Kupfeka, kana kusabatanidza lens ne astigmatism - nyaya yega munhu wese. Kusvikira munguva pfupi yapfuura, varwere vane chirwere chakadaro havana mukana wekuona zviri nani pasina kushandisa magirazi. Pakutanga kwaive nemakristeni akaoma maungaruramisa astigmatism, uye makore mashomanana adarika, vashandi vakadzidza nzira yekugadzirisa maziso ekudzivirira. Zvishoma nezvishoma, urongwa hwezvakanaka zvekugadziriswa kweastigmatism nemafungiro ekuwedzera anowedzera, urongwa hwekukanganisa - hupfupiswa. Kunyange zvakadaro, ivo vachiri zvakawanda kwazvo.
Zvinosarudzwa zvekusarudza manotsi emisipiresi yeastigmatism
Pane zviro zvitatu zvakakosha zvekupfeka ma-lens ekubatanidza ma astigmatism:
- Simba rekutevedzana lenzi rekugadzirisa kuonekwa kwakanaka pamwe chete nemirazi, ayo ane lenzi ane mabhodhoro ekugadzirisa astigmatism. Izvi zvinoderedza mutoro mumaziso uye ngozi yezvinetso.
- Soft lens is toric in shape, iyo yakarurama zvose astigmatism uye myopia .
- Ricid toric or spherical lenses iyo inovandudza maonero anooneka uye inofungidzira astigmatism.
Nzira yekutanga ndiyo yakachengeteka uye yakasununguka pameso. Sezvo astigmatism inoshanduka mukutarisa kweziso, hazvina kunaka kugara uchingovhara lenzi uye magirasi anobvisa kukwana uku. Izvi zvinoputika nemusoro wepamusoro uye kuputsa kwemajeri. Tinotenda nekuda kweiyo nzira, isu tinoramba tichiona zvakanaka nekuda kwe lenzi, kunyange patinopa ziso mukana wekuzorora, kubvisa kugadzirisa astigmatism magirasi. Zvinosuruvarisa, iyo nzira haina kunyanya kufarirwa.
Masikirini ekubatanidza akabatana neastigmatism anonyatsonaka pakuti haapindirani nemagadzirirwo emagetsi muziso uye anopa maonero makuru maziso ose. Pamusana pokuti havana kuoma asi hutsinye, kutarisirwa kunofanira kutorwa kuti kuve nechokwadi chekuti lensi inoramba iine nzvimbo yakasimba pane cornea uye haifambi. Kazhinji, mitemo yekupfeka idzi lenzi yakangofanana neyekugadzirwa kwema-lens.
Dambudziko rekugadzira lenzi rinofanira kubviswa usiku. Vane simba rakakura rekuita semastigmatism, asi maziso achada kuzororazve.
Nzira yekusarudza kodzero yekutora lens for astigmatism, inobva pane zvinhu zvakawanda, asi iyo inonyanya kuitika munyaya iyi ndeyekunyaradza kwako. Kunyangwe akabudirira zvikuru kubva kune optical point of view, lenzi inogona kukuvadza kana ichinzwa zvakajeka paziso.
Pros uye Cons
Kana iwe uchiri kukanganisa kana iwe unogona kupfeka mavarai emagetsi e-astigmatism, teerera pane zvakashata zvekuita nenzira iyi:
- unhu hwepamusoro hwekuvandudzwa kwezvirwere zvinokonzera nekuda kwechimiro chisingaenzaniswi che lens;
- kuwedzera myopia nekuda kwekuderera kwekuyerera kweokisijeni kusvika ku cornea;
- mukana wekuchinja chimiro che cornea;
- shandura iyo topography ye cornea, iyo inobatanidza kusarudzwa kwesimba rakakwana rekutsva kwe lens.
Panguva imwe chete, zvakanakira zvinotaura ivo pachavo:
- mukana wekugadzirisa kunyange yakakwirira corneal astigmatism;
- kuchinja kuduku mumunda wekuona;
- optimal binocular vision;
- zvishoma zvishoma kubhaira uye kusvibiswa.
