Magalasi ndi diopters: maonekedwe, mitundu, zitsanzo ndi ndemanga

Mkubwela chilimwe, pamene ntchito dzuwa kufika pazipita kubwerera kutentha ndi kuwala mphamvu, ophthalmologists zambiri kukumbukira odwala kuti sangathe kokha maso anu kwa kuwala, koma akhalebe aone zabwino, zimene zikhoza kusintha kudacita - mothandizidwa diopters.

Osati kutetezedwa ku dzuwa ndi ntchito mkulu mphamvu kuwala, maso ongoyendayenda pafupifupi chimodzimodzi amayaka kuwala, komanso khungu. Magalasi, kwambiri zofooketsa ndi kamwazi kuwala kuteteza chamawonedwe mitsempha, mucosa ndi magazi zotengera, amene ali pafupifupi chitetezo dzuwa lowala. Anthu amene anali ndi mavuto ndi acuity zithunzi, anakumana ndi kusankha: kuteteza maso kapena muzitsutse ngozi ndipo ntchito magalasi ochiritsira ndi diopters.

Mfundo chitetezo dzuwa ndi diopters

Ndi mwayi atsopano luso vuto la kaphatikizidwe magalasi ochiritsira ndi kukonzedwa masomphenya akhoza kwathunthu kuthetsa. Vuto chipatala kapena matenda pakati, lomwe ndi malonda zilipo Optics, mugule magalasi ndi diopters. Iwo adzateteza ku cheza zoipa dzuwa, ndi acuity zithunzi amakhalabe pa mlingo woyenera. Kugula mankhwala amenewa ndi bwino mfundo apadera zogulitsa. Kugula kumsika sizitanthauza khalidwe la katundu, ndipo ndi ngozi za thanzi la diso.

Pa magalasi ndi diopters mitengo zingasiyane. Izi zidalira pa amasokoneza, Mlengi (akudziwika kapena mtundu osadziwika) ndi zina. Mtengo wa zitsanzo zambiri otsika-yotsiriza, pa avareji ku rubles 600 kwa 1500. Koma musanayambe kugula mankhwala, muyenera choyamba ndiweruzidwe ndi katswiri.

Ubwino wa dzuwa Optics ndi diopters

Zasonyezanso kuti anthu ambiri odwala pogwiritsa ntchito magalasi ndi diopters, pikulu ndi kupeza. Kuti timvetse zinthu motero kwathunthu kuteteza maso anu ku dzuwa vuto la mpumulo wabwino ndi ntchito mu malo lotseguka. Alimi anatha kusiyanitsa katundu wa gulu, ndipo lero mungachite zotsatirazi kwa magalasi ndi kusintha kwa:

• Magalasi ndi diopters madalaivala.
• Zitsanzo kusambira.
• Zitsanzo masewera.
• Magalasi ana.
• Magalasi ndi diopters ntchito kusangalala.

Nkofunika kuti ena mwa zitsanzo amagwira osati ntchito wawo mwachindunji, koma pa nthawi yomweyo kukhalabe kufunika acuity zithunzi.

kusankha Features

Matendawa mabungwe chingatithandize kusankha chitsanzo chabwino. M'pofunika kumbukirani kuti magalasi ndi diopters mwina amasiyana makhalidwe ena zinchito. Mwachitsanzo, magalasi chameleon pa kuwala kusintha mtundu magalasi owala, zosasonyeza mtundu wake weniweni akusindikiza, potero basi kusintha mlingo wa chitetezo cha mwana wa m'diso la. Mu Optics otsika kuwala kachiwiri kumakhaladi mandala, kusonyeza kuonjezera otaya kuwala pa Iris wa diso, amene kumathandiza overvoltage chamawonedwe mitsempha.

Mfundo zikuluzikulu muyezo kwambiri kwa matenda a tanthauzo la acuity zithunzi. Kuchokera pa zotsatira, kusankha Optics bwino. Chofunika kwambiri: lamanzere ndi lamanja Maso ako akhale ndi magawo osiyana, mu nkhani iyi, disolo ndi diopters ufulu kuitanitsa payekha.

magawo kuwala kuti ayenera kumwedwa nkhani

Mulimonsemo, pamaso panu kugula magalasi ndi diopters, m'pofunika kulabadira mfundo zotsatirazi:

• Mlengi. Wotchuka kwambiri ndi Mlengi, ndi apamwamba khalidwe la magalasi ndi mafelemu.
• Ziyenera kukhala mokakamizidwa kuyesa ndi kuyesa chitsanzo akufuna.
• Anti-chimawala ❖ kuyanika pa magalasi, ndilo chitetezo chachikulu ndi nkhondo ya cheza ultraviolet pa diso, chofunika zitsanzo zimenezi.

