Kuyezetsa maso ndi mankhwala a magalasi

Ngati mukufuna kukonzedwa m'masomphenya mutayesedwa m'maso, dokotala wanu wamaso kapena diso lanu adzakudziwitsani ngati mukuyandikira kapena mumaonera patali. Amatha kukuwuzani kuti muli ndi vuto la astigmatism.

Mukapezeka ndi matenda aliwonse, mudzapatsidwa mankhwala okongoletsa m'maso. Mankhwala anu adzakhala ndi mawu achidule monga:

• OD
• OS
• SPH
• CYL

Kodi mukudziwa tanthauzo la izi? Timafotokozera.

Kodi OD vs. OS amatanthauza chiyani?

Gawo limodzi lomvetsetsa mankhwala ochokera kwa dotolo wanu ndikudziwa OD ndi OS. Izi ndi zidule chabe za mawu achi Latin:

• OD ndichidule cha "oculus dexter" chomwe chiri Chilatini kutanthauzira "diso lakumanja."
• OS ndichidule cha "oculus sinister" chomwe ndi Chilatini kwa "diso lakumanzere."

Mankhwala anu atha kukhala ndi cholembera cha OU, chomwe ndi chidule cha "oculus uterque," Chilatini chotanthauza "maso onse awiri."

Ngakhale OS ndi OD ndizachidule zachikhalidwe zomwe zimagwiritsidwa ntchito popangira magalasi amaso, magalasi olumikizirana, ndi mankhwala amaso, pali madotolo ena omwe asintha mafomu awo posintha OD ndi RE (diso lakumanja) ndi OS ndi LE (diso lakumanzere).

Zidule zina pazakumwa yanu yamagalasi

Zolemba zina zomwe mungaone pazakumwa zanu zamagalasi ndi SPH, CYL, Axis, Add, ndi Prism.

SPH

SPH ndichidule cha "sphere" chomwe chikuwonetsa mphamvu ya mandala omwe dokotala wanu akukulemberani kuti muwongolere masomphenya anu.

Ngati mukuyandikira (myopia), chiwerengerocho chidzakhala ndi chizindikiro chotsitsa (-). Ngati mukuwona patali (hyperopia), chiwerengerocho chidzakhala ndi chikwangwani chowonjezera (+).

CYL

CYL ndichidule cha "silinda" chomwe chikuwonetsa mphamvu yamagalasi yomwe dokotala wanu akukupatsani kuti athetse vuto lanu. Ngati mulibe nambala mgawo ili, ndiye kuti dokotala wanu sanapeze astigmatism kapena astigmatism yanu sikuyenera kukonzedwa.

Olamulira

Olamulira ndi nambala kuyambira 1 mpaka 180. Ngati dokotala wanu waphatikiza mphamvu yamphamvu, padzakhalanso mtengo wolumikizira posonyeza kuyika. Olamulira amayeza mu madigiri ndipo amatanthauza komwe astigmatism ili pa cornea.

Onjezani

Onjezerani imagwiritsidwa ntchito pamagalasi amitundu yambiri kuti muwonetse mphamvu yowonjezera yowonjezera kumunsi kwa mandala.

Mwala

Prism imangowonekera pamanambala ochepa. Amagwiritsidwa ntchito pamene dokotala akuwona kuti kubwezeredwa kwa mayendedwe a diso ndikofunikira.

Zolemba pamankhwala anu akhungu

Mukamayang'ana mankhwala anu agalasi lagalasi, mutha kuwona malingaliro omwe mandala anu aphatikizira. Izi ndizosankha zokha ndipo zimatha kubweza zina:

• Magalasi a Photochromic.Amatchulidwanso kuti magalasi amtundu wosiyanasiyana ndi magalasi opepuka, izi zimapangitsa magalasiwo kukhala amdima akakhala padzuwa.
• Coating Anti-chimawala coating kuyanika.Zomwe zimatchedwanso AR zokutira kapena zokutira zowala, zokutira izi zimachepetsa zowunikira kuti kuwala kambiri kudutse pamagalasi.
• Magalasi opita patsogolo.Awa ndi magalasi ophatikizika opanda mizere.

Chithandizo chanu cha magalasi oyang'ana pagalasi sichomwe mumalemba

Pomwe cholembera chanu chagalasi lakumaso chili ndi chidziwitso chonse chofunikira kuti mugule magalasi amaso, chilibe chidziwitso chofunikira pogula magalasi olumikizirana nawo.

Izi zikuphatikiza:

• mandala awiri
• pamapindikira kumbuyo kwa mandala olumikizirana
• wopanga mandala ndi dzina lake

Dokotala wanu nthawi zina amasintha kuchuluka kwa mphamvu zowongolera pakati pa magalasi ndi magalasi olumikizirana kutengera kutalika kwa mandalawo ndi diso. Magalasi ali pafupifupi mamilimita 12 (mm) kutali ndi diso pomwe magalasi olumikizirana amakhala molunjika pamwamba pa diso.

Tengera kwina

Kutengera ndi momwe zinthu ziliri - pakali pano mukugwiritsa ntchito zokongoletsa m'maso, zaka, zoopsa, ndi zina zambiri - madokotala ambiri am'maso amalimbikitsa kukayezetsa maso chaka chilichonse kapena ziwiri.

Nthawi imeneyo, ngati kuli kotheka, dokotala wanu adzakupatsani mankhwala oti mugwiritse ntchito pogula zovala. Izi zikuwoneka ngati zosokoneza mpaka mutadziwa tanthauzo la zilembo monga OS, OD, ndi CYL.

Kumbukirani kuti mankhwala omwe mumalandira chifukwa cha magalasi amaso siodalitsanso magalasi olumikizirana. Simungapeze mankhwala oti mugwirizane nawo mpaka dokotala atakuyesani moyenera ndikuwunika momwe maso anu akuyankhira pazovala zamagalasi.
