Iinyaniso ezingama-25 malunga neeGlasi - Ezivela kooGqirha bamehlo nakubanini beevenkile

1. I-Myopia ebantwaneni

Nje ukuba kufunyaniswe ukuba i-myopia yokwenyani ifunyenwe, kufuneka kunikwe iiglasi zokulungisa amehlo kwaye zinxitywe. Ukulibazisa ukulungiswa kunokubangela ukwanda kwamanani ngonyaka. Iidigri ezili-100 ukuya kwezili-150.

2. Unyango lwe-Myopia

Nayiphi na ivenkile ethi iyakwazi "ukunyanga" i-myopia kwaye "inciphise amayeza kagqirha" (uqeqesho lokubona, amayeza esintu, amabala amehlo, njl.njl.) bubuqhetseba.

3. Ukukhetha ilensi

Ixabiso liphezulu hayi intsingiselo efanelekileyo. Khetha i-refractive index ngokusekelwe kumyalelo kagqirha:

• Ukuya kuthi ga kwi -3.00D: Isalathisi se-1.56

• -3.00 ukuya ku -5.00D: Isalathisi se-1.60

• -4.00 ukuya ku -7.00D: Isalathisi se-1.67

• Ngaphezulu -6.00 ukuya -7.00D+: Isalathisi se-1.74

4. Iilensi zoqhagamshelwano

Nxiba iilensi zokunxibelelana ngaphantsi kweeyure ezi-8 ngemini kwaye ungaze ulale kuzo. Okukhona umjikelo umfutshane, kokukhona usempilweni - Beka phambili izinto ezilahlwayo zemihla ngemihla kunye nezinto ezilahlwayo zenyanga.

5. Amaconsi amehlo

Kuphephe ukusetyenziswa ixesha elide ngaphandle kwengcebiso kagqirha. Xa udiniwe ngamehlo, ukuphumla kudla ngokuba luncedo ngakumbi kunamathontsi amehlo.

6. Umgaqo wokunxiba

Abantu abangaboni kakuhle bangaphantsi 0.3 Ufanele anxibe iiglasi rhoqo ukuthintela ukukhula ngokukhawuleza kwe-myopia okubangelwa kukudinwa kwemisipha ye-ciliary.

7. Uvavanyo lwamehlo lwabantwana

Abantwana abangaphantsi kweminyaka eli-10 ubudala kufuneka bahlolwe amehlo abo ngokuvuleka kwezibuko zabo zokuqala ukuze kuthintelwe i-pseudomyopia.

8. I-Presbyopia

Abantu abane-myopia nabo baya kuba ne-presbyopia njengoko bekhula, nangona isenokulibaziseka okanye ithintelwe kancinci kukubona izinto ezikufutshane.

9. Iiglasi zelanga

Enye yezona ndlela zisebenzayo zokuthintela i-cataracts. Qiniseka ukuba ukhetha Isiqinisekiso se-UV400 Iiglasi zelanga zokwenyani. Abantu abathanda ukukhanya kwelanga banokukhetha iiglasi zelanga ezibhalwe ngugqirha.

10. Iimbombo

Ukugquma iliso elinye ixesha elide nge-bangs kunokubangela okanye kuyenze mandundu i-myopia.

11. Iimpawu zesilumkiso

Ukuba umntwana wakho uhlala ejika amehlo, etyekisa intloko yakhe, okanye ehlikihla amehlo akhe, khangela ugqirha ngokukhawuleza.

12. Ukudlala ipiyano kunye ne-myopia

Ukuziqhelanisa nepiyano kufuna ukugxila kakhulu kumculo wephepha kunye nekhibhodi, nto leyo ebangela ukukhathala kwamehlo ngokulula. Umthetho we-20-20-20 (jonga into ekude kangangeemitha ezingama-20 imizuzwana engama-20 rhoqo emva kwemizuzu engama-20).

13. Ukukhetha ifreyimu yeglasi

Intuthuzelo > Ubuhle. Iifreyimu ezingalungiswanga kakuhle zezona zinto ziphambili ezibangela iintloko ezibuhlungu kunye noxinzelelo lwamehlo.

14. Ukuthintela ukukhanya okuluhlaza okwesibhakabhaka akuyomfuneko

Ngaphandle kokuba uchitha iiyure ezingaphezu kwesibhozo ngosuku phambi kwezikrini, iilensi ezivimba ukukhanya okuluhlaza okwesibhakabhaka azinanzuzo ingako. Iilensi eziluhlaza okwesibhakabhaka ezikumgangatho ophantsi zinombala otyheli oqinileyo oyenza ibe mandundu ingxaki yamehlo. Kubaluleke kakhulu ukutyala imali kuyo. iilensi zokuhambisa ukukhanya okuphezulu kwaye iingubo ezilungileyo.

15. Ukhathalelo lweLensi lumisela ixesha lokuphila

Soloko uhlamba ngamanzi acocekileyo ngaphambi kokuba usule kancinci ngelaphu le-microfiber lelensi. Iilensi zokusula ezomileyo zifana nokuzigquma ngephepha lokugquma. Kwanezo zigqumayo ziqinileyo ziya kukrwelwa ngamasuntswana othuli.

