yu no di ekzak distans bitwin yu tu yay in blak ring (pupillary distance)? Dis rili impɔtant fɔ pipul dɛn we de wɛr glas!

Yu na pɔsin we de wɛr glas? Ɔ yu de luk fɔ gɛt wan? If na so, tide wi go tɔk bɔt sɔntin we rili impɔtant we yu de pik glas we fit yu yay fayn fayn wan. dis na mεzhɔ we dεn kכl ‘Pupillary Distance’ . Sɔntɛm yu nɔ bin dɔn yɛri dis wɔd bifo. Bɔt, i rili impɔtant fɔ mek yu si klia wan.

Wetin na dis ‘pupillary distance’?

Fɔ tɔk am simpul wan, Pupillary Distance , ɔ PD fɔ shɔt, na di distans frɔm di sɛntrɔm pan yu pupil (di blak sɛklɔ we de na di midul pan yu yay) to di sɛntrɔm pan yu pupil na yu ɔda yay. Dɛn kin mɛzhɔ dis insay milimita (mm). Sɔntɛnde, di wan dɛn we sabi bɔt di yay kin kɔl dis di Interpupillary Distance (ID) .

We dɛn gi yu prɛskrishɔn fɔ glas, dis PD valyu rili impɔtant. Na bikɔs di lens dɛn na di glas dɛn nid fɔ ajɔst jɔs bifo yu yay. Na da tɛm de yu kin gɛt di klia vishɔn we pɔsin kin si. If yu de bay glas ɔnlayn, yu go mɔs nid dis PD valyu wit di prɛskrishɔn frɔm yu yay ɛgzam.

A kin mɛzhɔ dis na os? Aw a go du am?

Yes, yu kin tray fɔ mɛzhɔ yu PD na os if yu want. Bɔt fɔ mek yu ebul fɔ mɛzhɔ di rayt we, i go fayn fɔ mek pɔsin we tren fɔ kia fɔ di yay mɛzhɔ am . Bikɔs ivin if yu chenj smɔl smɔl fɔ sɔm milimita, dat kin afɛkt di we aw yu de si tin.

Bɔt if yu want fɔ tray am yusɛf, ɔl wetin yu nid na rula we dɛn mak wit milimita (mm) ɛn miro. Speshal rula dɛn de we de na di intanɛt we dɛn mek spɛshal fɔ mɛzhɔ PD. Sɔm smart fon ap dɛn de bak we se dɛn go ɛp yu fɔ tek dis mɛzhɔmɛnt. Bɔt i nɔ kin izi fɔ mek yu rili biliv se di mɛzhɔmɛnt kɔrɛkt, ilɛksɛf yu mɛzhɔ am yusɛf ɔ yu yuz ap.

If yu want fɔ mɛzhɔ yusɛf, na dis we:

Dis kin tranga smɔl, so yu nid fɔ peshɛnt.

1. Fɔs, tinap bifo miro na say we gɛt layt. Kip yu fes lɛk 18 inch so frɔm di miro.

2. Naw, ol di rula ɔp to yu fes so dat yu go si di milimita mak dɛn. Yu want fɔ ol di rula lɛk se yu de luk wan wɔl, jɔs dɔŋ yu yay.

3. Klos yu lɛft yay.

4. Naw, we yu luk wit yu rayt yay nɔmɔ, put di ziro (0) mak na di rula jɔs lɛk di midul pan yu rayt yay in blak sɛklɔ. Imajin se wan layn de we de sheb di blak sɛklɔ jɔs insay tu, ɛn di ziro fɔ de na da layn de. No muv di rula na dis point, okay? If yu du dat, yu go gɛt fɔ bigin bak.

5. Okay, nau opin yu lef ai and klos yu rait ai.

6. Naw, we yu luk onli wit yu lef ai, fain di milimita mak we de ekzakli fo midul yu lef ai blak sirkul. Jɔs lɛk bifo, if yu imajin di blak sɛklɔ de jɔs insay tu, di milimita mak we de nia da sɛnta de na yu PD valyu.

Mɛmba se: Fɔ mɛzhɔ dis we yu wan kin at smɔl, ɛn mistek kin apin. So gɛt ɛp if i pɔsibul.

I kin izi fɔ yu if yu mɛzhɔ wit pɔsin in ɛp!

I kin izi fɔ yu if sɔmbɔdi ɛp yu. Na dis na aw fɔ du am:

1. Di pɔsin we de mɛzhɔ yu PD fɔ sidɔm bifo yu, wit lɛk 18 inch bitwin yu fes.

2. I fɔ ol di rula te yu fes, so dat i go si di milimita mak dɛn. Di rula fɔ de ɔnda yu yay (lɛk se yu de luk am frɔm ɔp wɔl).

