Niba ukunda kwambara indorerwamo, ugomba gutekereza ku birenze imibare iri ku muti wawe. Hari kandi ikintu cy'ingenzi kimwe, ariko wenda kitazwi cyane, ushobora kuba utari warigeze wumva. Icyo ni igipimo cyitwa Pupillary Distance, cyangwa 'PD' mu magambo ahinnye. Reka turebe icyo ari cyo, impamvu ari ingenzi cyane, n'uburyo bwo kubipima mu rugo.
Mu magambo make, intera y'umwana (PD) ni iki?
Intera y'impinja (PD) ni intera iri hagati y'ingingo zo hagati z'impeta ebyiri z'umukara (pupils) mu maso yawe. Ipimwa muri milimetero (mm). Rimwe na rimwe yitwa ``Intera y'impinja - ID''.
Tekereza, iyo urimo gukora indorerwamo, ugomba guhindura lens kugira ngo aho ingufu zigarukira habe neza neza imbere y'amaso yawe. Bitabaye ibyo, ntuzabona neza. Aha niho gupima PD ari ngombwa kugira ngo ukore ihinduka rikwiye. Niba urimo kugura indorerwamo kuri interineti, uzakenera iki gipimo cya PD hamwe n'umuti wawe.
Ni gute wapima PD yawe mu rugo?
Uburyo bwiza bwo gupima ni ukubikorerwa n'inzobere mu by'amaso, nka muganga w'amaso cyangwa umuganga w'amaso, kuko ubwo buryo ari bwo bwiza cyane.
Ariko, niba ushaka kwipimisha, hari uburyo bwo kubikora. Icyo ukeneye gusa ni agapapuro ko gupimisha kanditseho milimetero (mm) n'indorerwamo. Hari igihe ushobora kubona agapapuro ko gupimisha kadasanzwe cyangwa porogaramu za telefoni zigendanwa zagenewe iyo ntego. Ariko ibuka ko ubuziranenge bushobora kuba buke iyo wipimye cyangwa ukoresheje porogaramu.
Niba ushaka kwipimisha...
Niba ubikora wenyine, ugomba kwitonda gato. Kurikiza izi ntambwe.
| Intambwe | Icyo gukora |
|---|---|
| 1. Kwitegura | Ahantu hafite urumuri rwinshi, hagarara imbere y'indorerwamo nko muri santimetero 18 uvuye aho uri. |
| 2. Gushyira ahantu ho gukandagiraho ibirenge | Hindura ibimenyetso bya milimetero kuri kaseti kugira ngo bigaragare mu ndorerwamo, hanyuma ubishyire munsi y'amaso yawe no hejuru y'izuru ryawe. Nk'aho ureba hejuru y'urukuta. |
| 3. Gupima ijisho ry'iburyo | Funga ijisho ryawe ry'ibumoso. Ukoresheje ijisho ryawe ry'iburyo gusa, shyira ikimenyetso cya zeru (0) ku gatambaro neza neza hagati mu ruziga rw'umukara rw'ijisho ryawe ry'iburyo. Ntukureho agatambaro uhereye aha. Niba bigenze bityo, tangira wongere. |
| 4. Gupima ijisho ry'ibumoso | Noneho fungura ijisho ryawe ry'ibumoso hanyuma ufunge ijisho ryawe ry'iburyo. Urebye mu jisho ryawe ry'ibumoso gusa, reba ikimenyetso cya milimetero kiri hagati mu ruziga rw'umukara rw'ijisho ryawe ry'ibumoso. |
| 5. Gupima | Agaciro ka milimetero uzasanga ni ko kazaba ari ko gupima kwawe kwa PD. |
Niba upimye ukoresheje ubufasha bw'umuntu...
Ibi biroroshye kuruta kubikora wenyine. Umuntu ugufasha agomba kubikora muri ubu buryo.
| Intambwe | Icyo umufasha agomba gukora |
|---|---|
| 1. Kwitegura | Icara imbere y'umuntu ushaka gupima, nko muri santimetero 30 uvuye aho uri. Komeza amasura yawe yombi ku rwego rumwe. |
| 2. Gushyira ahantu ho gukandagiraho ibirenge | Shyira ikirenge munsi y'amaso y'undi muntu hejuru y'izuru rye. |
| 3. Gupima ijisho ry'iburyo | Saba umuntu ugupimisha kureba mu jisho ryawe ry'ibumoso (umuntu ugufasha) . Shyira zeru (0) ku gapapuro ko gupimisha ku nkengero y'inyuma y'impeta y'umukara y'ijisho ry'iburyo ry'undi muntu. Ntukimure agapapuro ko gupimisha uhereye aha. |
| 4. Gupima ijisho ry'ibumoso | Noneho saba undi muntu kureba mu jisho ryawe ry'iburyo . Noneho reba ikimenyetso cya milimetero gihuye n'inkombe y'imbere y'impeta y'umukara iri ku jisho rye ry'ibumoso. |
| 5. Gupima | Iyo millimetero ubona ni yo gipimo cye cya PD. |
Kuki iki gipimo cya PD ari ingenzi cyane?
