do your eyes get or feel dry? is your eye distance set correctly on the lenses?
do you spend a lot of time in front of a screen, be it computer or other devices?
do you struggle making out shapes on the headset display?
do you have any indicators that you might have bad eye sight?
make sure that you have a bottle of water nearby so that you can stay hydrated while playing and your eyes have the water they need to keep them moist
if you suspect that you have bad eye sight go get it checked and consider buying vroptician lenses if you only need it for the headset
if you spend a lot of time in front of screens, try to take breaks and look out the window into the distance so that your eyes can adjust to something else
also if the screen is too bright for you use night mode when the sun goes down and turn down the brightness