3. Naw, luk stret na di pɔsin we de mɛzhɔ yu PD in lɛft yay. Frɔm dis tɛm, tray nɔ fɔ muv yu ed.

4. Di pɔsin we de mɛzhɔ fɔ put di ziro (0) mak na di rula so dat i go de na di ɔda ed pat pan yu rayt yay in blak ring (dat na di edj fɔ yu rayt yay in blak ring we dɛn kin si frɔm dɛn lɛft). Nɔ mek di rula muf dis tɛm, ɔ yu go gɛt fɔ bigin bak.

5. Naw, luk stret na di rayt yay fɔ di pɔsin we de mɛzhɔ yu PD.

6. Di pɔsin we de mɛzhɔ fɔ luk di milimita mak we de nia di insay ed pat pan yu lɛft yay in blak ring (dat na di edj fɔ yu lɛft yay in blak ring we dɛn kin si frɔm dɛn rayt). Dat milimita mak na yu PD valyu.

Wetin mek dis ‘pupillary distance’ (PD) impɔtant so?

Tink bɔt am dis we: di pupil dɛn na yu yay tan lɛk di lens dɛn na kamɛra. Layt kin go insay tru dɛn tin ya. Dɔn, dis layt de pas tru di lens we de insay di yay ɛn fɔdɔm pan di retina we de biɛn di yay. Na da tɛm de wi de si.

Bɔt if yu nɔ de si fayn, dis layt nɔ de fos fayn. Na dat mek wi de si sɔm distans dɛn we nɔ klia. Na sɔm ɛgzampul dɛn ya:

• Farsightedness/Hyperopia - kin si klia wan klos bɔt nɔ kin si fa.
• Nearsightedness/Myopia - I kin si klia wan na distans bɔt i nɔ kin si nia.
• Presbyopia - na wan sik wae kin afɛkt bɔrku pipul dɛm afta dɛn dɔn ol 40 ia.
• Astigmatism - Layt nɔ de fכkus fayn bikɔs ɔf di chenj na di shep na di yay.

We i kam pan glas, nɔto ɔlman go gɛt di sem kayn glas. De rizin fɔ dis na bikɔs bɔrku tin kin afɛkt yu yay, lɛk aw yu gɛt prɔblɛm wit yu yay, ɛn di nɔmba fɔ di digri dɛm wae yu gɛt fɔ gɛt astigmatism.

bay we yu mכsu yu PD kכrekt wan εn ajɔst di optik sεntrכm fכ yu lεns dεm so dat dεn go sεntrεd na di sεntrכm fכ yu kכnia, yu go gεt di mכst כlt fכ yu lεns dεm. Dis go mek yu si klia wan ɛn fayn fɔ si.

Na ‘Nasopupillary Distance’ na sɔntin lɛk dis?

Yes, ɔda impɔtant mɛzhɔmɛnt de apat frɔm PD, we naDistans we di Nasopupilari de mek . Dis na di distans frɔm di midul pan yu blak yay to di midul pan di brij na yu nos.

Imajin, 4 pan ɛvri fayv pipul dɛn nɔ gɛt dɛn yay ɛn nos we rili simɛtrik. dat min se di `Nasopupillary Distance` nכ de di sem fכ di tu yay dεm. Bɔku tɛm, dis difrɛns nɔ kin rich 2 milimita (2mm). Bɔt fɔ lɛk wan pan siks pipul dɛn, dis difrɛns kin pas 2 milimita (2mm). Bikɔs dis distans smɔl, bɔku pipul dɛn nɔ kin ivin notis am ɔ no bɔt am. Bɔt dis kin afɛkt bak di we aw dɛn mek di glas dɛn, mɔ di lens dɛn we gɛt bɔku tin dɛn fɔ du.

Wetin kin apin if di ‘Pupillary Distance’ (PD) mɛzhɔmɛnt nɔ kɔrɛkt?

Imajin wetin go apin if dɛn fit yu wan glas we dɛn nɔ mɛzhɔ kɔrɛkt wan fɔ yu PD. Yu go mɔs bigin fɔ gɛt diskɔmfɔt lɛk dis:

• Aystrayn we de mek pɔsin in yay strɛch
• Ed de at
• Distɔrshɔn na yu vishɔn - tin dɛn kin tan lɛk se dɛn dɔn distɔrj ɔr dɛn dɔn distɔrj

Pan ɔl we dɛn sayn ya nɔ kin rili denja, dɛn kin mek yu nɔ fil fayn. Dɔn bak, yu yay kin wɔs bikɔs yu yay kin strɛs we yu nɔ nid fɔ si. Na dat mek i impɔtant fɔ gɛt di rayt PD.

dis ‘pupillary distance’ (PD) de chenj wan wan tεm?

We yu yɔŋ, dis PD kin chenj as yu de gro. Dat min se di PD we yu gɛt we yu yɔŋ nɔto di sem wit we yu yɔŋ. Bɔt dis PD valyu nɔ kin chenj afta yu dɔn big.

Bɔt, sɔm kayn tin dɛn de we nɔ kin apin so ɔltɛm we i kin chenj. Fɔ ɛgzampul, if yu gɛt fɔ du ɔpreshɔn pan yu yay ɔ yu fes, yu PD kin chenj smɔl afta da ɔpreshɔn de.

