I had redness in my eyes foe few days, which appeared and disappeared on its own, but used to be severe when i used contact lenses;my vision however was fine. I had a similar problem earlier as well and so i used the medication prescribed by my doc earlier. the medication included homide eye drops which I was told causes blurriness of vision. I used it along with other eye drops for 2 days thrice a day. the redness was gone but irritation persisted, so i went to my doc , he said the the medication i took was fine but that this time's infection was milder than the previous one. So he prescribed me Saptob F and Zoneph eye drops and 4Quin ointment. the redness and irritation is all fine but the blurriness of vision is persisting. I used Homide on Sunday and monday, and followed doctor's new prescription from Tuesday. It is Thursday now, so is the blurriness the continued effect of homide or the new drops or anything serious? For how long does the effect of homide last?
