Tiyeni tiphunzire zambiri zokhudza maso. Kodi Masomphenya a 20/20 ndi chiyani?

Kodi munamvapo dokotala wa maso kapena dokotala wa maso akunena kuti, "Maso anu ndi 20/20" mukapita kukayezetsa maso? Kapena mwina munamvapo mnzanu akunena zimenezo. Anthu ambiri amaganiza kuti masomphenya a 20/20 ndi angwiro, angwiro, komanso angwiro. Koma kodi ndi zoonadi? Tiyeni tidziwe bwino lomwe nthano ya "20/20".

Kodi Masomphenya a 20/20 ndi chiyani?

Mwachidule, kuona kwa 20/20 ndi kuona "kwabwinobwino". Kumayesa momwe mungawonere bwino komanso molunjika chinthu chomwe chili pa mtunda wa mamita 20. Akatswiri a maso amati izi ndi kuwona bwino.

Tangoganizirani, mukapita kukayezetsa maso, amakupangitsani kuyang'ana tchati yokhala ndi zilembo. Muli pamtunda wa mamita 20 kuchokera pa tchati.

• Nambala yoyamba (20): Izi zimakuuzani kutalika komwe muli nako kuchokera pa tchati chokhala ndi zilembo. Mu mayeso a maso, nthawi zonse izi zimakhala 20, chifukwa mtunda wamba ndi mamita 20.
• Nambala yachiwiri (20 mbali inayo): Izi zikuwonetsani kuti munthu amene ali ndi maso abwinobwino angaone chinthu chomveka bwino komanso chakuthwa bwanji chomwe mungachione muli pa mtunda wa mamita 20.

Ndiko kuti, ngati muli ndi masomphenya a 20/20, zomwe mumawona muli pamtunda wa mamita 20, munthu amene ali ndi masomphenya abwinobwino amatha kuwona bwino lomwe ali pamtunda wa mamita 20. Awa ndi masomphenya "abwinobwino", osati "angwiro". Chodabwitsa n'chakuti, pafupifupi 35% yokha ya anthu padziko lonse lapansi ali ndi masomphenya a 20/20, kaya amavala magalasi, magalasi olumikizirana, kapena adachitidwa opaleshoni ya maso.

Tsopano, onani, nthawi zina masomphenya anu angatchulidwe kuti 20/15. Izi zikutanthauza kuti chinthu chomwe mungachione muli pa mtunda wa mamita 20 chiyenera kukhala pa mtunda wa mamita 15 kuti munthu amene ali ndi masomphenya abwinobwino aone bwino. Izi zikutanthauza kuti masomphenya anu ndi abwino kuposa apakati!

Komanso, ngati masomphenya anu ali 20/40, zikutanthauza kuti chinthu chomwe mungachione muli mtunda wa mamita 20 chikhoza kuoneka bwino ndi munthu amene ali ndi masomphenya abwinobwino ali mtunda wa mamita 40. Izi zikutanthauza kuti masomphenya anu ali pansi pang'ono pa avareji, chifukwa muyenera kukhala pafupi ndi masomphenyawo kuposa munthu wamba kuti muwaone bwino. Koma musadandaule, ngati masomphenya anu ali pansi pa 20/20, pali njira zambiri zokuthandizani kuwachotsa.

Monga momwe dziko lathu limayezera mtunda ndi mapazi, mayiko ena padziko lonse lapansi amagwiritsa ntchito njira yoyezera. M'mayiko amenewo, masomphenya a 20/20 amatchedwa masomphenya a 6/6. Izi zikutanthauza kuti, amayesa ngati mungathe kuwona bwino chinthu chomwe chili pamtunda wa mamita 6 m'malo mwa mapazi 20.

Kodi masomphenya a 20/20 ndiye chinthu chokhacho chofunikira pa masomphenya?

Ngakhale kuti n'kofunika kukhala ndi masomphenya a 20/20 kuti muwone dziko bwino, palinso zinthu zina zofunika kwambiri pa masomphenya.

• Kuwona mitundu: Kutha kuzindikira mitundu molondola.
• Kulinganiza maso: Izi ndizofunikira kwambiri pakuwona mozama komanso kuwona zinthu mu 3D. Zimafuna kuti maso onse awiri agwire ntchito limodzi bwino.
• Kuona pang'ono kapena usiku: Kuona pang'ono mumdima.
• Kuwona mbali zonse: Kuwona mbali zonse ziwiri komwe kungawonekere mbali zonse popanda kutembenuza mutu.

Kodi mukumvetsa? 20/20 ndi mbali imodzi yokha ya masomphenya. Zonsezi zimathandiza kuti masomphenya akhale abwino.

N’chifukwa chiyani kukhala ndi maso abwino n’kofunika kwambiri?

Kuona bwino ndikofunikira kuti mukhale otetezeka. Tangoganizirani, kuona galimoto pamsewu, kusaphonya sitepe iliyonse mukatsika masitepe, zonsezi zimafuna kuona bwino.

Komanso, kuona bwino n'kofunika kwambiri kuti mukhale ndi moyo wabwino . Kuona kwanu kumakhudza ntchito yanu, zochita zanu zachikhalidwe, zosangalatsa zanu, kuwerenga buku, zonsezi. Kuona bwino kungatanthauze kuti mumavala magalasi kapena magalasi olumikizirana. Chofunika kwambiri ndichakuti muzitha kuona bwino momwe mungathere kuti mugwirizane ndi chilengedwe ndi anthu omwe akuzungulirani - kaya ndi kukonza kapena ayi.

