Blue Light yog dab tsi?

Lub hnub ci muaj xim liab, txiv kab ntxwv, daj, ntsuab thiab xiav lub teeb ci thiab ntau qhov ntxoov ntxoo ntawm txhua cov xim, nyob ntawm seb lub zog thiab lub zog ntawm tus kheej rays (tseem hu ua hluav taws xob hluav taws xob). Ua ke, qhov spectrum ntawm cov xim dawb rays tsim qhov peb hu ua "dawb lub teeb" lossis hnub ci.

Yog tsis tau nkag mus rau hauv cov physics nyuaj, muaj kev sib cuam tshuam ntawm lub wavelength ntawm lub teeb rays thiab tus nqi ntawm lub zog uas lawv muaj. Lub teeb rays uas muaj qhov ntev wavelengths muaj tsawg zog, thiab cov uas muaj luv wavelengths muaj ntau zog.

Rays ntawm qhov kawg liab ntawm qhov pom lub teeb pom kev muaj qhov ntev wavelengths thiab, yog li ntawd, tsawg zog. Rays ntawm xiav kawg ntawm lub spectrum muaj luv wavelengths thiab ntau zog.

Cov hluav taws xob hluav taws xob tsuas yog dhau ntawm qhov kawg liab ntawm qhov pom lub teeb pom kev yog hu ua infrared - lawv ua kom sov, tab sis pom tsis tau. (Lub "cov teeb sov sov" koj pom ua kom cov zaub mov sov ntawm koj lub tsev noj mov hauv zos emit infrared radiation. Tab sis cov teeb no kuj emit pom lub teeb liab kom tib neeg paub tias lawv nyob! Tib yam muaj tseeb rau lwm hom teeb hluav taws xob.)

Ntawm qhov kawg ntawm qhov pom lub teeb pom kev zoo, lub teeb xiav xiav nrog qhov luv tshaj plaws wavelengths (thiab lub zog siab tshaj) qee zaum hu ua xiav-violet lossis violet lub teeb. Qhov no yog vim li cas cov hluav taws xob tsis pom hluav taws xob tsuas yog dhau qhov pom lub teeb pom kev zoo hu ua ultraviolet (UV) hluav taws xob.

Cov Ntsiab Lus Tseem Ceeb Txog Lub Teeb Liab

1. Lub teeb xiav nyob txhua qhov chaw.
2. HEV teeb rays ua rau lub ntuj saib xiav.
3. Lub qhov muag tsis zoo ntawm kev thaiv lub teeb xiav.
4. Kev raug xiav lub teeb yuav ua rau muaj kev pheej hmoo ntawm macular degeneration.
5. Lub teeb xiav ua rau lub qhov muag digital.
6. Kev tiv thaiv lub teeb xiav yuav tseem ceeb dua tom qab phais mob cataract.
7. Tsis yog txhua lub teeb xiav tsis zoo.

Yuav ua li cas Blue Light Txo Lenses tuaj yeem pab tau

Lub teeb xiav txo cov lo ntsiab muag yog tsim los siv cov xim patented uas ntxiv ncaj qha rau lub lens ua ntej txheej txheem casting. Qhov ntawd txhais tau hais tias lub teeb xiav txo cov khoom siv yog ib feem ntawm tag nrho cov khoom siv lens, tsis yog xim lossis txheej. Cov txheej txheem patented no tso cai rau lub teeb xiav txo cov lo ntsiab muag los lim ntau dua ntawm ob lub teeb xiav thiab UV teeb.
