Yimuphi Umehluko Phakathi Kwezingilazi Nemiyalelo Yoxhumana Nabo?
Imiyalelo yelensi yokuxhumana nezibuko ihlukile ngoba izibuko namalensi okuxhumana abekwe ngendlela ehlukile esweni lakho. Izibuko zihlala cishe amamilimitha ayi-12 ukusuka esweni, kuyilapho abathintwayo behlala ngqo endaweni yamehlo. Lawa mamilimitha angu-12 enza umehluko omkhulu futhi angashintsha ngokuphawulekayo imiyalelo yemithi phakathi kwakho kokubili.
Futhi, imiyalelo yelensi yokuxhumana idinga ukucaciswa okwengeziwe kunezibuko. Lokhu kubandakanya:
1. Ububanzi beLens: Ububanzi belensi bucacisa usayizi welensi njengoba ukalwa esweni lakho. Ububanzi bebanga labathintana nabo abathambile busuka ku-13.5 kuya ku-14.5 millimeters, kanti ububanzi bokuthintwa oqinile busuka ku-8.5 kuya ku-9.5 millimeters. Lawa ma-diameter awalingani-konke, yingakho edinga ukuhlolwa kokufaka othintana naye.
2. Ijika Eliyisisekelo: Ijika eliyisisekelo liwukugoba kwelensi yangemuva futhi kunqunywa ukuma kwe-cornea yakho. Leli jika linquma ukulingana kwelensi eqinisekisa ukuthi ihlala endaweni.
3. Ibhrendi yelensi: Ngokungafani nezibuko, imiyalelo yokuxhumana nayo ihlanganisa uhlobo oluthile lwamalensi.
Zisho Ukuthini Izifushaniso Ngemiyalelo Kadokotela?
Sihlanganise izingxenye ezengeziwe zemiyalelo yokuxhumana. Noma kunjalo, ungase ubone izifinyezo ongazazi kumalensi akho othintana naye kanye nemiyalelo yezibuko. Ake sibuyekeze ukuthi lezi zifinyezo zisho ukuthini ukuze uqonde kangcono iziqondiso zakho kanye nomehluko phakathi kwazo.
1. I-OD noma i-Oculus Dexter: Lokhu kumane kubhekisele esweni langakwesokudla. Kuvamile futhi ukubona okuthi "RE".
2. I-OS noma i-Oculus Sinister: Leli gama libhekisela esweni langakwesokunxele. Kuvamile futhi ukubona okuthi "LE".
3. I-OU noma i-Oculus Uterque: Lokhu kubhekisela kuwo womabili amehlo.
4. I-Minus Sign noma (-): Ibonisa ukubona eduze.
5. Isibonakaliso Sokuhlanganisa noma (+): Ibonisa ukubona kude.
6. I-CYL noma Isilinda: Icacisa inani lamandla adingekayo ukuze kulungiswe i-astigmatism.
Ungakwazi yini ukuguqula incwadi kadokotela yengilazi ibe ethintwayo?
Manje njengoba usufundile umehluko phakathi kokuthintana nencwadi kadokotela yezibuko, ungase uzibuze ukuthi ingabe incwadi kadokotela yezibuko ingaguqulwa ibe incwadi kadokotela yelensi yokuxhumana. Impendulo elula kulokhu ithi “cha”. Ngaphandle kwamashadi nokuguqulwa okuthunyelwe ku-inthanethi, incwadi kadokotela yothintana naye idinga ukuhlolwa kwamehlo kanye nokufakwa kwelensi yokuxhumana ukuze kulawulwe udokotela wamehlo onelayisensi.
Ubuhle Nebubi Bokugqoka Izibuko Zamehlo
1. Izibuko zamehlo zinikeza lula; zisuswa kalula uma kunesidingo.
Izibuko zinikeza ukukhetha okulungiswa kahle okuphansi kubantu abadinga kuphela ukulungiswa kokubona kwemisebenzi ethile 2., njengokufunda, ukushayela noma ukusebenzisa amadivaysi edijithali.
Ukugqoka izibuko kuvimbela abantu ukuthi bathinte amehlo abo, kunciphisa ingozi yokutheleleka nokucasuka.
3. Izibuko zivikela amehlo emfucumfucu nasezintweni, njengezinhlayiya zothuli, umoya nemvula.
4. Izibuko zingase zinikeze isivikelo emisebeni ye-ultraviolet, kuye ngohlobo lwamalensi (isb., izibuko zelanga noma amalensi asebenza ekukhanyeni).
5. Izibuko ezinakekelwa kahle zingahlala iminyaka ngaphambi kokudinga ukushintshwa (uma incwadi yakho kadokotela ingashintshi).
Yini Okufanele Uyilindele Ngesikhathi Sokuhlolwa Kwelensi Yokuxhumana?
Lokhu kuhlolwa kufaka phakathi ingxoxo mayelana nendlela yakho yokuphila iyonke kanye nokuhlolwa kwamehlo. Udokotela wakho wamehlo uzohlola ukugoba kwe-cornea yakho ukuze aqinisekise ukuthi amalensi akho amasha alingana kahle. Usayizi womfundi wakho usiza ukunquma usayizi welensi yakho.
Uma ufuna izibuko noma incwadi kadokotela yelensi yokuxhumana, udokotela wakho wamehlo angakusiza. Bangakwazi ukuhlola impilo yamehlo akho jikelele kanye nokubona futhi banqume izinketho eziphumelela kakhulu.
