Hey, dont do that. Thats damaging your eye. It may not affect your vision, but your eyes are super soft and squishy, you can do damage if you rub or press on them to the point of color visualizations. Yes, even the amazing deep knuckle rubbing eye scrub, is bad for you. Still happens, but yeah, dont do that.
You should go see a doctor if you have that much pain or strain. Your vision likely isnt as good as you think.
