● Iilensi eziqhubekayo zikwaxhaphakile phakathi kwabantu abafuna ukubona umgama kunye nezilungiso ezikufutshane, njengabo basebenza ngeekhompyutha okanye abafuna ukufunda ixesha elide. Ngeelensi eziqhubela phambili, umntu ozinxibileyo kufuneka nje ahambise amehlo ngokwemvelo, ngaphandle kokuthamba intloko okanye ukulungelelanisa ukuma, ukufumana eyona nto igxile kuyo. Oku kubenza balungele ukusetyenziswa kwemihla ngemihla, njengoko umntu ozinxibileyo enokutshintsha ngokulula ukusuka ekuboneni izinto ezikude ukuya kwizinto ezikufutshane ngaphandle kokutshintshela kwiiglasi ezahlukeneyo okanye iilensi.
● Xa kuthelekiswa neelensi eziqhelekileyo eziqhubekayo (9+4mm/12+4mm/14+2mm/12mm/17mm), iingenelo zoyilo lwethu olutsha oluqhubela phambili zezi:
1. Uyilo lwethu lokugqibela oluthambileyo lunokwenza utshintsho lwe-astigmatism ngokutyibilikayo kwindawo eyimfama ukunciphisa ukungonwabi kokunxiba;
2. Sazisa uyilo lwe-aspheric kwindawo esetyenziswa kakhulu ukubuyisela kunye nokwandisa amandla ogxininiso lwe-peripheral, okwenza umbono kwindawo yokusetyenziswa okude ucace ngakumbi.
