Vadikanwi shamwari, paunosarudza magirazi, unowanzozvibvunza kuti ungasarudza sei zvinhu zve lens?
Nhasi ndiri kukupa ruzivo rutsva
Chaizvoizvo, hazvisi zvakaoma kusarudza magirazi akanaka.Chokutanga pane zvose, tinofanira kufunga nezvezvinhu zvemagirazi.Zvinhu zvakasiyana-siyana zvine maitiro akasiyana.
Heano zvimwe zvezvinonyanya kufarirwa nemaziso zvinhu:
① Girazi (rinorema/risina kusimba/kusapfeka)
Magirazi egirazi anoratidzirwa nekujeka kwepamusoro uye kuoma kwakanyanya.Chinoipa ndechekuti zviri nyore kuputsika uye zvinorema.Iye zvino isu kazhinji hatikurudzire kutenga rudzi urwu rwe lens.
②CR39 lens (yakareruka / isingaite brittle / yakawanda isingapfekere)
Resin lenses parizvino anonyanya kushandiswa uye ari emhando yepamusoro zvinhu.Chakanakira ndechekuti yakareruka, haibatike, uye haisi nyore kutyora.Panguva imwecheteyo, inotora ultraviolet rays zviri nani pane girazi lenzi, uye inogonawo kuwedzera anti-ultraviolet zvinhu.
③PC (yakareruka / isina brittle / isina kupfeka-inodzivirira)
PC lenzi ndeye polycarbonate, inova iyo thermoplastic zvinhu.Chakanakira ndechekuti yakareruka uye yakachengeteka.Inokodzera magirazi asina rimless.Inowanzoenderana nekugadzirwa kwemagirazi ezuva, ndiko kuti, magirazi emasikati emagirazi.
④Malenzi echisikigo (akaoma uye asingapfeki)
Malenzi echisikigo haawanzo kushandiswa ikozvino.Semuenzaniso, quartz ine zvakanakira kuomarara kwepamusoro uye kusagadzikana kwekusapfeka, asi chakashata ndechekuti haigone kunyatsotora ultraviolet uye infrared rays.
Saka shamwari, kana iwe ukapfeka magirazi, zvinokurudzirwa kushandisa resin lenses.Ichi chinyorwa chinoshandiswawo zvakanyanya parizvino ~ ~
