Kwintsimi yee-eyewear, iilensi zidlala indima ebalulekileyo ekuboneleleni ngokucacileyo nangokukhululekileyo. Xa uthetha ngenjongo yelensi, igama elinye elihlala livela ngu-1.499. Kodwa lithetha ukuthini ngokwenene? Iwachaphazela njani amava ethu okubonwayo?
Ukubeka nje, i-1.499 ibhekisela kwisalathiso se-refractive se-lens material. Isalathiso se-refractive simisela ukuba ingakanani i-lens inokugoba njengoko ukukhanya kudlula kuyo, ekugqibeleni kuchaphazela amandla ayo okulungisa iingxaki zombono. Isalathisi esiphezulu se-refractive sithetha ukuba ilensi inokugoba ukukhanya ngokufanelekileyo, okukhokelela kwiilensi ezincinci, ezikhaphukhaphu. Ngakolunye uhlangothi, isalathisi esisezantsi se-refractive sinokufuna iilensi ezityebileyo ukufezekisa umgangatho ofanayo wokulungiswa.
1.499 iilensi, ezifumaneka ngokuqhelekileyo kwiiglasi zamehlo, zinika ibhalansi elungileyo phakathi kobunzima, ubukhulu kunye nokusebenza kwamehlo. Zenziwe ngeplastiki ebizwa ngokuba yi-CR-39, eyaziwayo ngeempawu zayo ezibalaseleyo zamehlo. Ezi lens ziyafumaneka kwiintlobo ngeentlobo zemiyalelo, kubandakanywa ukujonga kufutshane, ukubona kude, kunye ne-astigmatism.
Enye yeenzuzo eziphambili zeelensi ze-1.499 kukufikeleleka kwazo. Ixabiso elincinci kakhulu ukuvelisa kuneelensi ezinezalathisi eziphezulu ze-refractive ezifana ne-1.60 okanye i-1.67. Oku kubenza babe lukhetho oludumileyo lwabantu abafuna isisombululo sempahla yamehlo engabizi kakhulu ngaphandle kokubeka esichengeni kumgangatho wokubonwayo.
Ukongeza, iilensi ze-1.499 zibonelela ngokugqwesileyo kokumelana nempembelelo kunye nokuqina kokunxiba kwansuku zonke. Abafane bafane nemikrwelo kwaye banokumelana neempembelelo zengozi ngcono kunezinye imathiriyeli yelensi. Nangona kunjalo, kubalulekile ukuqaphela ukuba zisenokungabi zincinci okanye zilula njengeelensi zesalathisi eziphezulu. Ukuba unommiselo ophezulu, unokufuna ukujonga iinketho eziphezulu zesalathisi kwinkangeleko elungelelanisiweyo.
Isishwankathelo, injongo yeelensi ze-1.499 kukubonelela abantu ngenketho ethembekileyo nefikelelekayo yokulungisa umbono wabo. Nokuba ubona kufutshane, ubona kude, okanye une-astigmatism, ezi lens zibonelela ngendlela efanelekileyo yokusebenza kunye nexabiso. Ngokuqonda ihlabathi le1.499 iilensi, unokwenza isigqibo esinolwazi xa ukhetha i-eyewear ehambelana neemfuno zakho.
