Indorerwamo z'izuba za CR39

Ibisobanuro bigufi:

Indorerwamo z'izuba ni ubwoko bw'ibikoresho byo kwita ku maso kugira ngo birinde kwangirika kw'amaso y'abantu guterwa n'izuba ryinshi. Bitewe n'uko ibintu by'abantu n'umuco wabo birushijeho kuba byiza, indorerwamo z'izuba zishobora gukoreshwa nk'ibikoresho byihariye by'ubwiza cyangwa imyambarire yabo bwite.

Ubusanzwe, indorerwamo z'izuba zigira ibikoresho bikurikira:

1. Ikirahuri cya resin Ibikoresho bya lens: Resin ni ikintu cya shimi gifite imiterere ya phenolic. Ibiranga: uburemere bworoshye, ubushyuhe bwinshi, ubudahangarwa bukomeye, kandi gishobora gukumira imirasire ya ultraviolet neza.

2. Lensi ya nylon Ibikoresho bya lensi: bikozwe muri nylon, imiterere: ifite ubushobozi bwo guhindagurika cyane, ubwiza bw'amatara bwiza cyane, ihangana bikomeye n'ingaruka, ubusanzwe ikoreshwa nk'ibintu birinda.

3. Indorerwamo za polyester ya kabone (PC lens): zikomeye, ntizoroshye kuvunika, zirinda ingaruka, zigenewe indorerwamo za siporo, igiciro kiri hejuru ugereranyije n'iz'indorerwamo za acrylic.

4. Ibikoresho bya lensi ya acrylic (lensi ya AC): Ifite ubukana bwiza, uburemere bworoshye, ifite icyerekezo cyiza kandi irinda igihu.

Intangiriro y'umusaruro

Abaganga b'amaso bakugira inama yo kwambara indorerwamo z'izuba buri gihe kugira ngo urinde amaso yawe; ibi biterwa nuko imboni y'ijisho ryacu (lens) yoroshye cyane kwakira imirasire ya ultraviolet, kandi kwangirika kw'imirasire ya ultraviolet bifite imiterere ibiri igaragara:

1. Kwangirika kw'imirasire ya ultraviolet kuzagenda kwiyongera. Kubera ko urumuri rwa ultraviolet ari urumuri rutagaragara, biragoye ko abantu barubona mu buryo bw'imitekerereze.

2. Kwangirika kw'imirasire ya ultraviolet ku maso ntabwo gusubirwaho, ni ukuvuga kudasubirwaho. Nk'ibi: kubagwa kwa cataract bishobora gusimburwa gusa n'indorerwamo zo mu maso. Kwangirika kw'igihe kirekire ku jisho bishobora gutuma cornea na retina byangirika byoroshye, bigatuma lens ihinduka igicu kugeza igihe cataract ibaye, bigatuma habaho kwangirika ku buryo buhoraho mu maso.

Kubera ko kwangirika kw'imirasire ya ultraviolet ku maso bitagaragara, ntibishobora guhita byumvikana. Iyo utambaye indorerwamo, ntuba wumva umerewe nabi cyane. Bivuze gusa ko amaso yawe adakunze cyane urumuri rugaragara (nk'urumuri rugaragara, urumuri rugaragara, n'urumuri rugaragara)., kandi ntashobora kwirinda kwangirika kwa UV.

Ese iyo indorerwamo z'izuba zijimye cyane, ni ko ingaruka zo kuziba imirasire ya UV zirushaho kuba nziza?

Oya, akazi ka lens ko kuziba imirasire ya ultraviolet ni uko ivurwa hakoreshejwe uburyo bwihariye (kongeramo ifu ya UV) mu gihe cyo kuyikora, kugira ngo lens ibashe kwinjiza urumuri rwangiza ruri munsi ya 400NM nk'imirasire ya ultraviolet iyo urumuri rwinjiyemo. Ntaho bihuriye n'ubujyakuzimu bwa filime.
