Kungani Kufanele Ukhethe I-CR-39 Optical Lens?

I-Crystal Vision (CR) amalensi ekhwalithi ephezulu enziwe enye yezinkampani zamalensi ezinkulu emhlabeni.
I-CR-39, noma i-allyl diglycol carbonate (ADC), i-polymer yepulasitiki evame ukusetshenziswa ekwenzeni amalensi engilazi yamehlo.
Isifinyezo simelela “i-Columbia Resin #39”, okwakuyifomula yama-39 yepulasitiki ebeka i-thermosetting eyakhiwa iphrojekthi ye-Columbia Resins ngo-1940.
Iphethwe yi-PPG, le nto iguqula ukwenziwa kwamalensi.
Ingxenye esindayo njengengilazi, mancane kakhulu amathuba okuthi ingaphahlazeka, kanye nekhwalithi yokubona icishe ilingane nengilazi.
I-CR-39 iyashiswa futhi ithululelwe ekubunjweni kwengilazi yekhwalithi ye-optical - ukulungisa izimfanelo zengilazi eduze kakhulu.

Isibani esiluhlaza okwesibhakabhaka-Violet

Olunye ushintsho olukhulu ukukhanya okuluhlaza okwesibhakabhaka. Ukukhanya okuluhlaza okwesibhakabhaka akukusha - kuyingxenye ye-spectra ebonakalayo.

Ilanga bekungumthombo owodwa omkhulu wokukhanya okuluhlaza okwesibhakabhaka kusukela ekuqaleni kwesikhathi ngokuchayeka ngaphandle izikhathi ezingu-500 ezinkulu kunangaphakathi. Ushintsho ekukhanyeni okuluhlaza okwesibhakabhaka luza nolwazi lwethu ngomthelela wako ohlelweni lokubukwayo. Ngenxa yocwaningo olwenziwe yiParis Vision Institute kanye ne-Essilor, manje sesiyazi ukuthi iningi lezingulube ze-retinal cell ukufa kwenzeka lapho lawa maseli evezwa amabhande okukhanya okuluhlaza okwesibhakabhaka phakathi kwe-415nm-455nm, enenani eliphakeme ku-435nm.

Zilungiselele ngalawa malensi okuhlunga aluhlaza alungile.

Yiziphi izixazululo esinazo zokunciphisa ukukhanya okuluhlaza okwesibhakabhaka?

Akuwona wonke ukukhanya okuluhlaza okungalungile kuwe. Nokho, Harmful Blue Light.

Ikhishwa kumadivayisi asetshenziswa iziguli zakho nsuku zonke—njengamakhompyutha, ama-smartphone, namathebulethi.

Futhi njengoba u-60% wabantu uchitha amahora angaphezu kwayisithupha ngosuku emishinini yedijithali, iziguli zakho cishe zizobuza ukuthi yini ezingayenza ukuze zivikele amehlo azo kulokhu kuchayeka isikhathi eside ku-Harmful Blue Light.

Okuthathwayo Okubalulekile

• Ukukhanya okuluhlaza okwesibhakabhaka-violet okuvela ku-415-455 nm kuye kwafakazelwa njengesifaki sokucindezeleka se-oxidative esiqinile kanye ne-inhibitor yokuzivikela, ngaleyo ndlela kungenye yezindlela zokukhanya eziyingozi kakhulu ze-retina.

• Ingozi engaba khona exhunyaniswe nokwanda kokuchayeka kokukhanya okuluhlaza okwesibhakabhaka ingashintshwa ngenxa yobuchwepheshe bakamuva belensi ye-ophthalmic.

• Imfundo yesiguli ibalulekile ekuqwashiseni ngazo zombili imiphumela eyingozi yokukhanya okuluhlaza kanye nezixazululo ezikhona zokuvimbela.

• Ukukhanya okuluhlaza okwesibhakabhaka kwakhiwe ngemisebe eyingozi (blue-violet) kanye nenzuzo (blue-turquoise). Kubalulekile ukuthi ilensi ye-ophthalmic ivimbe eyokuqala futhi idlule kweyakamuva.

• Uma uqhathanisa izixazululo ezihlukahlukene ze-optical zokuhlunga ukukhanya okuluhlaza okwesibhakabhaka kubalulekile ukukhumbula ukuthi akukona nje kuphela inani lokukhanya okuluhlaza okwesibhakabhaka-violet okuvinjiwe kubalulekile kodwa futhi amabhande we-wavelength avinjiwe.
