Waa maxay muraayadaha horusocod ee dadka waaweyn?

Muraayadaha aan guud ahaan xidhno waa muraayadaha monofocal caadiga ah, kuwaas oo kaliya arki kara meel fog ama dhow.Dhanka kale, muraayadaha horusocodka ee dadka waaweyni waxay leeyihiin meelo badan oo udub dhexaad ah, iyada oo qaybta sare ee muraayadda loo isticmaalo aragga fog iyo qaybta hoose ee loo isticmaalo aragtida dhow.Waxaa jira isbeddel tartiib ah oo laga bilaabo awoodda fogaanta ee ka sarreysa muraayadda ilaa awoodda dhow ee ka hooseeya muraayadda iyada oo loo marayo isbeddel tartiib tartiib ah ee awoodda dib u celinta.
Muraayadaha horusocod mararka qaarkood waxaa loogu yeeraa "no-line bifocals" sababtoo ah ma haystaan ​​xariiqdan bifocal ee muuqata.Laakin lenses horusocod leh ayaa leh nashqad dhinacyo badan leh oo aad uga horumarsan marka loo eego bifocals ama trifocals.
Muraayadaha horusocodka leh ee mudnaanta leh (sida muraayadaha Varilux) waxay badanaa bixiyaan raaxada iyo waxqabadka ugu fiican, laakiin waxaa jira noocyo kale oo badan sidoo kale.Xirfadlaha daryeelka indhahaaga ayaa kaala hadli kara sifooyinka iyo faa'iidooyinka muraayadaha horusocod ee ugu dambeeyay oo kaa caawin doona inaad hesho muraayadaha ugu fiican ee baahiyahaaga gaarka ah.

Awoodda muraayadaha horusocodku waxay si tartiib tartiib ah isu beddelaan min dhibic ilaa bar dusha muraayadda, iyagoo siinaya awoodda muraayadda saxda ah
in aad si cad u aragto walxaha masaafo kasta.
Bifocals, dhanka kale, waxay leeyihiin laba awood oo lens oo keliya - mid si cad loogu arko walxaha fog iyo awoodda labaad ee hoose
kala badh muraayadda si aad si cad ugu aragto masaafo akhris oo cayiman.Isku xirka aagagga tamarta ee kala duwan
waxaa lagu qeexay "xariiq laba-geesood" oo muuqda oo gooya bartamaha muraayadda.

Faa'iidooyinka muraayadaha horumarka leh

Lenses horusocod ah, dhinaca kale, waxay leeyihiin awood badan oo muraayado ah marka loo eego bifocals ama trifocals, waxaana jira isbeddel tartiib ah oo awoodda ah min dhibic ilaa bar oo dhan oogada muraayadda.

Naqshadeynta lenses-ka-horusocodka leh ee lenses-ka ah ayaa bixiya faa'iidooyinkan muhiimka ah:

* Waxay bixisaa aragti cad dhammaan masaafada (halkii ay ka ahaan lahayd laba ama saddex masaafo kala duwan oo daawasho ah).

* Waxay meesha ka saartaa dhibka "boodboodka sawirka" ee ay sababaan bifocals iyo trifocals.Tani waa halka walxaha si lama filaan ah ugu beddelaan cad iyo booska muuqda marka indhahaagu ay ka gudbaan xariiqyada muuqda ee muraayadahan.

* Sababtoo ah ma jiraan "xariiqo labajibbaaran" oo muuqda oo ku jira muraayadaha horumarka, waxay ku siinayaan muuqaal dhalinyaro ah oo ka badan bifocals ama trifocals.(Sababtan oo keliya ayaa laga yaabaa inay tahay sababta ay dad badani maanta u xidhaan muraayadaha horumarka leh marka loo eego tirada xidhan bifocal iyo trifocals oo la isku daray.)
