Qhov teeb meem kev nyab xeeb loj tshaj plaws nrog lasers yog qhov muaj peev xwm ua rau tib neeg lub qhov muag thiab tawv nqaij.
Lasers emit ib tug concentrated beam ntawm lub teeb uas yuav ua rau kev puas tsuaj rau lub qhov muag retina thiab daim tawv nqaij yog hais tias tsis muaj kev ceev faj txog kev nyab xeeb. Qhov no yog vim li cas nws tseem ceeb heev uas yuav tsum tau siv cov looj tsom iav tiv thaiv laser thiab ua raws li cov chaw tsim khoom cov lus qhia thaum ua haujlwm lasers.
Tsis tas li ntawd, lasers tuaj yeem ua rau hluav taws kub lossis tawg yog tias siv tsis raug, ua rau nws tseem ceeb rau kev saib xyuas lawv.
Ntev npaum li kev ntsuas kev nyab xeeb, txawm li cas los xij, lasers tuaj yeem yog ib qho kev nyab xeeb thiab muaj txiaj ntsig zoo rau ntau yam kev siv hauv kev lag luam xws li tshuaj, kev tsim khoom, thiab kev tshawb fawb.