Urabizi, tubona ibintu iyo urumuri rwinjiye mu jisho. Uru mucyo winjira mu jisho unyuze mu mboni. Hanyuma urwo mucyo unyura muri lens ugashyira ku mboni.
Ariko niba ufite amaso atabona neza, uru rumuri ntirwibanda neza. Niyo mpamvu tubona ibintu bidasobanutse neza. Urugero:
- Kureba kure/Kurwara cyane
- Kureba hafi/Myopia
- Kugorwa no kureba hafi uko ugenda ukura (Presbyopia)
- Ubwijime
Indorerwamo z'amaso si zimwe gusa. Ziratandukanye bitewe n'ibintu byinshi, nko kuba ufite ikibazo cyo kubona neza ndetse n'imbaraga z'umuti wahawe.
Iki gipimo cya PD kigomba kuba gikwiye kugira ngo imbaraga z'indorerwamo z'indorerwamo zibashe kwerekeza neza hagati mu mboni y'amaso yawe. Icyo gihe ni bwo ushobora kubyaza umusaruro byinshi indorerwamo no kubona isi neza.
Tekereza uko byagenda iyo igipimo cya PD kiba kitari cyo...
Niba indorerwamo ukoresha zakozwe ku gipimo kibi cya PD, nta kabuza uzatangira kubyumva.
- Gutera amaso
- Umutwe
- Kugoreka amaso (kubona ibintu nk'aho byarambuye)
Nubwo ibi bimenyetso atari bibi, birababaza cyane. Byongeye kandi, gukomeza kubabara amaso bishobora gutuma amaso yawe arushaho kuba mabi.
Uburebure busanzwe bwa PD ku muntu mukuru ni nka mm 63. Ariko, bushobora kuva kuri mm 50 kugeza kuri 70. Buratandukanye bitewe n'umuntu. PD yawe ishobora guhinduka uko ukura uri umwana, ariko ubusanzwe ntabwo ihinduka uko ukura ubaye umuntu mukuru. Ariko, gake cyane, ishobora guhinduka gato nyuma yo kubagwa mu maso cyangwa mu maso.
Ni ryari bidakwiye gupima PD yawe ubwawe?
Niba usanzwe ukoresha indorerwamo zawe ku ntego imwe (urugero, gusoma), kubona ibipimo byawe bwite bishobora kuba atari ikibazo gikomeye. Ariko, hari ibihe bimwe na bimwe byihariye aho ukeneye gupimirwa ku rwego rw'umwuga . Kugerageza kubona ibipimo byawe bwite ntabwo ari igitekerezo cyiza muri icyo gihe.
| Amahirwe | Impamvu |

| Niba ukeneye lentile nyinshi | Izi zizwi kandi nka "Progressive lenses, bifocals, trifocals". Izi lenses zifite imbaraga zitandukanye mu bice byinshi. Kubwibyo, iyo igipimo cya PD kitari cyagera kuri milimetero imwe, kureba bishobora guhinduka burundu. |
| Niba ukeneye kwambara indorerwamo igihe cyose kugira ngo urebe hafi na kure | Iyo turebye ikintu hafi, PD yacu igabanukaho milimetero zigera kuri 3. Iri tandukaniro rigomba kwitabwaho mu gihe cyo gushushanya indorerwamo nk'izi. Gupima neza ni ingenzi kuri ibi. |
| Niba ufite ikibazo mu maso yawe | Mu buvuzi, ibi byitwa ``Strabismus.'' Muri iki gihe, hagomba gupimwa ibipimo bitandukanye kuri buri jisho kandi indorerwamo zigomba gukorwa neza cyane. |
Hari ibihugu bimwe bifite amategeko asaba ko ibipimo bya PD bishyirwa mu nyandiko yawe y'indorerwamo z'amaso. Nubwo nta tegeko nk'iryo rihari mu gihugu cyacu, ushobora gusaba muganga w'amaso cyangwa umuganga w'amaso ibipimo bya PD. Ni uburenganzira bwawe.
Ubutumwa bwo kujyana mu rugo
- Intera y'amaso y'umuhondo (PD) ni intera iri hagati y'impeta z'umukara z'amaso yawe. Iki gipimo ni ingenzi kugira ngo ubone indorerwamo zikwiriye.
- Kwambara indorerwamo zakorewe ku gipimo kibi cya PD bishobora gutera umunaniro mu maso, kuribwa umutwe, no kutabona neza.
- Nubwo ushobora gupima iki gipimo uri mu rugo, uburyo bwiza kandi bwizewe ni ukugipima n'umuhanga.
- Menya neza ko upimwe n'abaganga b'inzobere, cyane cyane niba ukoresha lenses nyinshi cyangwa ufite indwara nka strabismus.
- Niba imiti yawe idakubiyemo ibipimo bya PD, ntutinye kubaza muganga wawe cyangwa umuganga w'amaso ibyayo.
