Well, in my opinion, optic neuritis can just lead to bloodshot eyes. So you just need to be careful about it. Generally speaking, the optic nerve, which is also known as cranial nerve, is a nerve which is present in the retina of the eyes and consists of axons or nerve tracts. Of course, you should know that the main function of the optic nerve is to transmit visual information to the brain. According to some researches, when the optic nerves become inflamed due to any reaction or infection, optic neuritis can be possible. And when optic neuritis occurs, there will have many different eye problems. For example, your eyes will be red and bloodshot, because of the high eye pressure. For your situation, of course, you should go and see the eye doctor, so that he can just give you some advices to treat it. Also, one of the major symptoms of optic neuritis is loss of vision, which may vary from blurring, to complete blindness.
