1.49 Ib Vision UC

Lus piav qhia luv luv:

Lub refractive index ntawm lub lens, 1.49, 1.56, 1.60, 1.67, 1.71, 1.74 nyob rau sab sauv cim ntawm lub lens yog hais txog lub refractive index ntawm lub lens. Rau cov tsom iav myopic, qhov siab dua qhov ntsuas qhov ntsuas ntawm lub lens, qhov thinner ntawm ntug ntawm lub lens, ntawm qhov chaw uas lwm qhov tsis zoo ib yam.

Nyob rau tib lub degree, qhov siab dua qhov refractive index, lub lens thinner. Lub refractive index ntawm 1.50 los yog 1.56 yog haum rau xaiv nyob rau hauv 300 degrees, lub refractive index ntawm 1.56 los yog 1.60 yog haum rau xaiv ntawm 300 thiab 500 degrees, lub refractive index ntawm 1.67 yog haum rau xaiv ntawm 500 thiab 800 degrees, thiab refractive. index ntawm 1.70 thiab 1.74 yog haum rau xaiv saum toj no 800 degrees.

Raws li peb txhua tus paub, qhov zoo tshaj plaws ntawm 1.50 refractive index yog tias nws muaj tus lej Abbe siab ntawm 58, ua raws li tus nqi pheej yig, uas yog tshwj xeeb tshaj yog haum rau cov neeg uas tsis tshua muaj myopia.

Qhuav Taw Qhia

Tus menyuam xaiv lub lens nrog qhov ntsuas qhov ntsuas ntawm 1.50. Yog tias koj tus menyuam muaj teeb meem tsis pom kev, nws tsis haum rau hnav tiv thaiv thiab tswj cov lo ntsiab muag, lossis cov peev nyiaj tsis tso cai siv cov kev tiv thaiv thiab tswj cov lo ntsiab muag. Tom qab ntawd cov lo ntsiab muag zoo tib yam yog qhov zoo tshaj plaws rau cov menyuam yaus (myopia tsawg dua 400 degrees). Nws yog 1.50 index lens.

1. High Abbe tooj: txo cov nyhuv ntawm dispersion ntawm clarity. Tshwj xeeb tshaj yog nyob rau hauv cov menyuam yaus farsighted, qhov chaw thickness yog loj, tus naj npawb Abbe tseem ceeb tshwj xeeb. (Lub tib neeg lub qhov muag muaj tus naj npawb Abbe ntawm 58.6, thaum lub 1.50 refractive index lens muaj tus naj npawb Abbe ntawm 58)
