Ikigeretse kuri ibyo, UV igaragaramo ni kimwe cyangiza, cyongera guhura, kandi cyikuba kabiri ibyago bimwe na bimwe nk'amazi cyangwa shelegi - urugero, amazi agaragaza 100% by'urumuri rwa UV na shelegi bigaragaza 85% by'urumuri rwa UV.

Imirasire ya UV ni iki?

Umucyo ufite uburebure buri munsi ya 400 nm (nanometero) bisobanurwa nkimirasire ya UV kandi bigashyirwa mubwoko butatu cyangwa bande - UVA, UVB na UVC.

• UVC:Uburebure: 100-279 nm. Byuzuye neza na ozone kandi ntagaragaza iterabwoba.
• UVB:Uburebure: 280-314 nm. Gusa igice cyahagaritswe nigice cya ozone kandi gishobora gutwika uruhu namaso bitera ingaruka zigihe gito nigihe kirekire kumaso no kureba.
• UVA:Uburebure: 315-399 nm. Ntabwo yakiriwe na ozone igatera kwangiza cyane ubuzima bwamaso niyerekwa.

Mugihe urumuri rwizuba arirwo soko nyamukuru yimirasire ya UV, amatara yo kumanika nigitanda nabyo ni isoko yimirasire ya UV.

Kuki Amaso Yawe Akeneye Kurinda UV buri munsi?

Bisa n '“izuba ryaka,” ntushobora kubona ububabare cyangwa ibimenyetso kugeza amasaha menshi nyuma yo guhura; icyakora, ibimenyetso birimo gutukura, kumva urumuri, kurira cyane no kumva ufite ijisho. Iyi miterere isanzwe ahantu hirengeye kumurima wa shelegi ugaragara cyane kandi byitwa urubura. Kubwamahirwe, nkizuba ryinshi, mubisanzwe nigihe gito kandi iyerekwa risubira mubisanzwe nta byangiritse bihoraho.

Kumara igihe kinini kumirasire ya UV birashobora kwangiza isura yijisho (adnexa) hamwe nimiterere yimbere, nka retina, imitsi ikungahaye kumitsi yijisho rikoreshwa mukubona.
