kabili kwenzeka nge-anisometropia, udokotela wamehlo uzosetha ilensi enesinxephezelo kuhlaka, njengoba kuboniswe kuzithombe ezingu-3#&4#.
Futhi isisombululo sethu siwukukhiqiza ngokugaya kwefomu elikhululekile ukwengeza i-Slab Off prism kumalensi aqhubekayo. I-Slab evamile evaliwe izotholakala ku-minus enamandla noma ilensi ebuthakathaka yokuhlanganisa.
Sizoqaphela ukuthi i-Slab Off iphumela endaweni yokuhlanekezela kanye nebhendi yokungaboni kahle, ngokuvamile phakathi kuka-3-7 mm kuye ngezinga lokulawula nokusebenza esingakusebenzisa emishinini.
*Qhathanisa indawo engemuva ye-Slab off lens namalensi avamile.
*Isikhundla se-Slab off zone.
Sithemba ukuthi ngemva kokugqoka i-Slab Off ikhasimende lizophendula ngokuqondile ngobuso obukhululekile noma ngomusho othi “Wow, lokhu kuzwakala kumnandi” noma “Ngikwazile ukuyifunda ngaphambili kodwa bekucindezela. Manje sekuyalingana” noma ezimweni ezimbi kakhulu: “Ukubona kabili akusekho! Ekugcineni nginesithombe esisodwa futhi.”
Siyakwamukela ukuthi usithinte ukuze uthole imininingwane eyengeziwe.
