Tilmaamaha Alaabta

1) Waa maxay muraayadaha bifocal?

Bifocals waa muraayado leh laba awoodood oo sixid oo kala duwan.Bifocals waxaa badanaa lagu qoraa presbyopes
kaas oo u baahan in la saxo myopia (aragti dhow) ama hyperopia (aragti fogaansho) oo leh ama aan lahayn sixid loogu talagalay astigmatism (aragti qalloocan taasoo ka dhalatay lens qaabaysan ama kornea).Ujeedada ugu muhiimsan ee lenska laba-geesoodka ah waa in la bixiyo dheelitirka diiradda u dhexeeya fogaanta iyo aragtida dhow.
Guud ahaan, waxaad eegaysaa oo aad eegaysaa qaybta fogaanta ee muraayadda marka aad diiradda saarayso dhibcaha ka fog, adiguna
hoos u eeg oo u dhex mara qaybta laba-geesoodka ah ee muraayadda marka aad diiradda saarayso akhrinta walxaha ama walxaha gudaha 18
Inciish oo indhahaaga ah. Guud ahaan waa la aqbalay in Benjamin Franklin uu hindisay bifocal-ka.Bifocal-ka ugu caansan maanta waa 28-ka Toosan ee Bifocal kaas oo leh xariiq toosan oo ku yaal xagga sare oo leh 28mm dhexroor.Waxaa jira dhowr nooc oo bifocals sare toosan oo la heli karo maanta oo ay ku jiraan: Toosan Top 25, Toosan Top 35, Toosan Top 45 iyo Fulinta (Franklin Seg asalka ah) kaas oo maamula ballaca dhamaystiran ee lenska.
Marka lagu daro bifocals sare ee tooska ah waxaa jira gebi ahaanba wareegyo wareeg ah oo ay ku jiraan Wareegga 22, Wareegga 24, Wareegga 25
iyo Isku-dhafka Wareegga 28 (qayb qeexan oo aan lahayn).
Faa'iidada qaybta wareega ayaa ah in ay yar tahay boodboodka sawirka marka mid ka soo wareego masaafada ilaa qaybta dhow ee muraayadda.
