Prevention of eye infection. Me through.

So, it's second time in this year that I'm dealing with a kind of bacterial eye infection. My eyelids got very itchy and won't stop until I rub them with my fingers. I know that's a bad habbit but can't help it. Plus, whenever I splash water on my eyes to remove eye-dust, itching started again. First it occurred in March and after that now. Then a doctor prescribed me two eye drops - Apdrops and a Lubrex eye drop. But there's a catch, I can't apply water on my eyes while using these drops. Now this is creating quite a problem while bathing. I just don't want to repeat these pattern next time after the problem ends. So can you suggest me some remedies to save my eyes from these bacterial infections. It's so annoying. Kindly guide me through.