16. Iiglasi zamehlo zinomhla wokuphelelwa

Nokuba amayeza akho akatshintshanga, iilensi kufuneka zitshintshwe rhoqo Iinyanga ezili-18 ukuya kwezingama-24Ngaphaya koko, iilensi zinokongeza i-oxidize kwaye zibe tyheli, uboya bunokonakala, kwaye ukuhanjiswa kokukhanya kuncipha kakhulu. Oku kubangela ukuba amehlo akho azibhokoxe ngakumbi ngokungazi.

17. Ukuthenga iifreyimu kwi-intanethi kuneengozi ezinkulu

Intuthuzelo yesakhelo ixhomekeke kwi ukulingana kwamanqaku amathathu: ii-nose pads, i-temple curve, kunye ne-frame front wrap. Ezi kufuneka zilungiswe ngokwazo. Ii-frames ezikwi-intanethi zingabonakala zingabizi kakhulu, kodwa zihlala zifuna ukulungiswa kobuchwephesha emva koko, kwaye izinto ezininzi azinakulungiswa kwakhona.

18. Ukufumaneka kweoksijini kubaluleke ngaphezu komthamo wamanzi kwiilensi zoqhagamshelwano

Xa uthenga iilensi zokunxibelelana, musa ukugxila kuphela kumthamo wamanzi. Ukufumaneka kweoksijini (Dk/t) luphawu oluphambili olubonisa ukuba i-cornea iyakwazi na “ukuphefumla,” ingakumbi kwabo banxibe ixesha elide. Izixhobo ze-silicone hydrogel Ngokuqhelekileyo inika ukufumaneka okuphezulu kweoksijini.

19. Iilensi ezilwa nokudinwa ziilensi ezisebenzayo, azizongezo zempilo

Ziilensi eziphuculiweyo zokubona okukodwa. Amandla ongezelelweyo kwicandelo elisezantsi anceda ekunciphiseni umgudu wokugxila. Zifanelekile kubantu abakufutshane Uneminyaka engama-40 ubudala abaqala ukuba ne-presbyopia, okanye abo badinwe kakhulu emehlweni. Ulutsha kunye nabantu abaneendawo zokuhlala eziqinileyo abazidingi konke konke.

20. Musa ukuncama ukusebenza kwe-optical ngenxa yeelensi ezincinci

Xa iilensi ezibhalwe ngugqirha ophezulu ezidlulayo ukupolisha umphetho iba yingqukuva emacaleni, nto leyo ebangela ukuphazamiseka okukhulu kokukhanya. Oku kubonakala ngakumbi xa uqhuba ebusuku, njengoko izibane zecala zingajika zibe ngukukhanya okukhulu. Akukhuthazwa ukuba kwenziwe ngaphandle kokuba kuyimfuneko.

21. Kubantwana, ukujonga ubude beliso rhoqo kubaluleke ngakumbi kunovavanyo lokurhawuzelelwa

Ingundoqo yokulawula i-myopia kubantwana nakwishumi elivisayo kukuba ukulawula ukukhula kobude be-axialUkulinganisa ubude be-axial nganye Iinyanga ezi-3–6 yeyona ndlela ifanelekileyo yokuvavanya ukusebenza kakuhle kweendlela zokulawula i-myopia (ezifana neelensi ze-orthokeratology okanye iilensi ze-defocus).

22. Ukuphucuka ngequbuliso ekuboneni kunokubonisa isifo

Ukuncipha kwe-myopia kubantu abakwiminyaka ephakathi kunye nabantu abadala kunokubonisa ukuba i-cataracts okanye iswekile yegazi iyatshintshatshintsha. Naluphi na utshintsho olukhawulezileyo emehlweni kufuneka lubangele ukuba kufuneke udliwanondlebe nogqirha endaweni yokutshintsha iiglasi zamehlo ngokukhawuleza.

23. Iilensi ezilwa nenkungu zifuna ukulungiswa rhoqo

Iingubo ezichasene nenkungu zihlala ixesha elide Iinyanga ezi-6–12 kwaye akufuneki zisulwe ngephepha. Isisombululo esisebenzayo sokuthintela inkungu yindibaniselwano yesitshizi sokuthintela inkungu kunye neendlela ezifanelekileyo zokucoca.

24. Uqeqesho lokusebenza ngokubona asikokukhwabanisa

Kwabo bangenazo iindawo zokuhlala kakuhle okanye i-binocular fusion engaqhelekanga, uqeqesho lomsebenzi wokubona olulungiselelwe wena lunokuba luncedo ngakumbi kunokutshintsha nje iiglasi. Nangona kunjalo, kubalulekile ukuphepha izixhobo zoqeqesho ezibizwa ngokuba “zifanelana nobukhulu obunye”

25. Ingcebiso yokugqibela

Ukufakela izibuko zamehlo yinkqubo yezonyango. Ukufakela izibuko zamehlo ngobuchwephesha kubaluleke ngokuphindwe kalishumi kunamaxabiso aphantsi. Themba iingcali, hayi intengiso.
