I need help/advice on my eyes. I have this problem where all of a sudden half my eye would be red as if irritated (like the veins and everything). Like from the circle part and so on pretty much replacing the white area in the eye. Its not pinkeye because after some time it goes away and then weeks or a few months later it comes back (usually not in the same area though). Like in the other side/eye. I wear contacts but their not due for a change (since I get a notification of when to change them). I don't really have allergies, but is it possible that, that could be it? Or is it something else? I've tried putting some cold water on a pad and it helps a bit, making it less red-but more like a pinky-but it also stings since my mom says that its because its irritated.
I just want to know why do I keep having this and what can I do about it? Also if I need medical help or something of the sort. Please help!

 

This sounds like a problem that needs to be addressed by a doctor. Is sounds like you might have something wrong that needs medical attention. You probably need a special type of eye drops or a different brand of contacts. I might also be possible that you have an allergy as you suggested. You need to see a doctor next time this happens so he/she can evaluate it.
