SETO 1.74 lens hal aragga ah ee SHMC Sawirka leh

Sharaxaad Gaaban:

Muraayadaha aragga kaliya waxay leeyihiin hal dawo oo keliya oo loogu talagalay aragti-fogaanshaha, aragga dhow, ama astigmatism.

Inta badan muraayadaha dhakhtarku qoro iyo muraayadaha akhriska waxay leeyihiin lenses-arag keliya.

Dadka qaar ayaa awood u leh inay u isticmaalaan muraayadaha aragga kaliya ee fog iyo kuwa dhowba, iyadoo ku xidhan nooca daawada loo qoray.

Lens-yada hal-aragga ee dadka fog-fog ayaa ka dhumuc weyn xarunta.Muraayadaha aragga kaliya ee loogu talagalay dadka gashan ee leh aragti dhow ayaa ka dhumuc weyn geesaha.

Muraayadaha aragga kaliya waxay guud ahaan u dhexeeyaan 3-4mm oo dhumucdiisuna tahay.Dhumucdiisu way kala duwan tahay iyadoo ku xidhan cabbirka jir iyo muraayadda la doortay.

Tilmaamaha Alaabta

1.Sidee lensyada-tusaha sare uga duwan yihiin muraayadaha caadiga ah?
Marka tusmada dib-u-soo-celinta ay korodho, qalooca loo baahan yahay si loo soo saaro sixid gaar ah ayaa hoos u dhacaya.Natiijadu waa faan, soo jiidasho badan, mug hoose, muraayad khafiif ah oo ka yar sidii hore ee suurtogalka ahayd.
Qalabka tusmada sare waxay siiyeen bukaanada, gaar ahaan kuwa leh khaladaad weyn oo dib u habeyn ah, xoriyad ay ku doortaan cabbirka muraayadaha iyo qaababka, iyo sidoo kale qaababka jireed, kuwaas oo aan mar keliya heli karin.
Marka qalabkan muraayada tusmada sare loo isticmaalo naqshadaha aspheric, atoric ama horusocod leh oo lagu lammaaniyo daawaynta lenska qaaliga ah, qiimaha adiga, bukaanku, aad ayuu u balaadhiyaa.

2.Waa maxay khaladaadka dib-u-soo-celinta ee muraayadaha aragga ee kali ah sixi karaan?
Muraayadaha hal-araggu waxay sixi karaan khaladaadka ugu caansan:
① Myopia
Myopia waxaa loola jeedaa aragga dhow.Walxaha fogaa way adkaan kartaa in si cad loo arko.Muraayadaha fogaanta aragga oo keliya ayaa ku caawin kara.
②Hyperopia
Hyperopia waxaa loola jeedaa aragtida fog.Walxaha kuu dhow way adkaan kartaa in si cad loo arko.Muraayadaha akhriska aragga kaliya ayaa ku caawin kara.
③Presbyopia
Presbyopia waxaa loola jeedaa luminta aragga dhow da'da awgeed.Walxaha kuu dhow way adkaan kartaa in si cad loo arko.Muraayadaha akhriska aragga kaliya ayaa ku caawin kara.
④Astigmatism
Astigmatism waa xaalad ka dhigaysa arag qalloocan masaafo kasta sababtoo ah qalooca isha ee asymmetric.Labada muraayadaha wax-akhriska ee hal aragga ah iyo muraayadaha fogaanta aragga ee hal aragga labaduba waxay kaa caawin karaan inaad gaadho aragti cad.

3. Doorashada dahaarka?

Sida 1.74 lens index sare, daahan super hydrophobic ayaa ah doorashada kaliya ee daahan.
Daahan Super hydrophobic sidoo kale magaca daahan crazil, ka dhigi kara muraayadaha biyuhu, antistatic, silbasho anti iyo iska caabin saliid.
Guud ahaan, daahan super hydrophobic jiri kara 6 ~ 12 bilood.
