1.56 Semi Finished Progressive yees duab grey Optical Lenses

Lus piav qhia luv luv:

Lens refractive index yog siab dua, lub thinner lo ntsiab muag, qhov ntau dua qhov ceev, hardness thiab zoo dua, ntawm qhov tsis tooj, qhov qis dua qhov refractive index, lub lens tuab, qhov me dua qhov ntom, hardness kuj tsis zoo, dav dav iav ntawm siab hardness, Yog li qhov refractive index feem ntau yog nyob ntawm 1.7, thiab resin zaj duab xis hardness yog tsis zoo, lub refractive index yog tsawg, resin piece ntawm kev ua lag luam tam sim no yog qhov feem ntau refractive index ntawm 1.499 los yog li ntawd, me ntsis zoo dua yog lub ultra-thin version, uas muaj qhov ntsuas qhov ntsuas ntawm ib puag ncig 1.56 thiab tseem siv ntau tshaj.

Progressive multifocal lens

Yog ntau lub tsom iav tsom iav, lub ntsej muag lub ntsej muag curvature ntawm sab saum toj mus rau hauv qab ua ntej tsis tu ncua, lub zog refractive los ntawm koog tsev kawm ntawv nyob rau sab sauv ntawm lub lens yog nyob deb nrog, maj, nce tsis tu ncua, kom txog rau thaum yuav luag nyob rau hauv qab ntawm lub lens nrog cheeb tsam. mus txog tus lej ze li ntawm diopter, ob lub iav tuaj yeem pom, qhov kev ncua deb tuaj yeem pom ze dua, koj tuaj yeem pom cov khoom nyob deb. Cov lo ntsiab muag Progressive tau piav qhia tias yog "lens uas zoom," thiab ob lub tsom iav tuaj yeem siv los ua ib qho ntxiv ntawm tsom iav. Piv txwv li, yog tsim rau cov menyuam kawm ntawv nyeem thiab sau cov tub ntxhais kawm siv lub lens (saib saib ntawm lub blackboard, nyeem cov phau ntawv, homework thiab lwm yam kev xav tau), haum rau dawb-caj dab neeg coob tus qaug zog tiv thaiv ntawm lub lens (kom hloov mus rau lub nyob deb, nruab nrab thiab ze qhov muag hloov, yooj yim rau kev ua haujlwm), yoog rau cov neeg laus thiab cov laus d pom kev ua haujlwm zoo (dawb kev cai nkhaus nto, zoo, nruab nrab, ze rau kev hloov, tsis kiv taub hau nthuav dav).

Qhuav Taw Qhia

Lub ntsiab refractive index ntawm lub lens muaj xws li: 1.56, 1.60, 1.67, 1.71, 1.74 thiab hais txog. Qhov siab dua qhov refractive index ntawm lub lens, qhov thinner thiab lighter lub lens. Txawm li cas los xij, qhov siab dua qhov refractive index ntawm lub lens yog, qhov zoo dua. Feem ntau, qhov siab dua qhov refractive index ntawm lub lens yog, qhov qis dua tus naj npawb Abbe thiab qhov pom tseeb dua qhov dispersion yog.
