Txhawm rau kom tsim nyog rau EN379 qhov ntsuas, nws pib-tso lub lens tau kuaj thiab ntsuas hauv 4 pawg: Optical class, Diffusion of light class, Variations in luminous transmittance class, and Angle dependence on luminous transmittance class. Txhua pawg tau ntsuas ntawm qhov ntsuas ntawm 1 txog 3, nrog 1 yog qhov zoo tshaj plaws (zoo meej) thiab 3 qhov phem tshaj.
Optical class (qhov tseeb ntawm qhov muag) 3/X/X/X
Koj paub yuav ua li cas distorted ib yam dab tsi tuaj yeem saib hauv dej? Qhov no yog dab tsi chav kawm no yog txhua yam hais txog.

Txhua lub kaus mom saum toj kawg nkaus tuaj yeem xav kom muaj qhov ntsuas ntawm 1, txhais tau tias nws tsis muaj impurities thiab meej meej.
Variations nyob rau hauv luminous transmittance chav kawm (lub teeb los yog tsaus nti nyob rau hauv lub lens) X / X / 3 / X
Cov kaus mom hlau tsis siv neeg tsaus nti feem ntau muab kev hloov kho ntxoov ntxoo ntawm # 4 - # 13, nrog # 9 yog qhov tsawg kawg nkaus rau vuam.

Qib 1 yuav xa ib qho ntxoov ntxoo thoob plaws lub lens tag nrho, qhov twg 2 lossis 3 yuav muaj qhov sib txawv ntawm cov ntsiab lus sib txawv ntawm lub lens, uas yuav ua rau qee qhov chaw ci dhau los lossis tsaus dhau.
Lub kaum sab xis ntawm luminous transmittance X / X / X / 3
Cov chav kawm no ntsuas lub lens rau nws lub peev xwm los muab qhov sib npaug ntawm qhov ntxoov ntxoo thaum saib ntawm lub kaum sab xis (vim tias peb tsis yog weld cov khoom ncaj qha rau pem hauv ntej ntawm peb). Yog li qhov ntsuas no yog qhov tseem ceeb tshwj xeeb rau txhua tus neeg vuam cov nyuaj mus txog thaj chaw. Nws kuaj pom qhov pom tseeb yam tsis muaj qhov ncab, thaj chaw tsaus, qhov muag tsis pom, lossis teeb meem nrog saib cov khoom ntawm lub kaum sab xis. A 1 ntsuam xyuas txhais tau hais tias qhov ntxoov ntxoo nyob twj ywm tsis muaj teeb meem qhov pom lub kaum ntse ntse.
