Kuki Lensike ya Polyakarubone?
Polyakarubone ni ibintu birwanya ingaruka. Yatunganijwe mu myaka ya za 70 kugirango ikoreshwe mu kirere harimo ingofero y’ingofero y’indege hamwe n’ikirahuri cy’ibirahure, niba rero ntakindi, nibyiza cyane…
Mu myaka ya za 1980 polyakarubone yakoreshwaga mu ndimi kuko yari yoroshye, yoroshye kandi irwanya ingaruka kurusha ikirahure. Muri iki gihe, ni igipimo cy’amadarubindi y’umutekano, ibirahuri by’abana hamwe n’amadarubindi ya siporo, bitewe n’ingaruka nziza zo guhangana.
Polyakarubone ni thermoplastique itangira inzira yo gukora lens nka pellet zakozwe muburyo bwitwa inshinge. Muri iki gihe, pellet zirahagarikwa munsi yumuvuduko mwinshi muburyo bwa lens, hanyuma bikonjeshwa kugirango bibe lensike ikomeye.
Kimwe no gukomera kwayo, lensike ya polyakarubone isanzwe ibuza 100% imirasire yizuba ya UV idakeneye igifuniko, bivuze ko amaso yawe arinzwe neza. Izi lens kandi zitangwa muburyo bwagutse bwo guhitamo (nka lens igenda itera imbere) kuruta ibindi bikoresho byingirakamaro.
Mugihe polyakarubone idashidikanywaho itera ingaruka zidashobora kwihanganira, biramba biza kubiciro. Polyakarubone ifite lens igaragara cyane kuruta plastiki cyangwa ikirahure, bivuze ko igipfunsi kirwanya anti-reaction gishobora gukenerwa. Kuruhande rwiyi polyakarubone ifite Abbe agaciro ka 30 gusa, bivuze ko itanga ubuziranenge bwiza bwa optique kumahitamo yavuzwe mbere.
Lens Kuri Presbyopiya - Iterambere
Niba urengeje imyaka 40 kandi ukaba ufite ikibazo cyo kubona hafi yawe kandi ukagera, birashoboka ko uhura na presbyopiya. Lens igenda itera imbere nigisubizo cyiza kuri presbyopia, iguha icyerekezo gikaze intera iyo ari yo yose.
Ni izihe nyungu za Lens Iterambere?
Kimwe na bifocal lens, intambwe igenda itera intambwe ifasha uyikoresha kubona neza intera itandukanye ikoresheje lens imwe.
