Cov tshuaj pleev xim rau niaj hnub nrog kev tiv thaiv UV feem ntau muaj nyob hauv ntau txoj kev:

1. Kos "UV400":

Nws txhais tau hais tias qhov kev sib txuas ntawm lub lens rau ultraviolet lub teeb yog 400 nm, uas yog, nws txoj kab nruab nrab ntawm ib lub suab qis tshaj 400 nm tsis tuaj yeem ua ntau tshaj 2%.

2. Kos "UV" thiab "UV tiv thaiv":

Nws txhais tau hais tias lub teeb meem wavelength ntawm lub lens rau ultraviolet lub teeb yog 380 nm.

3. Kos "100% UV absorption":

Nws txhais tau hais tias lub lens muaj 100% kev haum ua haujlwm rau ultraviolet rays, uas yog, qhov nruab nrab ntawm kev xa xov hauv ultraviolet ntau yog tsis ntau tshaj 0.5%.

Feem ntau, cov ntawv hais saum toj no tau hu ua looj tsom iav uas tiv thaiv kev tiv thaiv ultraviolet rays.

Mis Deficiency 2:

Polarized looj tsom iav qhov muag zoo dua li lub hnub ci looj tsom iav

Dab tsi yog qhov kev xa tawm? Qhov tsos tsaus tsawv lens, qhov zoo dua?

Kev sib kis, kuj hu ua kev sib kis coefficient, yog qhov sib piv ntawm cov teeb uas sib kis tau los ntawm cov khoom siv los yog nruab nrab los yog qhov nyiaj pab cuam rau qhov teeb meem. Kev xa tawm tsis yog tus neeg sawv cev ntawm qib zoo ntawm cov iav.

Ntau daim iav tsom iav yuav muaj ntau lo lus xws li 0, 1, 2, 3, 4, etc., lub ntsiab lus yog raws li nram no:

1. Tus "0" theem nruab nrab ntawm daim ntawv thov rau hnub ci ntsa iab.

2. Tus "1" rating txhais tau hais tias nws yog haum rau cov huab cua pos huab.

3. Qhov "2" rating siv rau cov huab cua zoo.

4. Qhov "3" rating siv rau huab cua hauv lub hnub.

5. Cov qhab nia "4" siv rau cov daus los yog dej hiav txwv.
