Mukakwanitsa zaka 40, kodi zakhala zovuta pang'ono kuti muwerenge nyuzipepala kapena uthenga pafoni yanu? Kodi mwakhala mukusuntha dzanja lanu patsogolo pang'ono chifukwa zilembozo zikuwoneka zosamveka bwino? Izi ndi zomwe zimachitika kwa anthu ambiri. Koma mukamavala magalasi kuti muwone pafupi, muyenera kuwachotsa mukawona patali. Kusintha magalasi awa ndi vuto lalikulu kwa anthu ena. Ndiye, kodi mwamvapo za ukadaulo wotchedwa 'Monovision' womwe umabwera ngati yankho labwino pa izi? Tiyeni tikambirane lero.
Mwachidule, kodi monovision ndi chiyani?
Ndi zophweka kwambiri. Monovision ndi njira yophunzitsira maso anu kuyang'ana zinthu zomwe zili pafupi nanu (monga kuwerenga buku, kuyang'ana foni yanu) ndi diso lanu lina kuyang'ana zinthu zomwe zili kutali (monga kuyendetsa galimoto, kuonera TV) . Zili ngati kupatsa maso anu ntchito ziwiri zosiyana.
Taganizirani izi motere. Diso lanu limodzi ndi labwino kwambiri poona pafupi, ndipo diso lina ndi labwino kwambiri poona patali. Ubongo wanu umaphatikiza zithunzi kuchokera m'maso awiriwa, ndikupanga chithunzi chathunthu chomwe chimakupatsani mwayi wowona pafupi komanso kutali bwino. Anthu ena amatcha izi 'masomphenya osakanikirana'. Izi zikutanthauza kuti mutha kuchotsa kwathunthu kufunikira kwa magalasi kuti muwone pafupi.
N’chifukwa chiyani tifunikira chinthu chonga ichi?
Pamene tonse timakalamba, nthawi zambiri titakwanitsa zaka 40, zimakhala zovuta kuona zinthu pafupi. Mwina mwawonapo okalamba akusuzumira maso pamene akuwerenga nyuzipepala. Mu zamankhwala, vutoli timalitcha 'presbyopia' .
Izi zili choncho chifukwa kusinthasintha kwa lenzi mkati mwa maso athu kumachepa ndi ukalamba. Minofu yaying'ono mkati mwa diso ('minofu ya ciliary') singathe kupindika lenzi iyi ngati pakufunika kuti iyang'ane pa chinthu chapafupi. Izi zimatchedwa 'Accommodation reflex' yomwe imafooka.
Monovision imapewa njira yofookayi. Komanso, anthu omwe amachitidwa opaleshoni ya cataract m'diso limodzi nthawi zina amatha kuikidwa lenzi ndi monovision system iyi.
Kodi njira zopezera monovision ndi ziti?
Pali njira zingapo zomwe mungakwaniritsire monovision iyi. Zina ndi zakanthawi, zina ndi zachikhalire.
- Ma Lens Olumikizana: Iyi ndi njira yabwino komanso yotetezeka yodziwira ngati monovision ndi yoyenera kwa inu. Dokotala wanu adzayika lens yowonera pafupi m'diso limodzi ndi lens yowonera kutali m'diso lina kwa kanthawi. Ino ndi nthawi yabwino yodziwira ngati mungazolowere komanso ngati muli ndi vuto lililonse.
- Kukonza Masomphenya a Laser: Ngati mukuona kuti njira iyi ikugwira ntchito bwino ndi ma contact lenses, LASIK kapena PRK ikhoza kukhala yankho lokhazikika.Mungathe kuchitidwa opaleshoni ya laser motere. Izi zimasintha mawonekedwe a cornea ya diso ndipo zimapangitsa kuti diso liziona bwino nthawi zonse.
- Opaleshoni ya Lens ya M'maso: Pa opaleshoni ya cataract, lens yopangira yomwe imayikidwa mkati mwa diso ikhoza kusinthidwa kuti igwiritsidwe ntchito ngati monovision.
Chofunika kwambiri ndikuyesera nthawi zonse ndi ma contact lenses kuti muwone momwe monovision system ikugwirizanirani musanachite opaleshoni yokhazikika.
Kodi ubwino ndi kuipa kwa njira iyi ndi kotani?
