it happens to me too, i dont think there is a way to fix this. For me drinking water regularly while playing and getting better ventilation in my room helped a bit
Yeahh that happens with me quite often
Ig it is due to eye strains and high pressure while playing, like I get that feeling whenever I play comp, but not if I play spike rush or with friends
I would suggest take good breaks after every hour and wash your face after u get up!
