combigan eye drops

I have used Lumigan for three months now and it is still irritatating and the whites of my eyes are always red. I also have more glare as I feel the drops leave an oil coat on and it distorts my vision. Also, I can't sleep as well and therefore can't focus doing work. My eyelids feel heavy and tired and I seem to want to nap. I also started using combigan for two months now.

PS this is my first blog.
