Ndikofunikiradi Kusankha Magalasi Oyenera Owerengera

Kukalamba kwa anthu kwakhala kofala padziko lonse lapansi. Masiku ano, vuto la thanzi la okalamba limatengedwa mozama ndi aliyense. Pakati pawo, mavuto a masomphenya a thanzi la okalamba amafunikanso chisamaliro ndi chisamaliro cha aliyense. Anthu ambiri amaganiza kuti presbyopia satha kuwona bwino mawu apafupi, choncho ingogulani magalasi a presbyopic. M'malo mwake, kusankha magalasi owerengera sikuli "mwachisawawa". Ndikofunikira kusankha mosamala magalasi owerengera omwe amakuyenererani.

Momwe Mungasankhire Magalasi Owerengera

1.MASOMPHENYA AMODZI

Ndi njira yomwe imagwiritsidwa ntchito kwambiri kukonza presbyopia. Nthawi zambiri, pamaziko owonera bwino patali, kuchuluka kwa mphamvu zamagalasi zabwino kumawonjezeredwa, kotero kuti kuwona bwino patali kumamveka bwino pafupi.

Ubwino:Kuwala kwa magalasi omasuka, osasinthasintha mkati mwa masomphenya, osavuta kusintha; ndalama ndi zotsika mtengo.

Zoyipa:Kwa anthu ena amene amafunika kuvala magalasi kuti awonere patali, opaleshoniyo imakhala yovuta kwambiri. Mwachitsanzo, okalamba omwe ali ndi myopia yapakati mpaka pamwamba nthawi zambiri amafunika kuvala magalasi okhala ndi myopia yapamwamba poyenda ndi kuonera TV; ngati amawerenga mabuku kapena mafoni a m'manja, ayenera kusintha. Kuvala magalasi a presbyopic, kuwatsegula ndi kuwachotsa, ntchitoyo ndi yovuta. Pazimenezi, kodi pali magalasi omwe angathe kuthetsa vuto la kuona kutali ndi pafupi nthawi imodzi? Inde, bifocals.

2. Bifocals

Zimatanthawuza kukonzedwa kwa mphamvu ziwiri zosiyana zowonetsera pa magalasi omwewo kuti akhale magalasi owonetserako omwe ali ndi magawo awiri okonza nthawi imodzi.

Ubwino:Chosavuta, theka lakumtunda la mandala ndi malo owonera patali, ndipo theka lakumunsi ndi malo owonera pafupi. Magalasi amodzi amathetsa vuto la kuona kutali ndi pafupi, ndipo amapewa kunyamuka ndi kuvala magalasi awiri chammbuyo ndi mtsogolo.
Zoyipa:Kwa okalamba omwe ali ndi madigiri apamwamba a presbyopia, zinthu zomwe zili pamtunda wapakati sizingakhale zomveka bwino; Kutsika kwa prism kumapangitsa kuti chinthucho chiwoneke ngati "chikudumpha" kumalo apamwamba.
Poyerekeza ndi mandala a maso amodzi, mandala a bifocal amatha kuona kutali ndi pafupi, koma ndi osathandiza pang'ono pazinthu zapakati, ndiye kodi pali magalasi omwe amatha kuwona kutali, pakati ndi pafupi, ndipo amatha kuwona bwino pamtunda uliwonse? Inde, magalasi opita patsogolo.

3. Magalasi opita patsogolo

Zimatanthawuza kusintha kwapang'onopang'ono kwa magalasi osawerengeka owonjezera kuchokera pamwamba mpaka pansi pa chidutswa cha magalasi, kupatsa mwiniwake masomphenya osalekeza komanso omveka bwino kuchokera kutali mpaka pafupi, ndipo palibe magalasi amtundu wapadera malinga ndi maonekedwe a lens.

Ubwino:Zosavuta, pamwamba pa mandala ndi malo owonera patali, ndipo pansi ndi malo owonera pafupi. Pali malo aatali komanso opapatiza omwe amalumikiza ziwirizi, zomwe zimakulolani kuwona zinthu zapakatikati. Mbali ziwiri za dera la gradient ndi madera ozungulira. Magalasi awiri nthawi imodzi amathetsa zosowa zowoneka zakutali, zapakati ndi zakutali, kukwaniritsa "kusintha kwa liwiro lopanda masitepe".
Zoyipa:Poyerekeza ndi magalasi owonera amodzi, zimatenga nthawi yayitali kuti muphunzire ndi kuzolowera.

Kotero, kodi ndi "kamodzi kokha" kusankha magalasi oyenera owerengera?
Komanso sichoncho. Mlingo wa presbyopia udzapitilira kukula ndi zaka, nthawi zambiri kumawonjezeka pamlingo wa madigiri 50 pazaka 5 zilizonse. Kafukufuku wapeza kuti kwa anthu opanda diopter, digiri ya presbyopia ali ndi zaka 45 nthawi zambiri imakhala madigiri 100, ndipo imawonjezeka kufika madigiri 200 ali ndi zaka 55. Pa zaka 60, digiriyi idzawonjezeka kufika madigiri 250 mpaka 300. Mlingo wa presbyopia nthawi zambiri suzama. Koma pazochitika zenizeni, tikulimbikitsidwa kupita ku chipatala cha maso kuchipatala cha optometry musanayambe kuitanitsa magalasi
Ngati mukufuna kudziwa zambiri za mafashoni a magalasi komanso kufunsira kwamakampani, chonde pitani patsamba lathu ndikulumikizana nafe nthawi iliyonse.
