1.49 Ib Lub Zeem Muag UC

Kev Piav Qhia Luv:

Tus nqi refractive index ntawm lub lens, 1.49, 1.56, 1.60, 1.67, 1.71, 1.74 ntawm lub cim sab saud ntawm lub lens txhais tau tias tus nqi refractive index ntawm lub lens. Rau cov tsom iav myopic, tus nqi refractive index ntawm lub lens siab dua, qhov ntug ntawm lub lens nyias dua, vim tias lwm yam kev teeb tsa zoo ib yam.

Nyob rau tib theem, qhov siab dua qhov refractive index, qhov nyias dua lub lens. Qhov refractive index ntawm 1.50 lossis 1.56 yog qhov tsim nyog rau kev xaiv hauv 300 degrees, qhov refractive index ntawm 1.56 lossis 1.60 yog qhov tsim nyog rau kev xaiv ntawm 300 thiab 500 degrees, qhov refractive index ntawm 1.67 yog qhov tsim nyog rau kev xaiv ntawm 500 thiab 800 degrees, thiab qhov refractive index ntawm 1.70 thiab 1.74 yog qhov tsim nyog rau kev xaiv saum 800 degrees.

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

Kev Taw Qhia Txog Kev Tsim Khoom

Tus me nyuam xaiv lub lens uas muaj refractive index ntawm 1.50. Yog tias koj tus me nyuam muaj teeb meem pom kev, nws tsis tsim nyog hnav cov lens tiv thaiv thiab tswj, lossis cov peev nyiaj tsis pub siv cov lens tiv thaiv thiab tswj. Yog li ntawd, cov lens ib txwm yog qhov tsim nyog tshaj plaws rau cov me nyuam (myopia tsawg dua 400 degrees). Nws yog lub lens index 1.50.

1. Tus lej Abbe siab: txo qhov cuam tshuam ntawm kev tawg ntawm qhov pom tseeb. Tshwj xeeb tshaj yog rau cov menyuam yaus uas pom kev deb, qhov twg qhov tuab ntawm qhov chaw nruab nrab loj, tus lej Abbe tseem ceeb heev. (Lub qhov muag tib neeg muaj tus lej Abbe ntawm 58.6, thaum lub lens refractive index 1.50 muaj tus lej Abbe ntawm 58)
