1.71 Hal aragga HMC ee muraayadaha indhaha

1.71 Hal aragga Halliga ah ee HMC muraayadaha indhaha ee muuqaalka leh

Sharaxaad Gaaban:

1.71 lens Magaca buuxa 1.71 lens index refractive, oo leh index refractive sare, gudbinta sare, sifooyinka nambar Abbe sare, xaalad isku mid ah myopia degree, si weyn u dhimi kara dhumucda lens, hoos u tayada lens, isla waqti, ka dhig muraayadda mid saafi ah oo dhalaalaya, ma fududa in la kala firdhiyo hadhuudh qaansoroobaad.Waxaa la ogaaday in ku darista resin sulfide cyclic ee walxaha lensku ay wanaajin karto index refractive of lens, laakiin aad u badan xabagta sulfide cyclic waxay horseedi doontaa dhimista gudbinta iftiinka iyo dildilaaca walxaha.Iyada oo si sax ah loo xakameynayo nuxurka resin sulfur ee 1.71KR, lens-ka 1.71 wuxuu gaaraa index refractive sare iyo lambarka abbe iyadoo la hubinayo gudbinta iftiinka wanaagsan, kala firdhisanaanta hoose iyo aragti cad.

Tusmada lensku waxa ay tilmaamaysaa tusmada dib-u-soo-celinta (haddii kale loo yaqaan index refractive) ee walxaha muraayadda ee muraayadaha indhaha.Waa nambar qiyaaseed qaraabo ah oo qeexaya sida wax-ku-oolnimada leh ee walaxdu u leexiso iftiinka.Dib-u-soo-celinta iftiinka waxay ku xirnaan doontaa sida degdegga ah ee laftiisu u dhex maro muraayadda.

Agabka lens-ku waxa lagu kala saaray tusmahooda dib u soo celinta.Tilmaantan refractive-ka ah waa saamiga xawaaraha iftiinka marka uu hawada ku socdo illaa xawaaraha iftiinka marka uu dhex marayo qalabka muraayadda.Waa tilmaan muujinaysa inta iftiinku foorarsan yahay marka uu dhex socdo muraayadda.Iftiinku waa la jajabiyaa, ama foorarsan yahay, dusha hore ee muraayadda, ka dibna mar kale marka uu ka soo baxo lenska. Qalabka cufan ayaa si aad ah u leexiya iftiinka, sidaas darteed ma aha wax badan oo loo baahan yahay si loo gaaro saameyn isku mid ah oo la mid ah maadada cufan.Sidaa darteed muraayadda ayaa laga dhigi karaa mid khafiif ah, iyo sidoo kale khafiif ah.

Muraayadaha muraayadaha indhaha ee caadiga ah, badhtamaha muraayadaha ayaa khafiif ah cidhifyada dibaddana waa dhumuc weyn yihiin si ay u fududeeyaan dib-u-soo-celinta taas oo ah waxa ka dhigaya muraayadaha dhakhtarku inay shaqeeyaan!Muraayadaha tusmada sare waxay leeyihiin index sare oo dib-u-gurasho ah marka loo eego muraayadaha caadiga ah, taas oo macnaheedu yahay uma baahna inay noqdaan kuwo dhumuc weyn leh hareeraha geesaha si ay u noqdaan kuwo waxtar leh.

Muraayadaha index-sare waxay ka dhigan yihiin in muraayadda lafteedu ay noqon karto mid khafiif ah oo fudud labadaba.Tani waxay u oggolaanaysaa muraayadahaagu inay noqdaan kuwo moodada ah oo raaxo leh intii suurtagal ah.Lenses-index-ka sare ayaa si gaar ah faa'iido u leh haddii aad haysato warqad xoog leh oo muraayad indhaha ah oo loogu talagalay aragga dhow, aragti fog, ama astigmatism.Si kastaba ha ahaatee, xitaa kuwa leh warqadda muraayadda indhaha ee hoose waxay ka faa'iideysan karaan lenses index sare.

1.71 waa badeeco weerar celis ah.Guud ahaan, mar kasta oo uu sareeyo index refractive, hoos ayuu u dhigayaa lambarka Abbe.Nambarka 1.67 Abbe waa 32, 1.74 waa 33, 1.71na wuxuu sameyn karaa 37. Weerarkii rogaal-celinta waa lagu guuleystay.Nambarka Abbe waa sarreeyaa, kala firdhiskuna wuu hooseeyaa, kaas oo si fudud u cad.1.67 aad ayuu uga jaban yahay 1.74, laakiin aad buu u dhumuc weyn yahay xagga dhererka.1.74 runtii waa dhuuban, laakiin qiimuhu aad buu u sarreeyaa, dhexda dhexe waa mid aad u weyn.Saaxiibo badan ayaa jeebkooda ku dooran kara 1.67 oo kaliya.1.71 ayaana buuxinaysa farqigaas.
