This used to happen to me quite often
It is caused by very dry eyes
I have tried βArtificial Tearsβ which does make you feel better for a little while but can be addictive and itβs not the best solution
What you can do to naturally decrease the dryness is blink and yawn more often, youβd be surprised
If you are spending a lot of time in front of the computer, thatβs probably the cause, in this case, you can download Iris
It will reduce PWM Flicker and Blue Light, make some magic, and make you feel better in no time
