Yeah, having broken blood vessels in our eyes is very uncomfortable and annoy us very much. As to whether the broken blood vessels in eyes are dangerous or not will depend on the breakage of the blood vessels. That is to say, if the blood vessels are broken on the surface of the eyes, then there is no need for you to worry, because you can just leave them alone and take no medication, and then the broken blood vessels will go away be themselves. On the other hand, if you found that your broken blood vessels are so serious that affecting your work and life, I think it will be dangerous for you and your eyes, because if the broken blood vessels will make your eyes get infected and sometimes they will cause your vision loss. Then you had better go to hospital asking the doctor to give you some pills. Pls remember that you cannot take the Pillsbury by yourself, because it has been proven that some pills can cause the broken blood vessels. Thanks.
