Amalensi owadingayoizibuko zakhokuzoncika kudokotela wakho wengilazi yamehlo.Ngaphambi kokuthenga izibuko ezintsha, hlela ukuhlolwa kwamehlo nodokotela wakho wamehlo.Bazonquma ukuthi yiluphi uhlobo lokulungiswa kombono oludingayo.
Umbono Owodwa
Amalensi okubona okukodwa awuhlobo olushibhile futhi olujwayeleke kakhulu lwamalensi engilazi yamehlo.Banomkhakha omkhulu wokubona ngoba balungisa kuphela ukubona ebangeni elithile (kungaba kude noma eduze).Lokhu kuyawahlukanisa namalensi ama-multifocal achazwe ngezansi.
Udokotela wakho cishe uzokunikeza amalensi ombono owodwa uma unokukodwa kwalokhu okulandelayo:
Ukubona eduze
Ukubona kude
I-Astigmatism
Ama-Bifocals
Amalensi e-Bifocal ane-multifocal, okusho ukuthi “anamandla” amabili ahlukene kuwo.Lezi zingxenye ezahlukene zelensi ukubona ibanga elilungile kanye nokubona eduze.
Amalensi e-Bifocal amiselwe abantu abanezinkinga eziningi zokubona.
Ama-Trifocals
Amalensi e-Trifocal afana ne-bifocals.Kodwa banamandla engeziwe okulungisa umbono ophakathi nendawo.Isibonelo, ingxenye emaphakathi ingase isetshenziselwe ukubuka isikrini sekhompyutha.
Ukushiyeka okukhulu kwama-bifocals nama-trifocals ukuthi anomugqa ohlukile phakathi kwenkambu yombono ngayinye.Lokhu kwenza izingxenye ze-lens zikhiqize umbono ohluke kakhulu.Abantu abaningi bayakujwayela lokhu futhi abanankinga.Kodwa lokhu kuphazamiseka kuye kwaholela ekuthuthukisweni kwama-lens athuthuke kakhulu, njengama-progressives.
I-Progressives
Amalensi aqhubekayo angolunye uhlobo lwamalensi amaningi.Basebenzela noma ubani odinga ama-bifocal noma ama-trifocal.Amalensi aqhubekayo ahlinzeka ngokulungiswa okufanayo kokubona eduze, okumaphakathi, nebanga.Benza lokhu ngaphandle kwemigqa phakathi kwesigaba ngasinye.
Abantu abaningi bakhetha lawa ma-lens amaningi ngoba uguquko phakathi kwezinkambu zokubona lushelela.
