Mugihe tugenda dusaza, lens, sisitemu yibanda kumaso yacu, itangira gukomera buhoro buhoro no gutakaza ubuhanga bwayo, kandi imbaraga zayo zo guhinduka zitangira gucika intege buhoro buhoro, biganisha kubintu bisanzwe bya fiyologiki: presbyopiya.Niba ingingo yegereye irenze santimetero 30, kandi ibintu ntibishobora kugaragara neza muri santimetero 30, kandi ugomba gukenera kure kugirango ubone neza, ugomba gutekereza kwambara ibirahuri bya presbyopique.
Iki gihe twiga kubyerekeye ibirahuri bigenda bitera imbere muri presbyopia optique.Iyo presbyopia ibaye, birarambiranye cyane kubona, kuko ijisho ryumuntu rimeze neza mugihe ureba kure, kandi birasabwa kwibanda kuri macro iyo ureba hafi.Nyamara, imbaraga zo guhindura lens ya presbyopic zifite intege nke, kandi intumbero ntabwo ikomeye bihagije iyo urebye hafi, bizongera umutwaro kumaso., ibimenyetso nko kubabara amaso, kutabona neza, no kubabara umutwe nibimenyetso bisanzwe.
Ihame ryimikorere myinshi
Igishushanyo mbonera cyibice byinshi ni ugukora ibintu byinshi bikomeza kure, hagati kandi hafi yibintu byibanda kumurongo umwe.Mubisanzwe, igice cyo hejuru cyinzira nigikoresho cyo gukurura kure, igice cyo hepfo ni hafi yingufu zogucika intege, naho igice cyo hagati ni agace gahoro gahoro gahoro gahoro gahoro gahoro.Hagati ya optique ya linzira nyinshi ni mm 10-16 munsi yikigo cya optique na mm 2-2.5 mumazuru.Twabibutsa ko hari uduce twa aberration kumpande zombi za zone igenda itera imbere.Iyo umurongo wo kureba wimukiye muri kariya gace, ikintu kigaragara kizahinduka, bigatuma bigorana kandi ntibyoroshye kubona.
Nigute ushobora gukoresha amajyambere menshi
Intambwe igenda itera intambwe igenda yongerera imbaraga kuva hejuru kugeza hasi, kandi igatanga ibice bitatu byihishe byiterambere, bikubiyemo kure, hagati, hamwe no kureba kure, byerekana neza ahantu hatandukanye.Iyo wambaye ibirahuri bigenda bitera imbere kunshuro yambere, umurima wo kureba kumpande zombi za lens urashobora kugororwa no kugoreka.Iyo ikadiri yimyanya yimutse cyangwa ihindagurika, irashobora kandi gutera ikibazo no kutabona neza.Kurikiza intambwe zo "guceceka mbere hanyuma wimuke, ubanze imbere hanyuma hanyuma hanze" kugirango witoze buhoro buhoro.
01. Agace ka terefone
Mugihe utwaye cyangwa ureba, shyira umusaya imbere imbere, komeza umutwe wawe utambitse, kandi urebe hagati yinzira ndende hejuru.
02. Agace kerekana intera ndende
Mugihe utwaye cyangwa ureba, shyira umusaya imbere imbere, komeza umutwe wawe utambitse, kandi urebe hagati yinzira ndende hejuru.Urashobora kwimura ijosi hejuru no hepfo kugeza ishusho isobanutse.
03. Gufunga ahantu hagaragara
Mugihe usoma igitabo cyangwa ikinyamakuru, shyira imbere yawe, uzamure umusaya imbere gato, hanyuma uhindure amaso yawe hepfo ahabigenewe.
04. Ahantu h'indorerwamo
Hariho uduce kumpande zombi za lens aho umucyo uhinduka, kandi umurima wicyerekezo uzaba utagaragara.Nibisanzwe.
05. Ibyifuzo:
Kuzamuka hejuru no kumanuka: Hasi umutwe wawe gato hanyuma urebe hasi, hanyuma uhindure amaso yawe uhereye hafi yindorerwamo yegereye hagati cyangwa indorerwamo ndende.
Kugenda buri munsi: Niba ubona bigoye kwibanda, gerageza urebe metero imwe imbere kugirango uhindure icyerekezo.Nyamuneka manura umutwe gato iyo ureba hafi.
Imashini zitwara cyangwa zikoresha: Niba ukeneye kureba kure kugera hafi, kuruhande cyangwa kuruhande rumwe mugihe ukora, nyamuneka ubikore nyuma yuko umenyereye rwose lens igenda itera imbere.
