AR coating: Mugenzi mwiza cyane kumurongo wo hejuru

Kubireba neza no kugaragara neza, nibyiza ko tugira lens anti-reflive (AR coating) ikoreshwa kumurongo wo hejuru.AR-yashizwemo indangagaciro ndende yohereza 99.5 ku ijana by'urumuri ku jisho kugirango ibone neza.
Kandi kubera ko AR itwikiriye hafi ya lens ikuraho, ituma indangagaciro ndende igaragara nkaho itagaragara, bityo abandi bakabona amaso yawe, ntabwo ari lens.

Itara ry'ubururu

Itara ry'ubururu rifite uburebure bwumuraba nimbaraga kuva kuri 380 nm (ingufu zisumba 500 nm (ingufu nkeya).
Rero, hafi kimwe cya gatatu cyumucyo ugaragara ni itara ry'ubururu

Itara ry'ubururu ryongeye gushyirwa muri aya matsinda (ingufu nyinshi kugeza ingufu nke):
· Itara rya Violet (hafi 380-410 nm)
· Itara ry'ubururu-violet (hafi 410-455 nm)
· Itara ry'ubururu-turquoise (hafi 455-500 nm)

Kubera imbaraga zabo nyinshi, violet nubururu-violet imirasire irashobora kwangiza ijisho.Kubera iyo mpamvu, iyi mirase (380-455 nm) nayo yitwa "urumuri rwubururu rwangiza."

Imirasire yubururu-turquoise kurundi ruhande, ifite imbaraga nke kandi bigaragara ko ifasha gukomeza gusinzira neza.Kubera iyo mpamvu, imirasire (455-500 nm) rimwe na rimwe yitwa "urumuri rwubururu rufite akamaro."

Imirasire itagaragara ya ultraviolet (UV) irambaraye hejuru yingufu zisumba izindi zose (violet) impera yubururu bwubururu bwa UV imirasire ya UV ifite uburebure buke bwumuraba ningufu nyinshi kuruta ingufu zubururu zigaragara.Imirasire ya UV byagaragaye ko yangiza amaso nuruhu.

Ukuntu urumuri rwubururu Kugabanya Lens rushobora gufasha

Itara ryubururu rigabanya lens ryakozwe hifashishijwe pigment yemewe yongewe kumurongo mbere yo gutara.Ibyo bivuze ko urumuri rwubururu rugabanya ibikoresho biri mubice byose bigize lens, ntabwo ari ibara gusa.Ubu buryo bwa patenti butuma urumuri rwubururu rugabanya lens kugirango rwungurure urugero rwinshi rwurumuri rwubururu na UV.

Ingingo z'ingenzi zerekeye urumuri rw'ubururu

1. Itara ry'ubururu riri hose.
2. Imirasire yoroheje ya HEV ituma ikirere gisa n'ubururu.
3. Ijisho ntabwo ari ryiza cyane muguhagarika urumuri rwubururu.
4. Itara ryubururu rishobora kongera ibyago byo kwangirika.
5. Itara ry'ubururu rigira uruhare mu guhuza amaso.
6. Kurinda urumuri rwubururu birashobora kuba ingenzi nyuma yo kubagwa cataracte.
7. Itara ry'ubururu ntabwo ari ribi.
