My right eye is red and it doesn't hurt/itch/burn. Why?

My right eye has been red since morning. I wear contact lens and I do NOT remember if it was red before i put it on. It's now at night, and I've only worn for 8 hours. The red is not very like RED RED RED it's like very light, it doesn't look bad at all, it's just I don't Lol. I doesn't irritate me, it doesn't hurt, burn, itch or anything. If i don't lookm in the mirror, I wouldn't even know that it's red. I have no problems opening or closing my eyes, it doesnt tear or anything.

I've taken out my contacts and put so drops, but… Nothing's happening (it's been like 15 minutes since I did tht)

Have the same problem sometimes. Dont worry. It goes away.

It could be a small bacteria infection. I would take the lenses out and wear your glasses for a day or so. It can also be the start of pink eye, so wash your hands a lot.
I hope this helps and it gets better soon.