Bad ❖ kuyanika wosanjikiza kapena sanamwe monga yosokoneza chitsanzo chachilengulengu ndi imfa ya mitundu amasonyeza otsika khalidwe.

Galasi kapena mapulasitiki

chakuti magalasi pulasitiki kwa nthawi yaitali kupikisana quality ndi galasi, ndi bwino kudziwika. Ubwino undoubted ndi kuthekera pulasitiki mandala ntchito kupirira zodabwitsa makina - iwo ali zovuta kusiya. Koma pali downside, ndi kuti Mlengi wa mtundu wa Optics si lengezani.

• Pa ntchito, pulasitiki aphimbidwa ndi ming'alu ing'onoing'ono, zimakhalapo.
• M'kupita kwa nthawi, pamwamba pa nkhaniyo ili opunduka ndi mitambo.
• Ngakhale wachibale mtengo wotsika, apamwamba pulasitiki opaleshoni sakhalitsa.

Zogulitsa ndi wabwino ndipo Optics, zopangidwa pulasitiki, zomwe si poipa kwa nthawi yaitali ndipo alibe molakwika fano, koma monga ulamuliro, mankhwala amenewa anapangidwa wopanga kokhaku ndipo pamafunika ndalama.

Galasi magalasi ndi khalidwe la opanga ndi apamwamba zitsanzo pulasitiki. Bwino cholinga galasi transmits fano pa diso 1: 1, ichi ndicho chuma ukulu.

The kuipa magalasi galasi akhoza zimachitika zokha mfundo ziwiri:

• Zinawonongedwa ndi mantha mawotchi.
• A amaposa wa fogging pambuyo kusintha mwadzidzidzi chilengedwe kuchokera ozizira kwa wina ofunda.

Ophthalmologists, kuweluza odwala awo, zokonda zapatsidwa kwa magalasi galasi, monga ngakufunika.

magalasi

Posankha chimango, ambiri woyamba wa zonse kulabadira kapangidwe ndi kalembedwe. Komanso posankha chimango muyenera bwinobwino nkhani lomwe anapanga. chimango The suyenera ndi atolankhani, chifukwa mkwiyo wa khungu, kumene kukhudzana zonse. Chitsanzo akachisi rubberized ndi silikoni septa bwinobwino ndipo adzatsekeredwa kukhala pa mlatho wa mphuno, popanda kuchititsa kuyabwa ndi kuwonongeka kwa khungu.

magalasi amuna ndi diopters

Kulengedwa mafelemu Optics lagawidwa mitundu itatu. Motero, munthu wa mitu wotchuka kwambiri wa opanga ndi magalasi amuna ndi diopters, amene ali okhulupirika wothandizira, osati kunyumba komanso kuntchito. chiwerengero cha kudzinenera wamwamuna ikukhudza ntchito panja mu dzuwa, apa ndi omanga pavers msewu, madalaivala, alimi ndi ena. Ambiri a iwo ndi mavuto masomphenya, kotero maso awo akufunika kwa chitetezo chapadera. Ndi luso lamakono mwayi ntchito ziyangoyango dzuwa magalasi masomphenya pamene galimoto, nthawi zina ndi pa thupi.

Pamene kupopera magalasi ntchito milingo yosiyanasiyana ya tinting ndi machulukidwe zosiyanasiyana ndi luso pochitika kunyezimira kwa dzuwa pa diso. Pali ❖ kuyanika wosanjikiza 4:

• "0" - 20% ya mlingo wa chitetezo mwangozi dzuwa. Mbali - zipinda ofesi ndi malo ndi dzuwa yaing'ono kapena osakhala okhazikika.
• "1" ndi "2" - mulingo woyenera zosinthika ntchito kunyumba. Chitetezo cha maso mwangozi dzuwa pakati pa 20 ndi 80%.
• "3" - osachepera 90% ya chitetezo diso kwa dzuŵa. Njira yoyenera ya ulesi pa gombe.
• "4" - mlingo wamphamvu chitetezo ntchito ndi okwera akatswiri ndi apaulendo mayiko mkulu dzuwa ntchito.

zinthu Photochromic, amene ntchito kuphimba mandala - ichi ndi chimodzi mwa atulukira posachedwapa mu dziko sayansi, amene anaganiza vuto chitetezo diso kwa glare ndi dzuŵa ndi kukonzedwa zina ya masomphenya ndi kuchibweretsa icho kubwerera mwakale kwa anthu ndi kuwonongeka kwa masomphenya.
