Waxa jira laba darajo oo kaliya ee lenska bifocales, kuwaas oo u kala qaybsan iftiinka sare iyo iftiinka hoose.Iftiinka sare iyo midka hoose labaduba waxay noqon karaan myopia, hyperopia, astigmatism, iwm., laakiin iftiinka sare wuu ka qoto dheer yahay iftiinka sare ee myopia iyo qotodheeraanta aragtida fog.

Horumarka waxaa lagu horumariyaa iyadoo lagu salaynayo iftiin labanlaab ah.Ma aha oo kaliya inuu leeyahay sifooyinka iftiinka labajibbaaran, oo ay ku jiraan iftiinka sare iyo iftiinka hoose, laakiin sidoo kale wuxuu leeyahay hab tartiib tartiib ah oo dhexda ah.Darajada u dhaxaysa iftiinka sare iyo iftiinka hoose waa habka isbeddelka tartiib tartiib ah.

Dusha sare, way iska caddahay in la arko farqiga u dhexeeya iftiinka labajibaaran.Waxaa la arki karaa xariiqda qaybinta ama isku xirka iftiinka sare iyo kan hoose, laakiin dusha sare ee lenska horusocodka ah ma arki karo wax farqi ah.

Aagga kala-guurka, ma jirto dhibaato boodi maroodi ah.Taasi waa, si tartiib tartiib ah meel fog ilaa dhow, ka dhow ilaa fog, haddii aysan jirin aag kala guur ah, ka fog ilaa fog, ka fog ilaa dhow, ma jirto wax ka badan oo ka baxsan.