Kuona bwino si kungopewa kungoyang'ana m'makona akuthwa. Kumathandizanso kuti maganizo anu akhale anzeru , kukupatsani mphamvu zogwirira ntchito zanu za tsiku ndi tsiku. Kuwerenga njira yophikira pamene mukuphika, kuwerenga malangizo pa botolo la mankhwala, kuwerenga machenjezo pa yankho loyeretsera, ndi kuona zizindikiro za pamsewu ndi manambala a njira za basi pamene mukuyendetsa galimoto kumafuna masomphenya abwino.

Kodi mungadziwe bwanji ngati muli ndi masomphenya a 20/20?

Dokotala wa maso adzayesa maso anu ndi mayeso a maso. Nthawi zambiri amagwiritsa ntchito njira zingapo, zazikulu zomwe ndi:

• Mayeso a kuwona bwino: Iyi ndi yomwe ndatchula kale, komwe muyenera kuwerenga zilembo pa tchati. Tchati iyi imatchedwa tchati cha Snellen . Nthawi zina, m'malo mwa zilembo, matchati okhala ndi mawonekedwe amagwiritsidwanso ntchito, makamaka kwa ana aang'ono.
• Retinoscopy: Izi zimaphatikizapo kugwira magalasi osiyanasiyana m'diso lanu kuti muwone lomwe limakupatsani mwayi wowona bwino. Dokotala amachita izi akuwunikira diso lanu.
• Kusinthasintha kwa Magazi: Izi zikutanthauza kuti mukuyang'ana makina (mwina chithunzi cha nyumba m'munda, kapena baluni yotentha kumapeto kwa msewu wautali). Makinawo amayesa masomphenya anu okha. Dokotala amagwiritsa ntchito ziwerengerozi kuti apitirize kuwunika masomphenya anu ndikukupatsani magalasi oyenera.

Kodi ndi zifukwa ziti zomwe sindingathe kuona bwino nthawi zonse?

Zomwe zimayambitsa masomphenya ochepera 20/20 ndi zolakwika za refractive. Izi ndi kusintha kwa mawonekedwe a diso lanu komwe kumayambitsa kusawona bwino. Izi zikuphatikizapo:

• Kuona Zinthu Patsogolo Kwambiri: Mkhalidwe umene zinthu zapafupi zimaoneka zosawoneka bwino, ndipo nthawi zina zinthu zakutali zimakhala zosawoneka bwino pang'ono.
• Myopia kapena Near Viewness: Matenda omwe zinthu zakutali zimakhala zosawoneka bwino ndipo zinthu zapafupi zimaonekera bwino.
• Presbyopia: Imeneyi ndi vuto lomwe limachitika munthu akamakalamba. Limapangitsa kuti zikhale zovuta kuwerenga pafupi ndi zinthu monga mabuku ndi manyuzipepala. Nthawi zambiri limayamba munthu akakwanitsa zaka 40.
• Astigmatism: Pa vutoli, chifukwa diso silili lozungulira bwino, kuwala sikulunjika pamalo omwewo mkati mwa diso. Zotsatira zake, zinthu zapafupi ndi zakutali zingawoneke ngati zopotoka pang'ono komanso zosawoneka bwino.

Kuwonjezera pa zolakwika izi zoyang'ana maso, matenda ena a maso angakhudzenso maso anu. Zitsanzo zina ndi izi:

• Ma cataracts: Kuphimba kwa lens ya diso.
• Matenda a cornea: Matenda omwe amapezeka mu cornea, nembanemba yowonekera kutsogolo kwa diso.
• Matenda a shuga: Kuwonongeka kwa retina kumbuyo kwa diso komwe kumachitika chifukwa cha matenda a shuga.
• Glaucoma: Kuwonongeka kwa mitsempha ya maso chifukwa cha kupanikizika kwambiri mkati mwa diso.
• Matenda a retinal: Matenda osiyanasiyana omwe amapezeka mu retina ya diso.
• Matenda monga strabismus , mwachitsanzo , amblyopia/diso laulesi.

Komanso, n'zotheka kukhala ndi maso abwino kuposa achizolowezi, koma ndi ochepa pang'ono.

Kodi vuto la kuchepa kwa maso limachiritsidwa bwanji?

Ngati muli ndi zolakwika za refractive, pali njira zambiri zochiritsira zomwe zingakuthandizeni kukonza masomphenya anu. Njirazi zikufuna kuti masomphenya anu akhale pafupi ndi 20/20 momwe mungathere. Izi zikuphatikizapo:

• Magalasi: Iyi ndiyo njira yodziwika bwino komanso yosavuta.
• Magalasi olumikizana: Njira ina yabwino kwa iwo omwe sakonda magalasi.
• Opaleshoni yokonza maso: Zinthu monga opaleshoni ya laser zimatha kusintha masomphenya kwamuyaya.

Ngati muli ndi matenda ena a maso, angafunike opaleshoni kapena chithandizo chamankhwala. Kuphatikiza apo, mungafunike kuvala magalasi kapena magalasi olumikizirana. Ngakhale zili choncho, nthawi zina simungafikire masomphenya a 20/20, koma muthabe kukhala ndi masomphenya omwe angakhale omasuka kwa inu.

Kodi ndingachepetse chiopsezo cha kuwona kwanga pansi pa 20/20?

Inde, ndithudi. Pali zinthu zambiri zomwe mungachite kuti maso anu akhale athanzi komanso kuchepetsa chiopsezo chanu chokhala ndi vuto la kuwona. Izi zikuphatikizapo:
