Lens multifocal horumarsan
Miyuu lens-ka-fiirsasho badan yahay, oo korka kor ilaa hoos u qallooca muraayadda ka hor inta aanu si joogto ah u kordhin, awoodda wax-soo-celinta ee degmadu waxay ku taallaa qaybta sare ee muraayadda waa mid aad u fog, si tartiib tartiib ah, u kordheysa si joogto ah, ilaa ku dhawaad hoosta muraayadda oo leh aag. waxay gaadheen nambarkii ku dhawaaday diopter, laba muraayadood ayaa arki kara, masaafada ayaa arki karta mar kale meel u dhow, waxaad sidoo kale arki kartaa fogaanta shayga. Muraayadaha horumarka leh waxa lagu tilmaamaa inay yihiin “lenses zoom,” iyo laba muraayadood ayaa loo isticmaali karaa sidii lammaane dheeraad ah. Tusaale ahaan, way ku habboon tahay ardaydu inay wax akhriyaan oo qoraan ardaydu waxay isticmaalaan muraayadda (la kulan eegno sabuuradda, akhri buugaagta, shaqada guriga iyo baahida kale ee muuqaalka), oo ku habboon dadka cad-cad ee caabbinta daalka ee muraayadda (si ay ula qabsadaan fog, dhexda iyo meel u dhow muuqaalka, fududahay in la shaqeeyo), laqabsiga dadka da'da dhexe iyo da'da weyn d lenses horusocod u fiicneyn (dusha qaloocsan oo bilaash ah, si fiican, dhexdhexaad ah, u dhow in la beddelo, ma dawakhsan maskaxda balaadhi).