Monga chithandizo chilichonse chamankhwala, monovision ili ndi ubwino ndi kuipa kwake. Tiyeni tiwone zomwe zili.
| Ubwino | Zoyipa |
|---|---|
| Kudalira magalasi kuti munthu aone pafupi kumachepa kwambiri. | Anthu ena amavutika kuzolowera kaonedwe katsopano aka. Angamve chizungulire komanso kusokonezeka maganizo. |
| Mungayesere kugwiritsa ntchito ma contact lens musanayambe opaleshoni yokhazikika. | Popeza maso onse awiri sagwira ntchito limodzi, kuwona kwa 3D ndi kuzindikira kwakuya kungachepe pang'ono. |
| Magalasi olumikizirana angagwiritsidwe ntchito ngati njira ina kwa iwo omwe akuopa kapena osasangalala ndi opaleshoni. | Kuona bwino kumatha kukhala kopanda kuwala kwenikweni m'malo opanda kuwala kwenikweni, makamaka usiku. |
| Ntchito zambiri za tsiku ndi tsiku zitha kuchitika popanda magalasi. | Mkhalidwe woopsa wotchedwa 'Pulfrich effect' ungachitike. |
Kodi 'Pulfrich Effect' yoopsa iyi ndi iti?
Ichi ndi chinthu choyenera kusamala nacho. Mwachidule, chifukwa zithunzi zomwe zimachokera m'maso mwanu kupita ku ubongo wanu zimamveka bwino zimasiyana, nthawi yomwe ubongo wanu umatenga kuti zithunzi ziwirizi zigwiritsidwe ntchito ndi yosiyana pang'ono. Chithunzi chochokera m'diso limodzi chimafika mu ubongo wanu pang'ono kwambiri kuposa sekondi ina.
Kusiyana kochepa kumeneku kumapangitsa kuti zikhale zosatheka kumvetsetsa bwino mtunda, liwiro, ndi komwe chinthu chikuyenda.
Tangoganizirani kuti mukuyendetsa galimoto. Kodi zingakhale zoopsa bwanji ngati simungadziwe bwino mtunda womwe uli pakati panu ndi galimoto kapena munthu amene akuwoloka msewu patsogolo panu? Izi zitha kuonekera kwambiri mukayendetsa galimoto mothamanga kwambiri komanso mukakhala ndi kuwala kochepa .
Choncho, ngati ndinu munthu amene mumayendetsa galimoto pafupipafupi, muyenera kulankhula ndi dokotala wanu za izi musanasankhe galimoto yoyendera galimoto.
Zinthu zoti muganizire mukakhala ndi monovision
Mukazolowera monovision, ndikofunikira kwambiri kusamalira thanzi la maso anu.
- Yesani maso anu nthawi zonse: Yesani maso anu kamodzi pachaka kapena ziwiri, monga momwe dokotala wanu wa maso akulangizirani. Ngati muli ndi matenda ena, monga matenda a shuga , mungafunike kuwayesa pafupipafupi.
- Magalasi apadera: Dokotala wanu angakulembereni magalasi apadera kuti mugwiritse ntchito poyendetsa galimoto usiku kapena pazinthu zovuta kwambiri, monga kugwira ntchito pa kompyuta. Izi zidzakuthandizani kuti mukhale ndi masomphenya abwino kwambiri panthawi yovutayi.
Monovision ndi njira yabwino yothandizira anthu ambiri omwe ali ndi vuto la kuwona pafupi kuchotsa magalasi. Koma si kwa aliyense. Kaya mungazolowere komanso ngati imayambitsa zotsatirapo zake zimasiyana malinga ndi munthu.
Uthenga Wopita Nawo Kunyumba
- Monovision ndi njira yophunzitsira diso limodzi kuti liwone pafupi ndi linalo kuti lione patali. Iyi ndi njira yabwino yothetsera vuto la presbyopia lomwe limachitika ndi ukalamba.
- Njira iyi si yoyenera aliyense, choncho musanachite opaleshoni yokhazikika, onetsetsani kuti mwayiyesa ndi ma contact lens.
- Ngati mumayendetsa galimoto pafupipafupi, lankhulani ndi dokotala wa maso anu za chiopsezo cha 'Pulfrich effect'.
- Galasi losiyana lingafunike pazochitika zina zapadera (monga kuyendetsa galimoto).
- Ndikofunikira kwambiri kufunsa upangiri kwa dokotala wa maso wodziwa bwino ntchito kuti musankhe njira yochiritsira yomwe ili yoyenera kwa inu.
