There could be a variety of reasons for a busted blood vessel in the eye. The most common one is, naturally, an injury. This injury need not necessarily be external. Sometimes, an internal injury can also cause a blood vessel to burst in the eye. However, an external injury would be more likely to cause such a problem. If you have impacted your eye with anything such as a flying object, something hard, or even rubbed it vigorously, then you would most likely have had a busted blood vessel. Keep in mind that this can also happen if you got a hard whack on your eye with your eyes closed. You may sometimes experience a certain amount of tenderness in your eye if you have a busted blood vessel. This may or may not last long, and sometimes, people do not even experience it. But your best bet is to soothe your eyes with cool water if you do experience any discomfort. Sometimes, the red mark that would have appeared on the white of your eye would go away, but sometimes, it could also become a lifelong scar. However, the good part is that this kind of a scar is not necessarily unattractive to look at.
Hard and excessive coughing could be responsible for a busted blood vessel in the eye. . If you are faced with uncontrollable coughing, you may bust a blood vessel. Likewise, exerting any kind of excessive pressure can also have a similar result. If you have vomited too hard for your body to absorb the pressure, for example, then too you may be faced with a busted blood vessel. Sometimes, extremely high blood pressure can also cause a blood vessel in the eye to rupture. You need to take care that such things do not happen again, especially if it has already happened once. Soothe and calm your eyes and give them adequate rest by keeping them closed as much as possible when you are faced with this or any other type of eye injury. Please remember that eyes are an integral part of your life and are also the most delicate organ nature has given you. You should be extra careful about how you treat your eyes. This rule should be applied not only in cases of injury but also otherwise. Remember to keep your eyes clean and free of all sorts of infections and dirt and grit.
