Iilensi ozifunayoiindondo zakhokuya kuxhomekeka kumyalelo wakho weglasi yamehlo.Ngaphambi kokuba uthenge iiglasi ezintsha, cwangcisa uvavanyo lwamehlo kunye nogqirha wakho wamehlo.Baya kugqiba ukuba luhlobo luni lolungiso lombono olufunayo.
Umbono omnye
Iilensi zombono omnye lolona didi lusezantsi noluqhelekileyo lweelensi zeglasi.Banendawo enkulu yombono kuba balungisa kuphela umbono kumgama othile (nokuba kude okanye kufutshane).Oku kwahlula kwiilensi ezininzi ezichazwe ngezantsi.
Ugqirha wakho uya kukunika iilensi zombono omnye ukuba unenye yezi zilandelayo:
Ukubona izinto ezikufutshane
Ukubona kude
I-Astigmatism
Bifocals
Iilensi ze-Bifocal zi-multifocal, oku kuthetha ukuba "zinamandla" amabini ahlukeneyo kuzo.La macandelo ahlukeneyo elensi achanekileyo ukubona umgama kunye nombono okufutshane.
Iilensi ze-Bifocal zimiselwe abantu abaneengxaki ezininzi zombono.
Ii-Trifocals
Iilensi ze-Trifocal zifana nee-bifocals.Kodwa banamandla ongezelelweyo okulungisa umbono ophakathi.Umzekelo, indawo ephakathi ingasetyenziselwa ukujonga isikrini sekhompyuter.
Intsilelo ephambili ye-bifocals kunye ne-trifocals kukuba banomgca ocacileyo phakathi kwendawo nganye yombono.Oku kwenza ukuba amacandelo e-lens avelise umbono ohluke kakhulu.Abantu abaninzi bayayiqhela le nto kwaye abanangxaki.Kodwa le ntsilelo iye yakhokelela ekuphuhliseni iilensi eziphambili ngakumbi, ezifana nenkqubela phambili.
Abaqhubela phambili
Iilensi eziqhubekayo zolunye uhlobo lwelensi ye-multifocal.Basebenzela nabani na ofuna i-bifocals okanye i-trifocals.Iilensi eziqhubekayo zibonelela ngolungiso olufanayo kumbono okufutshane, ophakathi, kunye nomgama.Benza oku ngaphandle kwemigca phakathi kwecandelo ngalinye.
Abantu abaninzi bakhetha ezi lens ezininzi kuba inguqu phakathi kwemimandla yombono igudileyo.
