Mugihe uhisemo indorerwamo zizuba kugirango urinde amaso yawe, ingingo zikurikira zigomba gutekerezwa:

1. Kurinda UV

• Ikirango cya UV400: Reba indorerwamo zizuba zanditseho "UV400". Ibi byerekana ko lens ishobora guhagarika 99% cyangwa irenga imirasire ya ultraviolet ifite uburebure bwa metero 400, harimo UVA (315 - 400 nm) na UVB (280 - 315 nm). Imirasire ya Ultraviolet irashobora kwangiza amaso, nka cataracte, Photokeratitis, no kwangiza conjunctiva na cornea. Indorerwamo zizuba zidafite uburinzi buhagije bwa UV zirashobora gutuma abanyeshuri baguka munsi yumwijima - ibara ryamabara, bigatuma imirasire myinshi ya UV yinjira mumaso, bikongera ibyago byo kwangirika.

2. Kugaragara kwumucyo ugaragara

• Gukwirakwiza urumuri rukwiye: Ibikorwa bitandukanye bisaba urwego rutandukanye rwohereza urumuri. Kumikoreshereze rusange yo hanze, lens ifite itumanaho rya 15% - 40% birakwiye. Kurugero, niba utwaye, lens hamwe nogukwirakwiza hafi 18% - 32% nibyiza kuko birashobora kugabanya neza urumuri mugihe bikwemerera kubona neza ibimenyetso byumuhanda, imiterere yumuhanda, nibindi bisobanuro. Lens yijimye cyane irashobora kugabanya kugaragara, cyane cyane mubihe bito - urumuri cyangwa nijoro, bikaba ari bibi cyane.
• Ibara ry'inzira:
  • Icyatsi kibisi: Icyatsi kibisi gikurura urumuri rugaragara neza. Zigumana imyumvire karemano, ituma ibera mubikorwa bitandukanye, cyane cyane gutwara, kuko byerekana neza amabara, aringirakamaro mugutandukanya ibimenyetso byumuhanda.
  • Ibara ry'umukara: Ibara ry'umukara ntiribuza gusa urumuri rwinshi rw'ubururu ahubwo runatanga imyumvire myiza. Bongera itandukaniro, bigatuma bakora cyane mubikorwa nko kuroba, kuko bishobora gufasha gutandukanya ubuso bwamazi nibintu byamazi.
  • Ibara ry'umuhondo: Lens yumuhondo ninziza mukuzamura itandukaniro mubihe bito - urumuri cyangwa ibicu. Bakunze gukoreshwa mu gusiganwa ku maguru cyangwa kurasa, kuko bishobora gutuma ibintu bigaragara neza inyuma yinyuma. Nyamara, ntibikwiriye kumurika izuba ryinshi kuko bidahagarika urumuri rugaragara.

3. Kuba polarisiyasi

• Mugabanye urumuri: Amadarubindi yizuba yizuba afite akamaro kanini mukugabanya urumuri rugaragara hejuru yamazi nkamazi, shelegi, hamwe nudusanduku twimodoka. Kumurika birashobora gutera ikibazo kandi bikagabanya kugaragara neza. Iyo urumuri rugaragaje kuri ubu buso, ruhinduka polarize itambitse. Lens ya polarize ifite filteri idasanzwe ihagarika urumuri rutambitse, bityo bigabanya urumuri. Ibi ni ingirakamaro cyane cyane mubikorwa nkubwato, kuroba, no gutwara, kuko bitezimbere kandi bikagabanya amaso.

4. Ubwiza bwa Lens

• Byumvikane neza: Indanganturo nziza - zifite ubuziranenge zigomba kugira neza neza. Reba kugoreka ikintu icyo ari cyo cyose, guhuzagurika, cyangwa kurigita urebeye mumurongo ugororotse, nk'uruhande rw'umuryango cyangwa ikadirishya. Hindura ibirahuri hirya no hino ureba umurongo; niba umurongo ugaragara nkuwunamye cyangwa uhindagurika, ubuziranenge bwa lens ni bubi.
• Shushanya - kurwanya: Kubera ko amadarubindi yizuba akoreshwa hanze, lens ikunda gushushanya. Lens hamwe nigishushanyo - igipfundikizo gishobora kwihanganira igihe cyacyo. Ibikoresho bikomeye - bipfundikijwe bya pulasitiki cyangwa ibirahuri birasa cyane - birwanya ugereranije na plastiki isanzwe.

5. Ikadiri ikwiye

• Humura: Ikadiri igomba guhuza neza mumaso yawe idateye ingingo zumuvuduko kumazuru cyangwa mumatwi. Gerageza kumurongo itandukanye kugirango ubone ingano nuburyo bukwiye mumaso yawe. Urusengero rugomba kwicara neza ariko ntirukomere cyane kuruhande rwumutwe wawe, kandi amazuru agomba gushyigikira uburemere bwibirahuri ku zuru.
• Igipfukisho: Ikadiri igomba gutanga ubwishingizi buhagije kugirango urinde amaso yawe urumuri rwizuba ruva kumpande. Amakadiri yo gupfunyika ni amahitamo meza kuko ashobora guhagarika urumuri rwinshi rwa peripheri, bikagabanya urugero rwimirasire ya UV hamwe nurumuri rugera mumaso yawe kumpande.
