Zvaunoda Kuziva NezveInterpupillary Distance!

Ko peya yemagirazi inganzi inokwanisa sei? Kwete chete panofanirwa kuve neiyo diopter chaiyo, asi inofanirwawo kugadziriswa zvinoenderana nekwakaringana interpupillary chinhambwe. Kana paine chikanganiso chakakosha mukati me interpupillary chinhambwe, mupfeki anozonzwa kusagadzikana kunyangwe iyo diopter iri chaiyo. Saka nei isina kurongeka interpupillary chinhambwe ichikonzera kusagadzikana kupfeka? Nemubvunzo uyu, ngatitaure nezve imwe ruzivo nezve interpupillary kureba.

• Chii chinonzi interpupillary distance?

Nharaunda pakati penzvimbo dzejometri dzevadzidzi vemaziso maviri inonzi interpupillary distance. Muchinyorero cheOptometry, chidimbu ichi ndiPD, uye unit iri mm. Chete kana mutsara wekuona maziso ese ari maviri uchigona kupfuura nepakati yemaziso egirazi lens anogona kupfekwa zvakanaka. Nokudaro, paunenge uchigadzira magirazi, unofanira kuedza kuita nzvimbo ye optical center kureba kwemagirazi pedyo nechepakati pemvura yemaziso.

• Classification ye interpupillary chinhambwe?

Nekuti ziso remunhu rinochinjika mukati kuenda kumadhigirii akasiyana kana akatarisa madaro akasiyana. Kana chinhu chichionekwa chiri pedyo, ndipo panobva panyanya kusanganidzana maziso nemukati. Naizvozvo, zvichienderana nenhambwe yekutarisa, iyo interpupillary chinhambwe chakakamurwa kuita kure kure interpupillary kure uye pedyo interpupillary chinhambwe. Distance interpupillary distance inoshandiswa kumagirazi ekuona kure; iyo iri pedyo interpupillary distance inoshandiswa kune magirazi ari pedyo, ayo anozivikanwawo semagirazi emaruva.

• Ndedzipi nzira dzinowanzoshandiswa dzekuyeresa nhambwe ye interpupillary?

MuOptometry, maturusi akadai sepupillary distance rule, pupillary distance metre, uye komputa refractor anowanzo shandiswa kuyera. Tichitora iyo inonyanya kushandiswa interpupillary distance rule method semuenzaniso, ini ndichasuma muchidimbu nzira yekuyera ye interpupillary distance:

1. Chiremba wemaziso nemudzidzi vanogara pahurefu hwakafanana uye 40cm vakaparadzana.

2. Isa interpupillary distance rule yakachinjika pamberi pebhiriji remhino yemunhu uye pachinhambwe chakaenzana nechepakati pemagirazi emaziso. Usaitetemesa yakachinjika.

3. Rega mudzidzi atarise ziso rekuruboshwe rachiremba wemaziso nemaziso ose.

4. Chiremba wemaziso anovhara ziso rake rekurudyi otarisa neziso rake rekuruboshwe kuti mucherechedzo 0 wechikamu che interpupillary uende kumucheto wemukati memboni yeziso rekurudyi.

5. Chengetedza nzvimbo yeinterpupillary distance rule isina kuchinjwa, munhu wacho anotarisa ziso rekurudyi rachiremba wemaziso nemaziso ose, uye chiremba wemaziso anovhara ziso rekuruboshwe, otarisa neziso rekurudyi. Chikero chinoyanana neruta rwechinhambwe chepakati nechepanze pemboni yeziso rekuruboshwe ndicho Measured interpupillary distance ari chinhambwe.

• Sei iko kukanganisa mu interpupillary chinhambwe panguva yekugadzira magirazi kuchikonzera kusagadzikana?

Mushure mekunzwisisa mamwe manzwisisiro akajairika nezve interpupillary chinhambwe, ngatidzokere kumubvunzo wekutanga. Sei zvisiri izvo interpupillary kureba zvichikonzera kupfeka kusagadzikana?

Kana malenzi maviri akagadziriswa, kukanganisa kunoitika mukati me interpupillary chinhambwe, saka panofanirwa kuve ne (kana maviri) ziso (s) apo mwenje unogamuchirwa neakisi yekuona haugone kupfuura nepakati pekuona kwelenzi. Panguva ino, nekuda kweiyo prism effect yelens, gwara rechiedza rinopinda muziso rinoshandurwa, uye chinhu chemifananidzo chinoumbwa mumaziso maviri hachiwire panzvimbo dzinoenderana, zvichikonzera kuona kaviri (ghosting). Nekuda kweizvozvo, uropi hunobva hwagadzira reflex yekururamisa kugadzirisa mamhasuru ekunze uye kubvisa diplopia. Kana iyi nzira yekururamisa ichienderera mberi, ichakonzera kusagadzikana kune anopfeka, uye iyo yakakura kukanganisa, zvakanyanya kusatsungirirwa.

Kana iwe uchida kuziva zvakawanda nezve magirazi fashoni maitiro uye kubvunza indasitiri, ndapota shanyira webhusaiti yedu uye utibate isu chero nguva.
