Kwinqanaba elifanayo, isalathisi esiphezulu se-refractive, i-lens encinci. Isalathiso se-refractive ye-1.50 okanye i-1.56 ifanelekile ekukhethweni ngaphakathi kwee-degrees ezingama-300, i-refractive index ye-1.56 okanye i-1.60 ifanelekile ukukhethwa phakathi kwe-300 kunye ne-500 degrees, i-refractive index ye-1.67 ifanelekile ekukhethweni phakathi kwe-500 kunye ne-800 degrees, kunye ne-refractive. isalathisi se-1.70 kunye ne-1.74 ifanelekile ukukhetha ngaphezu kwe-800 degrees.
Njengoko sonke siyazi, inzuzo enkulu ye-1.50 ye-refractive index kukuba inenombolo ephezulu ye-Abbe ye-58, ilandelwa yixabiso elifikelelekayo, elilungele ngokukodwa abantu abane-myopia ephantsi.
Intshayelelo yeMveliso
Umntwana ukhetha i-lens nge-index refractive ye-1.50. Ukuba umntwana wakho uneengxaki ezibonakalayo, akufanelekanga ukugqoka iilensi zokukhusela kunye nokulawula, okanye uhlahlo lwabiwo-mali aluvumeli ukusetyenziswa kweelensi zokuthintela kunye nokulawula. Emva koko iilensi eziqhelekileyo zezona zifanelekileyo kubantwana (i-myopia engaphantsi kwama-400 degrees). Yilensi yesalathisi se-1.50.
1. Inombolo ye-Abbe ephezulu: inciphisa umphumo wokusasazeka ekucaciseni. Ngokukodwa kubantwana ababona kude, apho ubukhulu beziko bukhulu, inani le-Abbe libaluleke kakhulu. (Iliso lomntu linenombolo ye-Abbe ye-58.6, ngelixa i-1.50 i-refractive index lens inenombolo ye-Abbe ye-58)
2. Ngexabiso eliphantsi: Abantwana batshintsha iilensi ngokukhawuleza, kwaye kubalulekile ukuba zingabizi.
3. Ubunzima bukwamkelekile: xa kuthelekiswa ne-1.56, ubunzima kunye nobuninzi buphezulu, ukunciphisa impembelelo yokukrala ekucaciseni.
Undoqo kukuba: khulisa inani leeglasi ezinxitywa ngumntwana wakho ezikhangeleka njengeliso lomntu.
