1.49 CR39 Muraayada muraayada ee dhammaatay ee banaan
Muxuu Samayn Karaa Muraayada Lens-ka ee Madhan?
Unugyada wax soo saarka muraayadaha muraayadaha kuwaas oo u beddela muraayadaha badh-dhammeedka muraayadaha la dhammeeyey iyadoo loo eegayo sifooyinka saxda ah ee warqadda dhakhtarku qoray.
Shaqada hagaajinta ee shaybaarada ayaa noo suurta galinaysa inaan bixino kala duwanaansho balaadhan oo ah isku dhafka indhaha ee baahiyaha xirayaasha, gaar ahaan marka la eego hagaajinta presbyopia. Shaybaarada ayaa mas'uul ka ah inay dusha sare ka saaraan (shiilid iyo turxaan bixin) iyo dahaarka (midabaynta, xoqidda, lidka-milicsiga, ka-hortagga-smudge iwm) muraayadaha.
Waa maxay sababta loo doorto muraayadaha indhaha ee CR-39?
Crystal Vision (CR) waa muraayado tayo sare leh oo ay samaysay mid ka mid ah shirkadaha muraayadaha aduunka ugu wayn.
CR-39, ama allyl diglycol carbonate (ADC), waa polymer caag ah oo caadi ahaan loo isticmaalo soo saarista muraayadaha muraayadaha indhaha.
Soo gaabinta waxay u taagan tahay "Columbia Resin #39", kaas oo ahaa qaacidada 39-aad ee balaastiig heerkulbeeg ah oo uu sameeyay mashruuca Columbia Resins 1940kii.
Waxaa iska leh PPG, maaddadan ayaa wax ka beddelaysa samaynta muraayadaha.
Kala badh sida muraayadda oo kale, aad bay u yar tahay inay burburto, iyo tayada indhaha oo ku dhow inay u wanaagsan tahay sida muraayadda.
CR-39 waa la kululeeyaa oo lagu shubaa moodooyinka muraayadaha tayada leh - la qabsashada tayada muraayadda si aad u dhow.
a) Dhaqaale
b) Iftiin
c) U adkaysta burburka
d) Waa la madoobayn karaa &
e) Ilaalinta UV
Waa maxay muraayadda qaabka xorta ah?
Muraayada qaabka xorta ah ayaa caadiyan leh oogada hore oo wareegsan iyo mid adag, oogada dambe ee saddex-geesoodka ah taas oo ku daraysa warqadda bukaanka. Marka laga hadlayo leniska horusocodka qaabaysan ee xorta ah, joomatari oogada dambe waxa ku jira nakhshad horusocod ah.
Habka freeformku waxa uu isticmaalaa lenses wareegsan oo dhammays tiran kuwaas oo si diyaar ah loogu heli karo qaloocyo sal balaadhan oo kala duwan. Muraayadahan ayaa si sax ah loogu farsameeyay dhinaca dambe iyadoo la isticmaalayo qalab casri ah oo soo saarista iyo nadiifinta si loo abuuro dusha saxda ah ee daawada.
• oogada hore waa mid wareegsan oo fudud
• oogada dambe waa sagxadda saddex-geesoodka ah oo adag
Tignoolajiyada muraayadaha qaabka xorta ah
Waxay bixisaa dabacsanaan si ay u bixiso noocyo kala duwan oo badeecooyin heer sare ah, xitaa shaybaarka indhaha ee yar
• Kaliya waxay u baahan tahay kayd qaybo dhammays-tiran oo shay kasta ah oo ka yimid ilo tayo leh
• Maareynta shaybaadhka waxaa lagu fududeeyay SKU-yo aad u yar
• Oogada horumarsan waxay u dhowdahay isha - oo bixisa muuqaalo ballaadhan oo ku yaal marinka iyo aagga wax akhriska
• Waxay si sax ah u soo saartaa naqshadda horumarka ee loogu talagalay
Saxnaanta daawadu kuma koobna tillaabooyinka qalabaynta ee laga helayo shaybaadhka
Si sax ah u qorida daawada waa la dammaanad qaaday
