Zomwe Muyenera Kudziwa Zokhudza Interpupillary Distance!

Kodi magalasi angatchulidwe bwanji kuti ndi oyenerera? Sikuti payenera kukhala diopter yolondola, iyeneranso kukonzedwa molingana ndi mtunda wolondola wa interpupillary. Ngati pali cholakwika chachikulu pamtunda wa interpupillary, wovalayo sangamve bwino ngakhale diopter ili yolondola. Ndiye n'chifukwa chiyani mtunda wolakwika wa interpupillary umapangitsa kuvala movutikira? Ndi funso ili, tiyeni tikambirane za chidziwitso cha interpupillary mtunda.

• Kodi mtunda wa interpupillary ndi chiyani?

Mtunda pakati pa malo geometric a ana a maso onse amatchedwa interpupillary mtunda. M'mawu optometry, chidule chake ndi PD, ndipo unit ndi mm. Pokhapokha pamene mzere wa maso onse awiri ukhoza kudutsa pakati pa kuwala kwa magalasi a magalasi ndi pamene amatha kuvala bwino. Choncho, pokonza magalasi, muyenera kuyesetsa kupanga kuwala pakati mtunda wa magalasi pafupi ndi interpupillary mtunda wa maso.

• Gulu la mtunda wa interpupillary?

Chifukwa diso la munthu limayang’ana m’kati mwa mtunda wosiyanasiyana. Pamene chinthucho chimayang'anitsitsa, maso amasokonekera kwambiri mkati. Chifukwa chake, kutengera mtunda woyang'ana, mtunda wa interpupillary umagawika pafupifupi mtunda wakutali komanso pafupi ndi interpupillary mtunda. Mtunda wa interpupillary umagwiritsidwa ntchito ngati magalasi poyang'ana patali; mtunda wapafupi wa interpupillary umagwiritsidwa ntchito ngati magalasi apafupi, omwe amadziwikanso kuti magalasi amaluwa.

• Kodi njira zoyezera mtunda wa interpupillary ndi ziti?

Mu optometry, zida monga pupillary distance rule, pupillary distance mita, ndi kompyuta refractor nthawi zambiri amagwiritsidwa ntchito poyeza. Potengera njira yomwe imagwiritsidwa ntchito kwambiri ndi interpupillary distance rule monga chitsanzo, ndikuwonetsa mwachidule njira yoyezera mtunda wa interpupillary:

1. Dokotala wa maso ndi womuyankhayo amakhala motalikirana ndi 40cm motalikirana.

2. Ikani interpupillary mtunda wolamulira mopingasa kutsogolo kwa mlatho wa mphuno ya phunziro ndi pa mtunda wofanana ndi mtunda wa pakati pa magalasi a maso. Osaipendekera mopingasa.

3. Wophunzirayo ayang'ane diso lakumanzere la dokotala wamaso ndi maso onse awiri.

4. Dokotala wamaso amatseka diso lake lakumanja ndikuyang'ana ndi diso lake lakumanzere kuti chizindikiro 0 cha interpupillary sikelo chikhale chopendekera mkati mwa diso lakumanja la wophunzirayo.

5. Sungani malo a interpupillary mtunda wolamulira mosasinthika, mutuwo amayang'ana diso lakumanja la optometrist ndi maso onse, ndipo optometrist amatseka diso lakumanzere, ndikuyang'ana ndi diso lakumanja. Sikelo yomwe wolamulira wa mtunda wa interpupillary amalumikizana ndi m'mphepete mwakunja kwa diso lamanzere la wophunzirayo ndi Kuyeza mtunda wa interpupillary patali.

• N'chifukwa chiyani kulakwitsa kwa interpupillary mtunda pa kukonza magalasi kumayambitsa kusapeza bwino?

Titamvetsetsa mfundo zomveka bwino za mtunda wa interpupillary, tiyeni tibwerere ku funso loyambalo. Chifukwa chiyani mtunda wolakwika wa interpupillary umapangitsa kuvala kusapeza bwino?

Ma lens awiri akakonzedwa, cholakwika chimachitika pamtunda wa interpupillary, kotero payenera kukhala diso limodzi (kapena awiri) pomwe kuwala kolandilidwa ndi mawonekedwe owonera sikungadutse pakati pa magalasi. Panthawiyi, chifukwa cha prism zotsatira za lens, njira ya kuwala yolowera m'diso imasinthidwa, ndipo zithunzi za chinthu chomwe chimapangidwa m'maso awiri sichigwera pazigawo zofanana, zomwe zimapangitsa kuti pakhale masomphenya awiri (ghosting). Zotsatira zake, ubongo nthawi yomweyo umatulutsa reflex yowongolera kusintha minofu ya extraocular ndikuchotsa diplopia. Ngati kuwongolera uku kupitilira, kumapangitsa kuti wovalayo asamve bwino, ndipo cholakwacho chikakulirakulira, chimakhala chosapiririka.

Ngati mukufuna kudziwa zambiri za mafashoni a magalasi komanso kufunsira kwamakampani, chonde pitani patsamba lathu ndikulumikizana nafe nthawi iliyonse.
