Feem ntau, cov tsom iav myopia uas hloov xim tsis yog tsuas yog coj kev yooj yim thiab kev zoo nkauj xwb tab sis kuj tuaj yeem tiv taus ultraviolet thiab glare, tuaj yeem tiv thaiv lub qhov muag, qhov laj thawj rau kev hloov xim yog tias thaum lub lens ua, nws tau sib xyaw nrog cov khoom siv uas rhiab rau lub teeb, xws li silver chloride, silver halide (hu ua silver halide), thiab me ntsis ntawm cov catalyst tooj liab oxide. Thaum twg cov silver halide raug ci los ntawm lub teeb muaj zog, lub teeb yuav lwj thiab ua ntau cov nyiaj dub sib npaug hauv lub lens. Yog li ntawd, lub lens yuav zoo li tsaus ntuj thiab thaiv kev hla ntawm lub teeb. Lub sijhawm no, lub lens yuav dhau los ua xim, uas tuaj yeem tiv thaiv lub teeb kom ua tiav lub hom phiaj ntawm kev tiv thaiv lub qhov muag.

Cov iav uas hloov xim yuav tsaus ntuj thaum lub hnub ci. Thaum lub teeb ploj mus, nws yuav ci dua. Qhov no ua tau vim tias cov siv lead ua los ntawm cov nyiaj halide ua haujlwm.
Nyob rau hauv ib txwm muaj xwm txheej, nws ua rau cov iav tsom iav pom tseeb zoo meej. Thaum raug tshav ntuj, cov nyiaj hauv cov siv lead ua ke raug sib cais, thiab cov nyiaj dawb tsim cov khoom me me hauv lub lens. Cov khoom me me nyiaj no yog cov khoom tsis sib xws, sib txuas ua ke uas tsis tuaj yeem xa lub teeb tab sis nqus nws, ua rau lub lens tsaus ntuj. Thaum lub teeb qis, cov siv lead ua ke rov qab los thiab lub lens rov qab mus rau nws lub xeev ci.
