Ndeipi lenzi yakanaka pakuverenga magirazi?
1. Mumamiriro ezvinhu akajairwa, magirazi ekuverenga anofanirwa kugadzirwa nesimbi, nekuti chete mafirimu echiratidziro echinhu ichi achange ari nani pane ayo ezvakajairwa zvinhu, ane simba rinopesana necorrosion uye simba rinopikisa Kakawanda, iyo furemu zvinhu zvinoshandiswa hazvigone kuve. zvakasarudzwa kubva kune zvinhu zvinosangana neganda, kana zvisina kudaro iwe uchanzwa kusagadzikana zvakanyanya paunenge uchipfeka, kunyanya magirazi ekuverenga akagadzirirwa vakwegura, uye miviri yevakwegura inenge iduku.Vanhu vanonyanya kusimba, saka pakusarudza zvinhu, unofanira kusarudza zvinhu zvisiri allergic kune ganda, zvikasadaro mhedzisiro ichava yakaipa.
2. Mukuwedzera, iyo lens yekuverenga magirazi inonyanya kugadzirwa neresin.Ichi chinyorwa chinogona kurwisa ultraviolet, infrared, nezvimwe zvinhu.Kana yakapfekwa, ichavawo nehumwe dhigirii rekudzivirira kuneta kumaziso ako, kana zvisina kudaro ichaita Mushure mekuishandisa kwechinguva, ichabudisa imwe pfungwa yekuneta, uye kunyange kana hutano husina kunaka, zvimwe zvirwere zvinogona kuitika.Mushure mezvo, hapana nzira yekuibata nayo.Naizvozvo, iyo resin lens iri nani pane yakajairika lens.Iyo refractive index zvakare yakakwira zvakanyanya.
3. Paunosarudza lens, unofanira kuwedzera firimu kune lens, kana kushandisa aspherical lens.Iyi sarudzo yakanaka chaizvo, iri nani pane akajairwa lenzi.Mukuwedzera, inogona kuita kuti munda wako wekuona ujeke., Pachange pasina zvipingamupinyi pakuverenga kana mamwe mabasa.Hapazovi nedzungu repfungwa.
Maitiro ekufananidza magirazi ekuverenga
1. Vamwe vanhu vakwegura vanoda kuchengetedza dambudziko uye kutenga magirazi ekuverenga pachitoro chemaziso kana mumugwagwa.Izvi zvakaipa.Nokuti magirazi ekuverenga anotengwa zvakananga kazhinji ane dhigirii rimwe chete rekuona, asi maziso evanhu vose vane mamiriro akasiyana-siyana akadai se myopia, hyperopia, astigmatism, uye dhigirii ye presbyopia yemaziso evanhu zvechokwadi yakasiyana, uye kureba kwe interpupillary kwakasiyanawo.Kana iwe ukaipfeka zvakasununguka Inogona kukonzera kukanganisa kukuru kumaziso, uye zviri nyore kuwedzera kushushikana, kuneta, kusaona uye zvimwe zviratidzo.Unofanira kutanga waenda kuchipatara ophthalmology ongororo ziso kuti abvise cataracts, glaucoma, uye fundus zvirwere nezvimwe zvirwere fundus, uye ipapo kumbira chiremba kuwana refraction uye kuona interpupillary chinhambwe;ita kuti presbyopia lens uye dhigirii rekugadzirisa zviratidzo rienderane.
2. Vakwegura vanofanira kuedza magirazi kwechinguva pashure pokunge aiswa.Izvo zvakakoshawo kuziva kuti nguva yekuongorora yakati rebei.Mushure mekupfeka magirazi ekuverenga kwenguva yakati, kana iwe uchinzwa kuti magirazi haakodzeri, unogona refraction kuti utarise shanduko mukuona kwepedyo uye sarudzazve magirazi.Teerera kune mwero weziso, zvikasadaro zvinowedzera kushushikana kwemaziso uye nekumhanyisa presbyopia.
