Okwangoku, ii-lens zokudibanisa azikho kuphela izixhobo ezibalulekileyo zokulungisa iziphoso ezingabonakaliyo (ukujonga kwangaphambili, njenge-astigmatism ), kodwa kwakhona kukuvumela ukuba utshintshe umfanekiso wakho, fumana umbala weso.
Iilensi ezidibeneyo eziluhlaza okwesibhakabhaka kwamehlo emnyama
Tshintsha umbala wamehlo alula kunye neelensi zokudibanisa kulula, kodwa ukutshintsha umbala obomdaka obusibhakabhaka kunengxaki. Iilensi ezitshintsha umbala wamehlo zihlukaniswe zibe ngumbala kunye neetoni:
Iilensi ezicatshulwa zivumela ukuba utshintshe umbala wamehlo aphilileyo kuphela, kwaye ngokuqhelekileyo uyenzelwe ukwenza kube lula kwaye kuzaliswe. Ukuba ubeka iilensi eziluhlaza kumaso akho aluhlaza, umbala wabo uzakutshintsha, kwaye umthunzi ongaqhelekanga ungabonakala.

Iilensi eziluhlaza zikhangeleka njani amehlo amaninzi?
Ukufezekisa ukuba ii-lens ezihlaza okwemvelo zikhangele amehlo omdaka, kunzima kakhulu:
- Ubumnyama amehlo, ngakumbi umthunzi we-lens ufunwa ukufihla umbala wokuqala.
- Ububanzi be-lens kufuneka bufanise ububanzi be-iris okanye buyifake, ngaphandle koko umdaka omnyama uza kubonakala ngaphandle.
- Ekubeni iilensi ezinemibala ziphantse i-opaque (ngaphandle kwendawo yomfundi), zifihla ngokupheleleyo iris, ngoko nje iilensi eziluhlaza okwesibhakabhaka kwamehlo ezimdaka zibukeka zingekho ngokwemvelo. Ukubhinqa kuyinqweneleka ukukhetha iilensi kunye neprothem elandelelanayo nomzekelo wendalo we-iris. Iilensi ezinjalo zibiza kakhulu, kodwa zikhangeleka zendalo.

- I-Аcuvue imibala emi-2.
Nangona iilensi zamanqaku ezinamhlanje zincinci ngokwaneleyo, zisasaza i-oksijeni ibe yimbi ngakumbi, engakhokelela ekuveleleni okungathandekiyo. Ngoko ke, xa ugqoke i-lens nawe kunconywa ukuba ube namaconsi akhethekileyo - "iinyembezi zokuzenza" - kwaye iilensi ngokwazo ayifuni ukugqoka ixesha elide.
