Take it easy, a bit of orange juice can not hurt your eyes. And it always happens in our daily life when something splashes into eyes. Remember not to rub your eye when something splashes into your eyes. You just need flush your eye by some clean water, and then have a short time rest. Your eyes will recover only for several minutes.
It is not a big problem, just wash your eyes with clean water immediately. It will be fine. But you shall take it serious, or it may irritates. If it still hurts tomorrow, you are suggested to take a comprehensive eye check. Then consult your doctor, also ask some prescribed medicine to help you. Wish you will be OK soon.
Well, from what you said, I know that you might have gotten some irritative reactions from getting some juice into your eyes. Because those orange juice is highly irritative and acid stuff, which might lead to some discomfort to you. What I recommend right now to you is to get some normal saline to flush your eyes, then get some antibiotic eye drops to help with your eyes. Just try to be more careful in the future.
