Well, I quite understand what you think. But as far as I know, since you've got pink eyes, which is quite bad and harmful to your eye health, you'd better limit your sports time to a small scale. And make sure you take medicines on time, also, warm water and good rest is essential for you. Hope you recover as soon as possible, and by the way, just try not to communicate the problem to others.
If you get the pink eyes, you'd better stay at home and not go out because the pink eyes are contagious. You'd better not go out to play basketball which will make you let the pink eyes infect to other people in the public place. You should take the pink eyes more serious and treat it with scientific ways.
Well, in my opinion, you should not go and play basketball when you suffer pink eyes. And generally speaking, pink eye is a common eye infection which occurs in both adults and kids. And also, the infection normally occurs during rainy and wet season. When it occurs, redness and swelling in the eyes can be possible. And at this moment, you need to be careful about your eyes, or it will just be serious. And if you go and play basketball, it will just make your eye be stressed, and sweating may occur too. In that way, it will just make your eye pink infected heavily. So you should avoid it. To treat it, you need to have some cold compresses. And having a good rest is also essential.
