History of abuurka

Shirkadda waxaa markii hore la aasaasay ka soo Germany, John Bausch ee 1853. Waxa uu optics iyo saaxiib ka dib Genri Lomb noqday lamaanahaaga buuxa furay.

ganacsi ayaa soo saarta looxyada caag laga sameeyey, casriga, microscopes, optics sax kala duwan, oo ay ku jiraan ujeedooyin milatari. Tani waxaa fududeeyay lala kaashanayo Carl Zeiss - saaraha ah ee hormuudka ka ah alaabtii indhaha. Shirkadda ayaa ka mid ah soo saarayaasha ugu horeysay ee muraayadaha, soo Air Force ee Maraykanka (Ray-Ban) ahaa.

In 1966, shirkadda heshay liisanka u-soo-saarka iyo ganacsiga ee contact lenses ka qalab biyo-qaadashada hydrophilic. In 1971, ka iibiyey 100 kun oo laba laba Softlens lenses.

Sanadkii 1987, waxaa la helay ogolaansho FDA inay iska iibiso lenses teflonopodobnym dahaarka ka hortagga dhigaalka protein iyo samaynta siku raaxo badan.

Lenses Soflens 66 ayaa noqotay ballaaran oo caan ah, ayaa la sii daayay in ay 90s hore '. Iyo sanadkii 1993, iyada oo afku ka mid ah shirkadaha Laboratories Conoptica iyo polymer Technology, habka oxygen-permeable ugu horeysay ee la saxo aragga. Dhammaadkii qarnigii la soo dhaafay waxaa jiray horumar degdeg ah a farsamada - ayaa la sii daayay malahan Bausch + Lomb Vision daahir ah, oo loogu talagalay Duugga joogto ah.

awoodda wax soo saarka iyo warbaahinta ee shirkadda, shaqaalaha kuwaas oo in ka badan 10 kun oo shaqaale ah oo ku yaalla 25 dal. Xarunta wuxuu ku salaysan yahay in Rochester.

astaamaha ugu muhiimsan ee contact lenses

lenses wuxuu noqon karaa jilicsan oo adag. lenses adag tahay xoog, raagaya, yar waa ka wanaagsan "neefsato", sidaas dheer xirto. Si kastaba ha ahaatee, iyagu waa raaxo yar, bedeli karaan qaabka uu u wilka, yaraynta toosan muuqaal la koob.

The alaabta ugu muhiimsan ee loo isticmaalo soo saaridda ee lenses jilicsan yihiin hydrogel iyo silicone-hydrogel. hydrogel The maraa oxygen ka xun, si muddada ugu badan ee ammaan muraayadan xidhan aan ka badnayn 15 saacadood. Its xad-dhaaf waa ben la hypoxia ee wilka.

On inta jeer ee uu bedelay hab xiriir edbintu la tusay waxay ku kala qaybsan yihiin hal maalin, toddobaadle, bil kasta, afartii biloodba iyo sannadlaha ah. Maalinta ugu nadaafad - u baahan yihiin dayactir lahayn oo waxaa lagu tuuraa isticmaalka ka dib.

xidhashada mode waa maalintii (15 saacadood), sii dheerayn (ilaa 7 maalmood), dabacsan (ilaa 2 maalmood) si joogto ah (30 maalmood) oo nocturnal (loo saxo qaabka wilka iyo inta la hurdo).

design wuxuu noqon karaa spherical, toric iyo multifocal. Myopia iyo hyperopia saxo spherical, astigmatism - toric, da'da hyperopia - lenses multifocal.

Joogitaanka UV-filter indhaha ka shucaaca ilaaliyo.

lenses midab shabahaya ee iris isha iyo oggolaadaan in aad badasho midabka.
