CR39 Indorerwamo z'izuba

Ibisobanuro bigufi:

Indorerwamo zizuba nubwoko bwibikoresho byo kureba kugirango birinde kwangirika kwamaso yumuntu biterwa nizuba ryinshi.Hamwe nogutezimbere kurwego rwabantu numuco, indorerwamo zizuba zirashobora gukoreshwa nkibikoresho byihariye kubwiza cyangwa muburyo bwihariye.

Mubisanzwe, indorerwamo zizuba zifite ibikoresho bikurikira:

1. Resin lens Ibikoresho bya Lens: Resin ni ibintu byimiti bifite imiterere ya fenolike.Ibiranga: uburemere bworoshye, ubushyuhe bwo hejuru, kurwanya ingaruka zikomeye, kandi birashobora guhagarika imirasire ya ultraviolet.

2. Nylon lens Ibikoresho bya Lens: bikozwe muri nylon, ibiranga: ubuhanga bukomeye cyane, ubwiza bwiza bwa optique, kurwanya ingaruka zikomeye, mubisanzwe bikoreshwa mubintu birinda.

3. Ibikoresho bya karubone ya polyester (PC lens) yibikoresho: bikomeye, ntibyoroshye kumeneka, birwanya ingaruka, ibikoresho byabugenewe byabugenewe kubirahuri bya siporo, igiciro kiri hejuru yicy'akabuto ka acrylic.

4. Lens ya Acrylic (AC lens) lens lens: Ifite ubukana buhebuje, uburemere bworoshye, kureba kure hamwe no kurwanya igihu.

Intangiriro

Abaganga b'amaso baragusaba ko ugomba guhora wambara amadarubindi kugirango urinde amaso yawe;ibi ni ukubera ko ijisho ryacu (lens) ryoroshye cyane kwinjiza imirasire ya ultraviolet, kandi kwangirika kwimirasire ya ultraviolet bifite ibintu bibiri byingenzi biranga:

1.Ingaruka z'imirasire ya ultraviolet izegeranya.Kubera ko urumuri ultraviolet ari urumuri rutagaragara, biragoye ko abantu babimenya neza.

2.Ingaruka z'imirasire ya ultraviolet kumaso ntisubirwaho, ni ukuvuga, bidasubirwaho.Nka: kubaga cataracte birashobora gusimburwa gusa ninzoka zo mu nda.Kwangirika kwigihe kirekire kumaso birashobora kworoha kwangirika kwa cornea na retina, igicu cya lens kugeza igihe cataracte ibaye, bikaviramo kwangirika kumaso.

Kubera ko kwangirika kwimirasire ya ultraviolet kumaso bitagaragara, ntibishobora guhita byunvikana.Niba utambaye ibirahure, ntabwo wumva bitagushimishije cyane.Bisobanura gusa ko amaso yawe atumva neza urumuri rugaragara (nk'urumuri rutangaje, urumuri, n'umucyo ugaragara)., kandi ntishobora kwirinda kwangirika kwa UV.

Ese amadarubindi yijimye yijimye, nibyiza byo guhagarika UV?

Oya, imikorere yinzira yo guhagarika imirasire ya ultraviolet nuko ivurwa nuburyo budasanzwe (wongeyeho ifu ya UV) mugihe cyo gukora, kugirango lens ibashe gukuramo urumuri rwangiza munsi ya 400NM nkimirasire ya ultraviolet mugihe urumuri rwinjiye.Ntaho bihuriye n'uburebure bwa firime.