Wetin na di avrej ‘pupillary distance’ (PD)?

di avrej PD valyu fכ big man na bכt 63 milimita `(63mm)`. Bɔt dis kin difrɛn frɔm wan pɔsin to ɔda pɔsin. כl di big pipul dεm gεt PD valyu bitwin 50 εn 70 milimita `(50mm - 70mm)`. Smɔl nɔmba pan pipul dɛn PD valyu kin difrɛn ausayd dis rεnj. Sɔm pipul dɛn kin gɛt valyu we smɔl lɛk 45 milimita `(45mm)`, we ɔda wan dɛn kin gɛt valyu we ay lɛk 80 milimita `(80mm)`.

Us sityueshɔn dɛn wi nɔ fɔ abop pan wi yon jɔjmɛnt?

If yu de yuz yu glas fɔ wan tin nɔmɔ (fɔ ɛgzampul, fɔ rid buk ɔ fɔ du layt wok), yu PD fɔ fayn fɔ dat. Bɔt sɔm kes dɛn de we i nid fɔ mɛzhɔ yu PD rili kɔrɛkt wan . Dis na di kes dɛm:

• If yu nid multifocal lens: Dis na lens lek `progressive lens`, `bifocals` (lens we kin si ɔl tu fa ɛn nia), ɔ `trifocal` (lens we kin si ɔl di tri distans, intamɛdiet distans, ɛn nia). Fɔ mek ɛni pat pan dɛn lens ya kɔrɛkt wan, yu nid fɔ no di PD valyu rili kɔrɛkt wan.
• If yu nid fɔ kɔntinyu fɔ wɛr glas fɔ si nia ɛn fa:Bikɔs, we wi luk sɔntin we de bifo wi, wi PD kin smɔl smɔl bay lɛk 3 milimita (3mm).
• If yu gɛt ɛnitin we nɔ de alaynɛd ​​di ayris na yu yay (lɛk strabismus): Insay dɛn kayn tin ya, i impɔtant fɔ mek spɛshal pɔsin mɛzhɔ yu PD.

Insay kes dɛm lɛk dis, i bɛtɛ fɔ mek dɛn mɛzhɔ yu PD to pɔsin we de mɛn yu yay ɔ pɔsin we tren fɔ kia fɔ yu yay pas fɔ mɛzhɔ am yusɛf.

Wetin mek dɛn nɔ tɔk bɔt dis PD na mi glas prɛskrishɔn?

Dis na prɔblɛm we bɔku pipul dɛn gɛt. Insay sɔm kɔntri dɛn (fɔ ɛgzampul, Amɛrika) no lɔ nɔ de we se dɛn fɔ tɔk bɔt di PD valyu we dɛn de gi prɛskrishɔn fɔ glas. Bɔt sɔm stet dɛn gɛt dɛn kayn lɔ dɛn de. Insay Sri Lanka, bɔku tɛm yu ɔftalmolɔg ɔ di wan we mek di glas go mɛzhɔ dis PD valyu ɛn kip am wit dɛn.

Dɛn kin ebul fɔ gi yu PD valyu if yu aks. Bɔt sɔm ples dɛn kin pe fɔ am difrɛn we. Bɔt fɔ mek yu gɛt wan glas we fit yu fayn fayn wan, i impɔtant fɔ mek dɛn mɛzhɔ dis PD valyu kɔrɛkt wan. So, i fayn fɔ aks yu yay dɔktɔ ɔ yu ayglas shɔp bɔt dis.

So, na di mɛsej dɛn we pɔsin kin kɛr go na os:

Okay, so na sɔm tin dɛn we yu nid fɔ mɛmba frɔm wetin wi dɔn tɔk bɔt:

• Pupillary Distance (PD) na di distans bitwin di blak ring dεm na yu yay.
• Dis PD valyu rili impɔtant fɔ mek glas we de gi yu klia, kɔmfyut vishɔn .
• Pan ɔl we yu kin tray fɔ mɛzhɔ dis na os, i bɛtɛ fɔ mek pɔsin we sabi kia fɔ yu yay mɛzhɔ am fɔ mek yu mɛzhɔ am di rayt we.
• If di PD mɛzhɔmɛnt nɔr kɔrɛkt, yu kin gɛt diskɔmfɔt lɛk aw yu yay kin strɛs, yu ed kin at, yu nɔ kin si fayn , ɛn yu kin ivin de si fayn.
• di korekt PD valyu implεnt, spεshal wan if yu yuz mכltifokal lεns כ if yu gεt kכndyushכn lεk strabismus.

So, di nɛks tɛm we yu go fɔ fiks yu glas, pe atɛnshɔn smɔl to dis PD valyu. Na bikɔs ivin smɔl difrɛns we na wan ɔ tu milimita kin rili afɛkt yu yay! Tu yay we gɛt wɛlbɔdi na big valyu na layf.
