Kev siv cov kab teeb xiav xiav tau dhau los ua ntau yam haujlwm, suav nrog kev tshawb fawb tshawb fawb, txheej txheem kho mob, thiab kev lom zem. Thaum cov lasers no muaj txiaj ntsig ntau, lawv lub peev xwm ua rau qhov muag puas yog qhov kev txhawj xeeb loj.
Nkag siab Blue Laser Beams
Blue lasers feem ntau muaj ib lub wavelength ntawm 400 mus rau 500 nanometers (nm), uas ntog hauv qhov pom spectrum. Vim lawv lub wavelength luv luv thiab lub zog siab, xiav lasers tuaj yeem nkag mus rau lub qhov muag tob dua li lwm cov xim, ua rau muaj kev pheej hmoo ntau dua rau cov ntaub so ntswg retinal. Qhov kev siv thiab lub sij hawm ntawm kev raug rau lub teeb laser yog qhov tseem ceeb hauv kev txiav txim siab qhov muag puas.
Mechanisms ntawm qhov muag puas los ntawm Blue Laser Beams
Blue laser beams tuaj yeem ua rau ob qho tib si photochemical thiab thermal puas rau ob lub qhov muag. Photochemical kev puas tsuaj tshwm sim thaum lub teeb laser cuam tshuam nrog retina, ua rau cov tshuaj hloov pauv hauv cov cell photoreceptor. Cov kev hloov no tuaj yeem ua rau cell tuag thiab tsis pom kev tom qab. Kev puas tsuaj cua sov, ntawm qhov tod tes, tshwm sim los ntawm kev nqus ntawm lub zog laser los ntawm cov ntaub so ntswg, ua rau cov ntaub so ntswg cua sov thiab muaj peev xwm hlawv.
Lub retina yog qhov yooj yim tshaj plaws ntawm lub qhov muag thaum raug cov kab teeb xiav laser. Cov photons muaj zog heev tuaj yeem nkag mus rau lub cornea thiab lens, tsom ncaj qha rau ntawm retina. Qhov kev mob siab rau lub zog no tuaj yeem ua rau muaj kev puas tsuaj hauv cheeb tsam, xws li kub hnyiab lossis kua muag hauv retina. Nyob ntawm qhov hnyav thiab qhov chaw ntawm qhov raug mob, nws tuaj yeem ua rau tsis pom kev mus tas li lossis txawm tias qhov muag tsis pom.
Cov tsos mob ntawm Laser Qhov muag raug mob
Cov tsos mob ntawm laser qhov muag raug mob tuaj yeem sib txawv nyob ntawm qhov hnyav thiab qhov chaw ntawm qhov kev puas tsuaj. Cov tsos mob muaj xws li qhov muag tsis pom kev, flashes ntawm lub teeb, floaters, mob, thiab liab. Nyob rau hauv cov xwm txheej hnyav, cov tib neeg tuaj yeem pom qhov tsis pom kev loj lossis qhov muag tsis pom. Yog tias ib qho ntawm cov tsos mob no tshwm sim, nws tseem ceeb heev kom nrhiav kev kho mob tam sim ntawd.
Tiv thaiv Blue Laser Beam puas
Txhawm rau tiv thaiv xiav laser beam puas, ntau yam kev ntsuas tuaj yeem ua:
1. Kev Tiv Thaiv Qhov Muag
Hnav kom haumlaser kev ruaj ntseg eyewearyog txoj hauv kev zoo tshaj plaws los tiv thaiv koj ob lub qhov muag ntawm cov kab teeb laser.Laser tsom iav kev nyab xeeblossis tsom iav yuav tsum hnav thaum twg ua haujlwm nrog lossis nyob ib puag ncig lasers. Xyuas kom meej tias cov looj tsom iav uas koj xaiv tau ntawv pov thawj rau hom laser tshwj xeeb uas koj yuav siv thiab nws ua tau raws li cov qauv kev nyab xeeb tsim nyog.
2. Kev deb thiab kev tiv thaiv
Kev tswj kom muaj kev nyab xeeb nyob deb ntawm qhov chaw laser thiab siv cov teeb meem lossis cov ntaub thaiv npog tuaj yeem txo qhov kev pheej hmoo ntawm qhov muag puas. Tso koj tus kheej kom koj tsis txhob ntsia ncaj qha ntawm lub laser beam, thiab siv lub cev muaj zog los thaiv lub laser beam kom ncav cuag koj ob lub qhov muag lossis lwm tus.
3. Kev cob qhia thiab kev kawm
Kev cob qhia kom raug thiab kev kawm yog qhov tseem ceeb rau kev nkag siab txog cov kev pheej hmoo cuam tshuam nrog cov kab teeb xiav laser thiab paub yuav ua li cas los tswj lawv kom nyab xeeb. Xyuas kom tseeb tias koj tau txais kev cob qhia dav raulaser kev nyab xeebcov txheej txheem, suav nrog cov txheej txheem tuav kom raug, txheej txheem xwm txheej ceev, thiab siv cov cuab yeej tiv thaiv.
4.Labeling thiab ceeb toom
Daim ntawv lo kom raug thiab cov cim ceeb toom yog qhov tseem ceeb rau kev ceeb toom rau tib neeg txog qhov muaj cov lasers thiab tej zaum yuav muaj kev phom sij. Kom meej meej sau tag nrho cov khoom siv laser nrog cov lus ceeb toom qhia txog hom laser, nws lub zog, thiab ib qho tshwj xeebkev ceev faj txog kev nyab xeebuas yuav tsum tau noj. Tsis tas li ntawd, tshaj tawm cov cim ceeb toom hauv thaj chaw uas siv lasers los yog khaws cia kom ceeb toom rau tib neeg txog kev phom sij.
Xaus
Blue laser beams muaj ntau yam txiaj ntsig, tab sis lawv lub peev xwm ua rau lub qhov muag puas tuaj yeem tsis quav ntsej. Los ntawm kev nkag siab txog qhov txaus ntshai thiab siv cov kev tiv thaiv zoo, peb tuaj yeem txaus siab rau qhov zoo ntawm xiav lasers yam xyuam xim. Ib txwm ua qhov tseem ceeb ntawm qhov muag kev nyab xeeb, hnav cov looj tsom iav kom pom kev nyab xeeb ntawm laser, tswj kev nyab xeeb ntawm qhov chaw laser, thiab nrhiav kev cob qhia thiab kev kawm tsis tu ncua. Yog tias koj lossis lwm tus neeg tau ntsib cov tsos mob ntawm qhov muag laser, nrhiav kev kho mob tam sim ntawd kom txo tau qhov kev puas tsuaj thiab khaws koj lub zeem muag.
