Mayeso a Visual Acuity

Kodi Mayeso a Visual Acuity ndi chiyani?

Mayeso a Visual Acuity Test ndi njira yosavuta koma yofunikira yomwe imagwiritsidwa ntchito poyesa kuthwa kapena kumveka bwino kwa masomphenya a munthu. Zimathandizira akatswiri osamalira maso kumvetsetsa momwe mumawonera zinthu patali. Mayesowa ndi amodzi mwa njira zoyambira pakuwunika kwa diso ndipo ndikofunikira kuti azindikire zovuta za masomphenya monga kuwonera pafupi, kuyang'ana patali, kapena zolakwika zina zowonera.

Tchati cha Snellen

Tchati cha Snellen ndiye chida chomwe chimagwiritsidwa ntchito kwambiri poyesa kuona bwino. Lili ndi mizere 11 ya zilembo, kuyambira wamkulu kwambiri pamwamba ndikucheperachepera. Zilembozi zimasankhidwa kuti ziziimira kukula kwake komwe anthu ambiri omwe ali ndi masomphenya abwino ayenera kuwona patali.

Zotsatira za mayesowa zimawonetsedwa ndi kagawo kakang'ono monga 20/20, 20/40, kapena 20/200. Kagawo kakang'ono kameneka kamasonyeza luso lanu la maso poyerekezera ndi zimene munthu amene ali ndi masomphenya abwino amatha kuona ali patali.

• 20/20 masomphenya: Izi zikutanthauza kuti mutha kuwona pamapazi a 20 zomwe munthu yemwe ali ndi masomphenya abwino amatha kuwona pamapazi 20. Amaonedwa ngati masomphenya "wachibadwa".
• 20/40 masomphenya: Izi zikutanthauza kuti mutha kuwona pamtunda wa 20 zomwe munthu yemwe ali ndi masomphenya abwino amatha kuwona pamapazi 40.
• 20/200 masomphenya: Izi zimatchedwa kusawona kwalamulo ku United States. Zikutanthauza kuti mutha kuwona pamapazi a 20 zomwe munthu yemwe ali ndi masomphenya abwino amatha kuwona pamapazi a 200.

Momwe Visual Acuity Test imagwirira ntchito

Panthawi ya Visual Acuity Test, njira zotsatirazi zimatsatiridwa:

• Kuyika: Mudzafunsidwa kuti mukhale patali kuchokera pa tchati cha Snellen (nthawi zambiri mapazi 20).
• Phimbani Diso Limodzi: Mudzalangizidwa kuphimba diso limodzi ndi chigamba kapena dzanja lanu.
• Kuwerenga Tchati: Mudzafunsidwa kuti muwerenge mzere wawung'ono kwambiri wa zilembo zomwe mungawone, kuyambira pamwamba pa tchati ndikutsika pansi.
• Sinthani Maso: Pambuyo powerenga tchati ndi diso limodzi, ndondomekoyi imabwerezedwa ndi diso lina.
• Results: Mzere waung'ono kwambiri womwe mungawerenge ndi diso lililonse umagwiritsidwa ntchito kuti muwone bwino.

Kugwiritsa Ntchito Mayeso a Visual Acuity

Mayeso a Visual Acuity ali ndi ntchito zingapo m'munda wa optometry ndi ophthalmology, ndipo amatenga gawo lofunikira pakuzindikira ndikuwongolera mavuto osiyanasiyana owonera. Nayi ntchito zoyambira:

1. Kuzindikira Mavuto a Masomphenya

Kuyesako kumagwiritsidwa ntchito kuzindikira zolakwika za refractive monga:

• Kuwona pafupi (Myopia): Mkhalidwe womwe umatha kuwona zinthu zoyandikira bwino koma osawona zinthu zakutali.
• Kuwona Patsogolo (Hyperopia): Mkhalidwe woti mutha kuwona zinthu zakutali bwino koma mukuvutikira kuwona zinthu zapafupi.
• Astigmatism: Matenda omwe amayamba chifukwa cha diso losaoneka bwino lomwe limapangitsa kuti munthu asaone bwino patali.
• Presbyopia: Kuvuta kwa zaka zakubadwa pakuwona zinthu zapafupi chifukwa cha kuchepa kwa kuthekera kwa diso kuyang'ana.

2. Kuwunika Thanzi la Maso

Mayesero owoneka bwino amathandizira kuyang'anira thanzi la maso pakapita nthawi, kuzindikira kusintha kulikonse kwa masomphenya. Izi ndizofunikira makamaka kwa anthu omwe ali ndi matenda monga glaucoma, ng'ala, kapena macular degeneration, kumene masomphenya amatha kuwonongeka pang'onopang'ono.

3. Kuyang'ana Kufunika kwa Magalasi Owongolera

Kuyezetsako kumathandiza optometrist kudziwa ngati mukufuna magalasi kapena ma lens. Imayesa momwe maso anu amawonera zinthu zakutali ndikuthandizira kukupatsani magalasi olondola kuti muwone bwino.

4. Kuzindikira Kuwonongeka kwa Masomphenya pa Zolinga Zalamulo

M'mayiko ambiri, zotsatira za kusawona bwino zimagwiritsidwa ntchito pofuna kudziwa ngati wina ali woyenerera kukhala wakhungu. Mwachitsanzo, ku United States, masomphenya a 20/200 amaonedwa ngati poyambira kusawona kwalamulo.

