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.

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.
2) Waa maxay muraayadda sawir-qaadista?
Lenses Photochromic waxaa sidoo kale loo yaqaan "lenses sawir leh".Marka loo eego mabda'a falcelinta dib-u-celinta ee beddelka midabka iftiinka, muraayaddu waxay si dhakhso ah u madoobaataa iftiinka iyo shucaaca ultraviolet, xannibi iftiinka xoogga leh oo nuugaya iftiinka ultraviolet, oo muujiya nuugista dhexdhexaadka ah iftiinka muuqda.Dib ugu noqo mugdiga, waxay si dhakhso ah u soo celin kartaa xaalad hufan oo aan midab lahayn, hubi gudbinta muraayadda.Markaa muraayadaha midabka beddela waxay ku habboon yihiin isticmaalka gudaha iyo dibaddaba isku mar, si looga hortago iftiinka qorraxda, iftiinka ultraviolet, dhaldhalaalka dhaawaca indhaha.Marka loo eego mabda'a falcelinta dib-u-celinta ee beddelka midabka iftiinka, muraayaddu waxay si dhakhso ah u madoobaataa iftiinka iyo shucaaca ultraviolet, xannibi iftiinka xoogga leh oo nuugaya iftiinka ultraviolet, oo muujiya nuugista dhexdhexaadka ah iftiinka muuqda.Dib ugu noqo mugdiga, waxay si dhakhso ah u soo celin kartaa xaalad hufan oo aan midab lahayn, hubi gudbinta muraayadda.Markaa muraayadaha midabka beddela waxay ku habboon yihiin isticmaalka gudaha iyo dibaddaba isku mar, si looga hortago iftiinka qorraxda, iftiinka ultraviolet, dhaldhalaalka dhaawaca isha.
3) Waa maxay faraqa u dhexeeya HC, HMC iyo SHC?
| Dahaarka adag | Daahan AR / Daahan badan oo adag | daahan Super hydrophobic |
| waxay ka dhigtaa muraayadda aan dahaadhka ahayn mid adag oo kordhisa iska caabbinta nabarrada | waxay kordhisaa gudbinta muraayadda waxayna yaraynaysaa milicsiga dusha sare | muraayada waxay ka dhigtaa mid aan biyuhu ahayn, antistatic, silbasho lid ku ah iyo caabbinta saliidda |