3. Chiyero che presbyopia mumaziso evakwegura hachina kumira.Mushure mokunge magirazi akaiswa, maonero avo anofanira kuongororwa nguva dzose makore maviri kusvika matatu;dhigirii rema lens rinofanira kugadziriswa munguva maererano nekuchinja kwechiratidzo.Kana pasina zviratidzo zvakadai sekukanganiswa kwefonti, dzungu uye kurutsa, zvinoreva kuti magirazi ekuverenga akakodzera;kana maziso akaneta mushure mekuverenga kwenguva yakareba, zvinoreva kuti simba rinofanira kugadziriswa.
4. Paunosarudza chimiro chemutambo, unofanirwa kubhadhara kune ruvara rwaunoda.Inogona kuratidza kukomba uye chiremera chevakwegura pamwe chete nechimiro chevakwegura.Kune akawanda mavara echimiro, akadai se: muraraungu ruvara;ruvara rwekofi;pearly white and white.Iyo furemu inofanira kusarudzwa nekuoma kwakanaka;ine simba rekuramba kukotama.Huremu huremu huremu hunogona kutariswa nevakura maererano nezvavanofarira.
Kusanzwisisana nemagirazi ekuverenga
1. Hazvina kunaka kuva nemufananidzo wakachipa uye wakajeka.Magirazi ekuverenga mumugwagwa kazhinji ane chiyero chakafanana chemaziso uye chinhambwe che interpupillary.Nekudaro, vanhu vazhinji vakura vane zvikanganiso zve refractive senge myopia, hyperopia kana astigmatism.Uyezve, chiyero chekuchembera kwemaziso chakasiyana, uye kureba kwe interpupillary kwakasiyanawo.Kana iwe ukangopfeka magirazi egirazi, hazvisi izvo chete hazvizokwanisi kuita zvakanakisa zvinoonekwa kune vakwegura, asi zvinokonzeresa kukanganisa kwekuona uye kuneta kwemaziso.
2. Fit magirazi pasina optometry kana kuongorora.Usati wapfeka magirazi ekuverenga, enda kuchipatara kunoongororwa zvakadzama maziso, kusanganisira kuona kure, kuona pedyo, intraocular pressure uye fundus kuongororwa.Cataracts, glaucoma, uye zvimwe zvirwere zve fundus zvinofanirwa kubvisirwa kunze optometry isati yaona dhigirii.
3. Kana magirazi ekuverenga akapfeka kusvika kumagumo, dhigirii ye presbyopia ichawedzera nekuwedzera kwezera.Kana imwe nguva magirazi ekuverenga asina kukodzera, anofanira kuchinjwa nenguva, kana zvisina kudaro achaunza kukanganisa kwakawanda kuhupenyu hwevakwegura, uye ichawedzera dhigirii ye presbyopia.Panguva imwecheteyo, lenzi dzepresbyopic dzine hupenyu hushoma.Kana iyo yakashandiswa kwenguva yakareba, ma lens achatambura nekukwenya uye kuchembera, izvo zvinoderedza kuwanda kwekupfuura kwechiedza uye kukanganisa kunaka kwekufungidzira kwema lens.
4. Girazi rinokudza rinotsiva presbyopia.Vanhu vakwegura vanowanzoshandisa magirazi ekukudza panzvimbo pemagirazi ekuverenga.Girazi rekukudza rakapetwa mumagirazi ekuverenga rakaenzana ne1000-2000 madhigirii.Kwenguva yakareba "kupinza" maziso, zvichange zvakaoma kuwana dhigirii yakarurama apo magirazi ekuverenga anofananidzwa.Kupfeka magirazi ekuverenga kunogona kungoshandiswa kutarisa zvinhu zviri pedyo.Kufamba nemagirazi ekuverenga kana kutarisa kure kuchaita kuti chiono chisajeka uye chiite dzungu.Kupfeka magirazi ekuverenga kunofanirwa kuenda kuburikidza nekutarisa kwakasimba kwekuona, nekuti kutenga peya yekuverenga magirazi kunogona kukonzera kusagadzikana kupfeka uye kuwedzera kwe presbyopia nekuda kweiyo parameter isiriyo.