5. Mayeso a Pre-Employment kapena Licensing

Ntchito zina, monga kuyendetsa, kuyendetsa ndege, kapena kugwira ntchito zina, zimafuna kuti anthu apambane mayeso owonetsetsa kuti akwaniritsa zofunikira pachitetezo ndi magwiridwe antchito.

Normal Range kwa Visual Acuity

Kuwoneka bwino kumayesedwa pogwiritsa ntchito kachigawo kakang'ono (mwachitsanzo, 20/20 kapena 20/40). Izi ndi zomwe gawo lililonse limatanthauza:

• 20/20 Masomphenya: Izi zimatengedwa ngati masomphenya "wamba". Munthu yemwe ali ndi masomphenya 20/20 amatha kuona bwino chinthu chomwe chili pamtunda wa 20, zomwe ndizomwe zimayembekezereka kwa munthu amene ali ndi maso athanzi.
• 20/40 Masomphenya: Ngati muli ndi masomphenya a 20/40, mukhoza kuona pa mapazi 20 zomwe munthu yemwe ali ndi masomphenya abwino amatha kuona kuchokera ku 40 mapazi. Izi zimatengedwa ngati vuto laling'ono.
• 20/200 Masomphenya: Uwu ndi mwayi wakhungu mwalamulo m'maiko ambiri. Munthu yemwe ali ndi masomphenya 20/200 amatha kuona pamtunda wa mapazi 20 zomwe munthu yemwe ali ndi masomphenya abwino amatha kuona kuchokera ku mapazi 200.

Zotsatira Zina:

• 20/15 Masomphenya: Izi ndizabwinoko kuposa masomphenya wamba, kutanthauza kuti mutha kuwona zinthu pamtunda wa 20 zomwe ena angafunikire kukhala pamapazi 15 kuti muwone.
• 20/40 Masomphenya kapena oipitsitsa: Izi zitha kuwonetsa kufunikira kwa magalasi owongolera kapena kuunikanso kwina kuti muzindikire zovuta zathanzi lamaso.

Momwe Mungakonzekerere Mayeso a Visual Acuity

Mayeso a Visual Acuity ndi osavuta, ofulumira, komanso osasokoneza. Komabe, pali njira zingapo zomwe mungatenge pokonzekera mayeso kuti muwonetsetse zotsatira zolondola:

1. Onetsetsani Kuti Mwapuma Bwino: Ngati mukumva kutopa, zitha kusokoneza luso lanu loyang'ana bwino panthawi ya mayeso. Onetsetsani kuti mwapuma bwino mayeso anu asanakwane kuti mukwaniritse zotsatira zabwino kwambiri.
2. Pewani Kuvala Ma Contacts Asanayesedwe: Ngati mumavala ma contact lens, tikulimbikitsidwa kuti muwachotse musanayambe kuyezetsa, makamaka ngati mukuyenera kulandira mankhwala atsopano. Ma lens olumikizana nawo nthawi zina amatha kukhudza kulondola kwa mayeso ngati sakuyikidwa bwino.
3. Pewani Kudontha Kwa Maso kapena Mankhwala Ena: Mankhwala ena a maso, makamaka omwe amagwiritsidwa ntchito pochiza matenda ngati maso owuma, amatha kukhudza masomphenya anu. Onetsetsani kuti mwakambirana za mankhwala omwe mukugwiritsa ntchito ndi dokotala musanayesedwe.
4. Bweretsani Mndandanda wa Mankhwala: Ngati mukulandira chithandizo cha matenda aliwonse a maso kapena zovuta zina zathanzi zomwe zingakhudze masomphenya anu, ndizothandiza kubweretsa mndandanda wamankhwala omwe mwakumana nawo.
5. Khalani Okonzeka Kukambilana Zizindikiro: Ngati mukukumana ndi kusintha kulikonse m'masomphenya, monga kuvutika kuwona mopepuka, kusawona bwino, kapena kuwerenga movutikira, onetsetsani kuti mwatchula zizindikiro izi kwa wothandizira maso.

Kutanthauzira kwa Zotsatira za Mayeso

Zotsatira za mayeso a acuity acuity zidzafotokozedwa ngati kachigawo kakang'ono, ndi nambala (nambala yapamwamba) yosonyeza mtunda umene mungathe kuwona zilembo, ndi denominator (nambala yapansi) yosonyeza mtunda umene munthu amene ali ndi masomphenya amatha kuwerenga. makalata omwewo.

Zotsatira Zachitsanzo:

• 20/20 Masomphenya: Palibe cholakwika cha refractive, mutha kuwona bwino pamamita 20.
• 20/40 Masomphenya: Kulakwitsa kocheperako, kungafunike magalasi owongolera.
• 20/200 Masomphenya: Kusawona mwalamulo, kungafunike thandizo lachipatala kapena zothandizira masomphenya.

Ngati zotsatira zanu zikuwonetsa kufunikira kwa magalasi kapena ma lens, katswiri wosamalira maso adzakuthandizani kudziwa mankhwala oyenera.
