Perforated tsom iav, lossis iav nrog qhov, raws li cov tuam ntxhab, yog lub simulator rau kev kho qhov muag. Nws tuaj yeem kho ob qho tib si ze ze thiab pom deb. Cov neeg tsim khoom kuj tau cog lus tias yuav txhim kho qhov pom kev rau astigmatism thiab asthenopia (qhov muag nkees ntev ntev).

Myopia (myopia) tshwm sim hauv ib tus neeg thaum muaj qhov tsis zoo ntawm lub qhov muag, uas lub teeb rays tsom tsis rau ntawm retina, tab sis nyob rau hauv pem hauv ntej ntawm nws. Yog vim li cas rau qhov tshwm sim no yog qhov tsis muaj zog ntawm lub qhov muag cov leeg uas tuav cov kua. Farsightedness yog ib qho tshwm sim uas cov duab ntawm cov khoom yog tsim tom qab retina ntawm lub qhov muag. Feem ntau, cov no yog cov kev hloov ntawm hnub nyoog. Astigmatism yog ib qho kev tsis pom kev tsis pom kev uas qhov pom kev pom tau txo qis nyob deb thiab ze.

Cov tsom iav perforated zoo li looj tsom iav dub thaum xub thawj siab ib muag, tab sis tsis yog lo ntsiab muag, lawv muaj daim hlau nrog lub qhov me me. Cov neeg tsim khoom thov tias qhov no yog kev txhim kho tshiab, tsim los ntawm kev siv cov cai ntawm kev kho qhov muag physics (refraction, defragmentation, cuam tshuam ntawm lub teeb flux). Rau cov neeg uas tsis paub txog physics thiab tshuaj, cov phenomena zoo li mysterious thiab tsis dhaunkag siab. Tab sis tsis muaj leej twg muab delve rau hauv cov ntsiab lus. Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm cov tsom iav zoo li no yog ua raws li qhov tshwm sim ntawm defragmentation ntawm cov khoom nrog ib txhij nce hauv qhov tob ntawm daim teb, vim tias cov duab tau tsom raws nraim ntawm retina, uas txhim kho kev pom. Qhov tshwm sim no tseem hu ua cov nyhuv aperture ("peeping los ntawm lub qhov"). Tsis tas li ntawd, cov nyhuv ntawm lub qhov muag cov leeg raug txo, uas ua rau lawv so.

Cov neeg tsim khoom cog lus tias tsom iav nrog qhov, yog tias cov lus qhia tau ua raws nraim thiab siv tsawg kawg 30 feeb hauv ib hnub, tuaj yeem rov qab pom ib puas feem pua ntawm qhov pom hauv ib xyoos. Nws raug nquahu kom pib nrog 10 feeb. Thaum xub thawj, ib tug neeg muaj kev tsis xis nyob, tab sis dhau sij hawm nws tau siv rau nws. Nrog cov iav no, koj tuaj yeem nyeem, saib TV, ua haujlwm hauv computer, thiab ua lwm yam haujlwm.

Muaj lwm qhov kev xav. Ntau tus kws tshaj lij ntseeg tias iav nrog qhov yog ib qho khoom siv tsis muaj txiaj ntsig. Txij li thaum myopia yog xyaum tsis rov qab los ntawm nws tus kheej, uas yog, tsis muaj kev cuam tshuam sab nraud, ib tus tsis tuaj yeem tshem nws nrog ib qho kev cob qhia, ib tus tuaj yeem nres qhov tsis pom kev tsis pom kev. Farsightedness yog yooj yim dua los tiv thaiv los ntawm kev soj ntsuam qhov pom kev thiab ua ib ce tshwj xeeb rau lub qhov muag. Astigmatism feem ntau yog qhov tsis pom kev tsis pom kev, nrog kev kho kom raug nws tuaj yeem raug tshem tawm, tab sis myopia tseem yuav nyob.

Kev tshawb fawb los ntawm Asmeskas cov kws tshawb fawb uas tau sim tsom iav nrog qhov ua hauv Asmeskas tau pom tias cov cuab yeej no tsis muaj txiaj ntsig. Tsis yogkho qhov muag pom. Tsis tas li ntawd, raws li nws muab tawm, qhov no tsis yog kev txhim kho niaj hnub. Cov khoom siv zoo sib xws muaj nyob hauv Nrab Hnub nyoog. Tab sis dhau sij hawm, perforated daim hlau tau hloov nrog lo ntsiab muag, uas yooj yim dua thiab siv tau ntau dua.

Yog li txawm tias cov tsom iav zoo li txawv txawv, thiab zoo li cog lus tias yuav kho tau txuj ci tseem ceeb, nws tsim nyog xav txog seb qhov txuj ci tseem ceeb no muaj nqis npaum li cas. Tsis yog txhua yam tshaj tawm raws li kev siv thev naus laus zis yog.
