Kuki indorerwamo zizuba zirinda amaso?

Ingaruka z'imirasire ya ultraviolet

Hariho ubwoko butatu bwimirasire ya ultraviolet mumirasire yizuba: UVA, UVB, na UVC. Ubusanzwe UVC yakirwa nikirere cyisi, mugihe UVA na UVB byerekanwa nubutaka. Kumara igihe kinini kuri iyi mirasire ya ultraviolet birashobora kwangiza amaso atandukanye, harimo:

1. Photokeratitis:

Ubu ni ugutwika hejuru yijisho ryatewe na UVB, bisa no gutwika izuba kuruhu.

2. Cataract:

Kumara igihe kinini imirasire ya ultraviolet byongera ubwonko bwa cataracte kandi bigatera kutabona neza.

3. Kwangirika kwa Macular:

UVA na UVB byihutisha kwangirika kwagace ka macular kandi bigira ingaruka zikomeye kumyerekezo yo hagati.

4. Pterygium:

Uku gukura kuri cornea iterwa ahanini no gukurura ultraviolet kandi birashobora gusaba ubuvuzi.

Uburyo bwo kurinda amadarubindi

Indorerwamo nziza yizuba irashobora guhagarika neza 99% kugeza 100% yimirasire ya UVA na UVB, bityo bikagabanya kwangirika kwizuba ryimirasire yangiza mumaso. Ingaruka zo kurinda indorerwamo zizuba zigaragarira cyane cyane mubice bikurikira:

1. Guhagarika imirasire ya UV:

Indorerwamo yizuba nziza cyane izerekana urwego rwo kurinda UV400, bivuze ko ishobora guhagarika imirasire ya ultraviolet yose hamwe nuburebure bwumurongo uri munsi ya nanometero 400.

2. Kugabanya urumuri:

Lens ya polarize irashobora kugabanya urumuri ruturutse hejuru (nk'amazi, shelegi, nibindi), bigatera ihumure neza kandi neza.

3. Kurinda uruhu ruzengurutse amaso:

Uruhu ruzengurutse amaso ni ruto kandi rwangiritse byoroshye nimirasire ya ultraviolet. Kwambara amadarubindi y'izuba birashobora gutanga ubundi burinzi no kugabanya ibyago byo kurwara kanseri y'uruhu.

4. Irinde umunaniro w'amaso:

Umucyo ukomeye urashobora gutuma ijisho ryijisho ryangirika, kongera umutwaro kumitsi yijisho, kandi bigatera umunaniro wamaso igihe kirekire. Indorerwamo zizuba zirashobora kugabanya ubukana bwurumuri kandi bigatuma amaso aruhuka.

Nigute ushobora guhitamo amadarubindi yizuba

Guhitamo amadarubindi yizuba ntagomba gutekereza kumyambarire yabo gusa, ahubwo tunitondere imikorere yabyo yo kubarinda. Inama zikurikira zirashobora kugufasha guhitamo neza:

1. Reba ikirango cyo kurinda UV:

Menya neza ko indorerwamo zizuba zifite ikirango cya UV400 kirinda imirase yangiza ultraviolet.

2. Hitamo ibara ryiza rya lens:

Icyatsi kibisi kirashobora kugabanya urumuri muri rusange rudahinduye ibara, mugihe ibara ryijimye na amber rishobora kongera itandukaniro nubwenge bwimbitse, bikwiranye na siporo yo hanze.

3. Reba ibikoresho bya lens:

Lens ya polyakarubone yoroheje kandi irwanya ingaruka, ibereye siporo no gukoresha buri munsi.

4. Menya neza ko lens yuzuye:

Ibinini binini hamwe nigishushanyo mbonera gishobora gutanga uburinzi bwiza no gukumira imirasire ya ultraviolet kwinjira kumpande.

Indorerwamo z'izuba ntabwo ari ibikoresho by'imyambarire gusa, ahubwo ni ngombwa no kurinda ubuzima bw'amaso. Hitamo amadarubindi yo mu rwego rwo hejuru kugirango uhe amaso yawe uburinzi bwiza mugihe wishimira izuba.
