Abathengisi abakhulu be-optical baseIndiya i-D2C (njengeLensKart kunye nezinye iimpawu eziphambili) bavule amawaka eevenkile zanamhlanje kuzwelonke. Kwiimveliso zabo zokuqala ze-intanethi kunye ne-intanethi eziqhuba ithrafikhi, iilensi ezili-1.56 zokulwa nokudinwa / ukukhanya okuluhlaza okwesibhakabhaka zezona zinto zithengiswa kakhulu.

III. Kutheni iilensi eziyi-1.56 zingaxhaphakanga eYurophu naseMelika

1. Imigangatho eyahlukeneyo yoHlelo lweZinto

Iimarike ze-optical zamazwe ngamazwe zihlala zahlulahlula izinto ze-lens zibe ziindidi ezintathu:

• Isalathisi esiphantsi — 1.50 (CR-39), igxile kumgangatho wokukhanya.
• Isalathisi esiphakathi — 1.60 (njenge-MR-8), ilinganisa ubuncinci kunye nokusebenza kokukhanya.
• I-high-index — 1.67+ (MR-7, Mr-10, njl.njl.), ukukhaphukhaphu nokubhitya okupheleleyo.

I-1.56 index iphakathi kweendidi ezahlukeneyo. Ayithathwa njengelensi eqhelekileyo ene-low index okanye ilensi yokwenyani ene-high index, kodwa ngokwendalo ibekelwe ecaleni luluhlu oluphambili lwezinto ezithengiswayo.

2. Imigangatho Yezomthetho Nokhuseleko (eMelika)

I-FDA yase-US inyanzelisa iimfuno ezingqongqo kakhulu zokumelana nokuchaphazeleka kweelensi zokukhanya, kuquka Uvavanyo lweBhola yokuLahlaIilensi zeresin eziqhelekileyo ze-1.56 zibuthathaka kwaye azinawo amandla okumelana nempembelelo (zinokuqhekeka lula). Ngenxa yoko, kunzima ukuba zihlangabezane nemigangatho yokhuseleko efunekayo kwiilensi ezingenamphetho okanye ezingenamphetho emva kokucubungula.

3. Iingxabano malunga nokubekwa kweMarike

Abathengi baseYurophu naseMelika kudala belandela umgaqo othi "ufumana oko ukuhlawulelayo" xa bekhetha iilensi:

• Khetha iilensi ze-CR-39 ezingabizi kakhulu
• Okanye uhlawulele ngaphezulu iilensi ezincinci ezine-high-index

Kubo, "ukhetho oluphakathi" olunikezelwa ziilensi eziyi-1.56 ludla ngokungabi naxabiso lifanelekileyo.

IV. Isiphelo

I-1.56 refractive index isenokungabi nabukhazikhazi bobuchwepheshe be-optical obuphambili, kodwa isombulule enye yezona ndawo zinzima kwimarike ye-eyewear yase-Asia ngeyona ndlela isebenzayo: ukuvumela abantu abanee-prescription ezinamandla ukuba bonwabele iilensi ezincinci nezikhaphukhaphu ngexabiso eliphantsi kakhulu.
