Qhov no tsis yog ib daim ntawv teev npe ntawm daim ntawv thov lo ntsiab muag. Cov kws tshawb fawb kuj tau tsim ib qho khoom siv kho qhov muag uas tuaj yeem ua haujlwm nrog scalpel, ua tsaug rau qhov ntsuas ntsuas peb tuaj yeem tsim cov duab ntawm lub vijtsam, thiab lub periscope tau tsim los rau kev soj ntsuam los ntawm cov chaw nyob.

iav yog lub ntsiab ntawm lo ntsiab muag

Tab sis tej zaum qhov kev siv lo ntsiab muag nrov tshaj plaws yog nyob rau hauv tsom iav. Kho qhov muag tsom iav kom pom tseeb, ua kom nws cov ntse. Yog li ntawd, ua ntej yuav ib khub ntawm cov iav lo ntsiab muag, nws tsim nyog mus ntsib kws kho mob rau cov lus qhia tshaj lij ntawm cov diopters koj xav tau. Txawm hais tias koj tau ua ib qho kev kawm hauv computer, thiab raws li nws cov txiaj ntsig, koj muaj lub tswv yim ntxhib ntawm yam khoom siv kho qhov muag uas koj xav tau, koj yuav tsum tsis txhob yuav lawv yam tsis tau sab laj nrog kws kho qhov muag. Tom qab tag nrho, tus kws kho mob tuaj yeem qhia cov tsom iav nrog rau lwm qhov kev ntsuas qhov muag.lens hwj chim los txhawb koj ob lub qhov muag. Nws kuj tsis pom zoo kom yuav cov iav hauv qhov chaw tsis sib xws - hauv khw lossis khw muag khoom. Yog tias koj hnav tsom iav nrog "tsis ncaj ncees lawm" lo ntsiab muag, cov txheej txheem ntawm kev hloov ntawm lub qhov muag pib, thaum lub cev them nyiaj rau qhov cuam tshuam ntawm cov tsom iav nrog qhov muag qaug zog, mob taub hau thiab tsis pom kev ntxiv.

Goggles

Muaj cov cuab yeej tshwj xeeb uas tsim los txwv cov retina los ntawm kev cuam tshuam sab nraud, piv txwv li, tsom iav rau kev ua haujlwm ntawm khoos phis tawj lossis tsom iav tsav tsheb. Tab sis cov no tsis yog cov khoom siv kho qhov muag, vim tias lawv cov iav muaj cov txheej tshwj xeeb uas hloov cov duab. Qee lub sij hawm cov neeg uas muaj kev tsis pom kev tuaj yeem xaj tsom iav kev nyab xeeb nrog lub qhov muag qhov muag - cov khoom siv no yuav tsis tsuas yog qhov pom kev zoo xwb, tab sis kuj saib xyuas lawv cov kev tiv thaiv.

Qhov kev tsim kho qhov muag tshiab kawg

Kev tshawb fawb tau nce mus deb, thiab xyoo 2010, Asmeskas cov kws tshawb fawb tau tsim ib txoj hauv kev los tiv thaiv qhov muag tsis pom kev hauv cov neeg laus - ib qho khoom siv kho qhov muag uas tau tsim ncaj qha rau hauv lub retina. Lub koob yees duab me me no them nyiaj rau thaj chaw puas ntawm lub qhov muag, thaum lub qhov muag noj qab haus huv tseem ua lub luag haujlwm rau peripheral tsis pom kev. Lub hlwb muab cov ntaub ntawv uas tau txais rau hauv ib daim duab - thiab tus neeg pom daim duab tag nrho.

Txawm tias thaum pib ntawm lub xyoo pua 17th, Galileo tau tsim cov khoom siv kho qhov muag uas yooj yim tshaj plaws - lub iav tsom iav, ua tsaug rau qhov nws twb ua tau los soj ntsuam.kev ua ntawm microorganisms. Txij thaum ntawd los, tau kawg, qhov kho qhov muag tsom iav tau dhau los hloov pauv tseem ceeb, thiab niaj hnub no nws twb muaj ob lub astigmatic lo ntsiab muag, uas tsis cuam tshuam cov duab nrog lub teeb pom kev zoo, tab sis muab lub hom phiaj duab. Thiab lub tshuab ntsuas niaj hnub txuas nrog lub khoos phis tawj siv USB txuas, ua tsaug uas nws yuav luag tsis zoo li qhov kev tsim tawm ntawm Italian ci ntsa iab, tab sis muaj tib txoj cai ntawm kev ua haujlwm.

Cov cuab yeej kho qhov muag tau tsim los ua kom lub neej niaj hnub yooj yim rau cov tib neeg, kom pab lawv pom qhov tib neeg lub qhov muag tsis pom ib txwm pom.
