Bifocals kuthandiza pamaso

Wopitiriza chitukuko cha achipatala likuthandiza kuti anthu ambiri padziko lonse kuti ayambenso masomphenya awo otaika ndi kukhala ndi moyo wonse. Njira imodzi kutsimikiziridwa kuti achoke ku presbyopia, amene amapezeka ndi zaka anthu ambiri ndi ntchito awiriawiri awiri kapena kuposa a magalasi. Ndithudi, izi si nthawi yabwino, ndipo apa panadza kuthandiza bifocals, amene kuphatikiza katundu wa mitundu iwiri iwiri.

Childs, theka kumtunda kwa galasi mu magalasi awa mungathe kuona zinthu kutali, ndipo pansi - kusiyanitsa zinthu zimene pafupi. magalasi awa magalasi foni, ndiye bifocals akhale trifocals kapena ngakhale multifocal.

Lingaliro la chilengedwe anauziridwa ndi Mwachibadwa, anthu ena mitundu ya nsomba ndi Bifocal pamaso, amene amalola zabwino kuona zinthu pansi pa mosungiramo ndi pa nthawi yomweyo kutsatira njira ya Mbalame zodya nyama pamwamba. Akukhulupirira kuti bifocals woyamba anatulukira Bendzhamin Franklin, amene amaphatikizidwa ndi mitundu iwiri iwiri ya mandala mu chimodzi.

Chochitika chidwi pa mfundo imeneyi adafotokoza wasayansi ku Israel Zeev Zalewski, amene amaphatikiza galasi kuti magalasi bifocal savuta kwambiri kugwiritsa ntchito. magalasi ake sali malire kwakukulu pakati panes lapansi. Kuwala anasonyeza kuchokera kutali ndi pafupi zinthu lolunjika mu mtsinje umodzi mosalekeza, lomwe lili ndi diso lonse. Zimenezi zimathandiza mofanana zabwino kuona zinthu. Mu magalasi awa maso zochepa wotopa, ndipo ayenera kupatula nthawi kuti azolowere iwo.

chidwi Mbali tinaonera mayesero awo. Kunapezeka kuti iwo akhoza kusintha onse bwinobwino. Ndiko kuti, magalasi awa silingakhoze kokha kupirira m'badwo uno matenda ndi zothandiza kwambiri ngati muyeso njira.

Development matekinoloje mkulu amatipatsanso njira zina mu chitukuko cha nkhani ya zachilengedwe. Amene anakamba magalasi bifocal mu Baibulo wake amagetsi. Pankhaniyi, pakati pa panes awiri anaikapo mu nsalu yotchinga madzi Krustalo, amene amatipatsa fano.

Mu nkhani ya Baibulo amagetsi a bifocals kuti kutukula mavuto kuonjezera chithunzi khalidwe. Chidwi chatsopano zinthu ndi njira kuwonjezera kapena kuchepetsa fano, komanso autofocus. The prototypes woyamba ndi amene amapereka PixelOptics, amene anapitiriza kafukufuku wake m'dera limeneli.

Atakambilana adotolo anu, inu mukhoza kugula bifocals. mtengo imasiyana malingana mankhwala kampani ndi khalidwe la katundu. Koma chinthu chachikulu mu nkhani iyi, moyenerera osankhidwa magawo mfundo zimenezi. Pa izi zimatengera pa anatengera yomaliza ya nthawi zingatenge masiku khumi pambuyo chiyambi cha ntchito.

Ngati muli ndi nthawi yambiri yogwira ntchito ndi zinthu zimene ali pafupi, galasi pansi ayenera kukhala m'dera lalikulu kuposa chapamwamba. Ndipo moyenera, pamene ntchito ndi anthu akutali, kugula magalasi ndi malo wamkulu mawindo chapamwamba. Izi zidzakuthandizani mofulumira atengere mankhwala atsopano ndi kukhala ndi moyo wonse.
