Should I fight even though im half blind?

For a few years now i have been legally blind in one of my eyes. I cannot see things in the middle of that eye but i still can see everything around it. Its like a blotch in the middle of my eye. My other eye has perfect vision. On thop of that when both eyes are open i can even tell there is a problem. The only time i notice the blotch is if my other eye is closed. I have trained in MMA for a few years now and i want to compete. I love the sport a lot, but im wondering if its worth the risk of losing vision in my other eye. What do you all think?
