Hello. Today I was playing singles with my friend and I noticed that in about midle of our game I started to misshit a lot. I had this issue before but never thought that it is related to something else than myself. But today I thought that this could be related to me sweating really bad. Sweat gets into the eyes and it makes my vision blured/worse than normal. Could this be the case? Did someone of You had this issue? Would headband help me?
