Lambarrada ku qoran warqadda daawada indhahaaga waxay la xiriiraan qaabka indhahaaga iyo xoogga aragtidaada. Waxay kaa caawin karaan inaad ogaato inaad leedahay iyo in kale aragti dhow, aragti fog ama aragti fog - iyo heerka ay gaarsiisan tahay.
Haddii aad taqaanid waxaad raadineyso, waxaad fahmi kartaa lambarrada iyo soo gaabinta ku qoran shaxda daawadaada.
OD iyo OS: Mid il kasta loogu talagalay
Dhakhaatiirta indhaha waxay adeegsadaan soo gaabinta "OD" iyo "OS" si ay u muujiyaan indhahaaga midig iyo bidix.
● OD waa ishaada midig. OD waa mid gaaban oo loo yaqaan oculus dexter, weedha Laatiinka ah ee "isha midig."
● OS waa ishaada bidix. OS waa mid gaaban oo loogu talagalay oculus sinister, Laatiin ahaanna waa "isha bidix."
Daawadaada daawada indhaha ayaa sidoo kale laga yaabaa inay leedahay tiir lagu calaamadeeyay "OU." Kani waa soo gaabintauterque oculus, oo macnaheedu yahay "labada indhood" oo ku qoran Laatiin. Ereyadan la soo gaabiyay waa kuwo caadi ah marka loo eego daawooyinka loo qoro muraayadaha indhaha. muraayadaha indhaha la iska arko iyo daawooyinka indhaha, laakiin dhakhaatiirta iyo xarumaha caafimaadka qaarkood waxay doorteen inay casriyeeyaan daawooyinka indhaha iyagoo adeegsanayaRE (isha midig)iyoLE (isha bidix)halkii laga isticmaali lahaa OD iyo OS.
Sphere (SPH)
Sphere waxay tilmaamaysaa xaddiga awoodda muraayadda ee loo qoray si loo saxo aragtida dhow ama aragtida fog. Awoodda muraayadda waxaa lagu cabbiraa diopters (D).
● Haddii lambarka cinwaankan ku hoos jira uu la socdo calaamadda laga jaray (–),waxaad tahay qof aan aragti fog lahayn.
● Haddii lambarka cinwaankan ku yaal uu leeyahay calaamadda lagu daray (+),waxaad tahay qof aragti fog leh.
Dhululubo (CYL)
Dhululubo waxay tilmaamaysaa xaddiga awoodda muraayadda ee loo baahan yahayaragtida astigmatism-kaWaxay had iyo jeer raacdaa awoodda wareegga ee ku jirta warqadda muraayadaha indhaha.
Lambarka ku jira tiirka dhululubada wuxuu yeelan karaa calaamad laga jaray (sixitaanka astigmatism-ka aragtida fog) ama calaamad lagu daray (astigmatism-ka aragtida fog).
Haddii aysan waxba ka muuqan tiirkan, ma lihid astigmatism, ama heerkaaga astigmatism aad ayuu u yar yahay oo uma baahna in la saxo.
Dhidibka
Axis wuxuu qeexayaa muraayadda meridian-ka oo aan lahayn awood dhululubo ahastigmatism-ka saxda ah.
Haddii warqadda daawada muraayadda indhaha ay ku jirto awood dhululubo, waxay sidoo kale u baahan tahay inay ku jirto qiime dhidib ah, kaas oo raacaya awoodda dhululubo.
Dhidibka waxaa lagu qeexaa tiro u dhaxaysa 1 ilaa 180.
● Lambarka 90 wuxuu u dhigmaa isha toosan ee meridian-ka.
● Lambarka 180 wuxuu u dhigmaa meridian-ka toosan ee isha.
Ku dar
"Ku dar" waaawood weynayn oo lagu daraywaxaa lagu dabaqaa qaybta hoose ee muraayadaha indhaha badan leh si loo saxo presbyopia - aragtida fog ee dabiiciga ah ee dhacda marka da'da la gaaro.
Lambarka ka muuqda qaybtan daawada dhakhtarku qoray had iyo jeer waa awood "plus", xitaa marka aadan arkin calaamadda plus. Guud ahaan, waxay u dhaxaysaa +0.75 ilaa +3.00 D waxayna noqon doontaa awood isku mid ah labada indhoodba.
Prism
Tani waa xaddiga awoodda prismatic, oo lagu cabbiro diopters-ka prism ("pd" ama saddexagal marka la qoro gacanta xorta ah), oo loo qoray in lagu magdhaboiswaafajinta ishadhibaatooyinka.
Boqolkiiba yar oo ka mid ah daawooyinka indhaha lagu qoro ayaa ku jira cabbiraadda prism.
Marka la joogo, xaddiga prism-ka waxaa lagu muujiyay cutubyada Ingiriisiga ee mitirka ah ama jajaban (tusaale ahaan 0.5 ama ½), jihada prism-kana waxaa lagu muujiyay iyadoo la xusayo booska qaraabada ah ee "saldhigga" (geeska ugu dhumucda badan).
Afar soo gaabin ayaa loo isticmaalaa jihada prism: BU = saldhig kor; BD = saldhig hoose; BI = saldhig gudaha (dhinaca sanka qofka xiran); BO = saldhig dibadda (dhinaca dhegta qofka xiran).
