1. Ndeapi marudzi emidziyo yelenzi iripo?
Zvishandiso zvechisikigo: dombo rekristaro, kuomarara kwepamusoro, zvisiri nyore kugaya, zvinogona kutumira ultraviolet mwaranzi, uye ine birefringence.
Artificial zvinhu: zvinosanganisira inorganic girazi, organic girazi uye optical resin.
Inorganic girazi: Inonyungudutswa kubva kune silica, calcium, aluminium, sodium, potasium, nezvimwewo, nekujeka kwakanaka.
Plexiglass: Iyo kemikari inoumbwa ndeye polymethyl methacrylate.
Optical resin: Iyo kemikari inoumbwa ndeye propylene diethylene glycol carbonate. Zvakanakira huremu huremu, kukanganisa kupikisa, kuumbwa kwekukanda, uye kudhaya nyore.
2. Ndezvipi zvakanakira uye kuipa kweresin lenzi?
Zvakanakira: huremu huremu, husina kusimba, hapana mipendero kana makona kana yaputsika, yakachengeteka
Kukanganisa: ma lens asingapfekeki akakora uye mutengo wakakwira zvishoma
3. Chii chinonzi bifocal lenzi?

5. Chii chinonzi lenzi yakaoma?
Kuomesa, sekureva kunoita zita, zvinoreva kuti lenzi yakaoma kupfuura yakajairika. Malenzi akaomarara ane super wear resistance. Nheyo yacho ndeyokuti pamusoro pelens yakaputirwa neakakosha ekupedzisira-akatsetseka zvimedu zvinoomesa kurapa kuti uwedzere kupfeka kuramba kwelens uye kurebesa hupenyu hwesevhisi. .
