Uburyo bwo guhitamo indorerwamo zizuba

Mu mpeshyi ishyushye, uhangayikishijwe numucyo utangaje utuma udashobora guhumura amaso yawe?Iyo tujya mu biruhuko hafi yinyanja cyangwa ski mu rubura, twese twumva urumuri rukomeye kandi rutangaje, kandi dukeneye indorerwamo zizuba kugirango turinde ibirahure.Niko naweindorerwamonibyo?

Mugihe tuguze amadarubindi yizuba, dukwiye kureba niba ibara ryikintu rihinduka mugihe dushyizeho ibirahure, niba amatara yumuhanda asobanutse, kandi niba igishushanyo mbonera cyadukwiriye, niba hari umutwe uzunguruka nyuma yo kwambara, hanyuma tugahagarara kwambara ako kanya niba hari ibitagenda neza.Mubisanzwe, indorerwamo zizuba zisanzwe zifite ubushobozi bwo guhagarika urumuri rukomeye no gushungura imirasire ya ultraviolet.Kubantu bafite ibisabwa byo hasi, indorerwamo zizuba zirashobora gukoreshwa.Ariko, abantu bamwe bafite ibisabwa byujuje ubuziranenge bwo kureba bazahitamo ibirahuri bya polarize.

Ibirahuri bifite polarize ni iki?Ukurikije ihame rya polarisiyasi yumucyo, irashobora gukuramo neza no kuyungurura urumuri rutatanye mumirasire, kugirango urumuri rushobore gushyirwa mumashusho agaragara yijisho riva mumurongo wohereza urumuri rwinzira nziza, kugirango umurima wa iyerekwa rirasobanutse kandi karemano, kimwe nihame ryimpumyi, mubisanzwe bituma ibiboneka bisa nkibyoroshye kandi ntibitangaje..Amadarubindi y'izubabigira ingaruka zimirasire irwanya ultraviolet, ishobora gutandukanya neza imirasire yizuba yizuba.

Igice cya mbere ni polarisiyoneri, ikurura neza urumuri rwerekanwe perpendicular kumurongo wohereza urumuri.Igice cya kabiri n'icya gatatu ni ultraviolet ikurura ibice.Ifasha lensisire ikurura 99% yimirasire ya UV.Kugira ngo lamella itoroshye kwambara.Igice cya kane n'icya gatanu ni ingaruka-zidashobora gukomera.Itanga ubukana bwiza, kurwanya ingaruka, kandi ikingira amaso gukomeretsa.Igice cya gatandatu n'icya karindwi birakomera, kugirango lamellae itoroshye kwambara.Amadarubindi rusange yizuba ku isoko akozwe muri fibre sandwiched polarizing.Iratandukanye nikirahuri cya optique polarized sunlasses, kubera imiterere yacyo yoroshye hamwe na arc idahindagurika, nyuma yinzira ziteranirijwe kumurongo, lens iragoye kubahiriza ibipimo bya optique, kandi ishusho igaragara irekuye kandi ihindagurika.Bitewe no kudahungabana kwa arc no guhindura imikorere yinzira, biganisha ku buryo butagaragara neza bwerekana ishusho itanga urumuri no kugoreka ishusho, idashobora kugera ku ngaruka zisanzwe zo kureba.Kandi hejuru biroroshye gushushanya, kwambara kandi ntibiramba.Kubwibyo, mugihe uguze amadarubindi yizuba, nibyiza kwemeza ko lens ishobora guhagarika neza imirasire irenga 99% ya ultraviolet (harimo na ultraviolet A na ultraviolet B) kandi ikaba ifite ibiranga polarisike kugirango ikureho urumuri (urumuri ruvuga urumuri rukomeye rugaragazwa na inguni zimwe kumaso. bituma bigora kubona ibintu byigihe gito).

Kwangiza imirasire ya ultraviolet kumubiri wumuntu ni byinshi.Igihe kinini cyo kumurika izuba, niko kwangirika kwimirasire ya ultraviolet.Tugomba rero kwambara amadarubindi yizuba kugirango tugabanye imishwarara ya ultraviolet mumaso.

Icyerekezoyibutsa ko mugihe uhisemoindorerwamo, ntutekereze ko lens yijimye, niko imbaraga zo kurwanya ultraviolet zikomeye.Ibinyuranye, ibara ryijimye, niko umunyeshuri azaba mukuru.Hatariho lens anti-ultraviolet zifite umutekano, amaso azahura nimirasire ya ultraviolet, kandi ibyangiritse bizaba bikomeye.Kugira ngo wirinde kwangirika kwamaso yatewe nimirasire ya ultraviolet, birumvikana ko ari ngombwa kugabanya imishwarara yizuba ikomeye cyane cyane hagati ya 10h00 za mugitondo na saa mbiri za mugitondo, iyo izuba rirashe hejuru yisi, nuburemere bwa imirasire ya ultraviolet niyo yo hejuru.Cyane cyane iyo mirase ya ultraviolet igaragarira muri beto, shelegi, inyanja cyangwa amazi niyo ikomeye cyane kandi itera kwangirika cyane kumaso, ariko birengagijwe byoroshye.Kubwibyo, niba ugiye gukora cyane aha hantu umwanya muremure, ibuka kwambara amadarubindi yizuba.
