Slab Off rau kev ua tiav cov duab fused rau anisometropia

Peb puas tau txais cov xaj uas xav tau Slab Off, thiab peb yeej ib txwm txhawj txog cov neeg siv khoom xav tau.
Xov xwm zoo uas peb nyuam qhuav teeb tsa kev xaiv ntawm Slab Off hauv peb lub chaw kuaj mob, los txhawb cov neeg mob cov xaj thaum muaj kev xav tau.

Qhov tseeb yog tias thaum hnav cov iav tsom iav uas nce zuj zus, tus neeg hnav yuav tsum saib qis dua qhov ntawd, cov teebmeem prismatic ntawd yuav siab dua. Thiab yog tias tus neeg hnav muaj lub zog iav tsis sib npaug (anisometropia) loj dua 1.50D, nws yuav pom kev tsis meej, pom ob sab, lossis nws yuav xav tias nruj heev.

Raws li pom hauv cov duab hauv qab no, 2 # daim duab qhia thaum pom los ntawm qhov chaw qis dua cov duab los ntawm ob lub lens ntawm lub zog sib txawv yuav txawv, thiab qhov sib txawv no ua rau cov duab tsis sib xyaw hauv qhov muag; 3 # daim duab qhia txog kev ua haujlwm ntawm prism lens; thiab 4 # daim duab qhia txog kev sib xyaw ua ke ntawm cov duab tau ua tiav thaum ntxiv prism lens.

Yog li ntawd, yog tias muaj teeb meem ntawm kev pom tsis meej lossis kev pom ob npaug tshwm sim nrog anisometropia, tus kws kho qhov muag yuav teeb tsa lub lens nrog kev them nyiaj rau hauv tus ncej, raws li pom hauv 3 # & 4 # cov duab.
Thiab peb txoj kev daws teeb meem yog tsim nws los ntawm kev sib tsoo dawb kom ntxiv Slab Off prism rau ntawm cov iav lo ntsiab muag. Tus qauv Slab off yuav pom muaj nyob rau hauv lub zog minus lossis weaker plus lens.

Peb yuav tsum nco ntsoov tias Slab Off ua rau muaj thaj chaw tsis sib xws thiab pom kev tsis meej, feem ntau ntawm 3-7 hli nyob ntawm qib kev tswj hwm thiab kev ua tau zoo uas peb tuaj yeem siv rau cov tshuab.
