@pastelbat oh no lol it tends to be correlated with sleep deprivation. I have slept plenty with the sleep mask and not had double vision, and plenty without the sleep mask and still gotten it. my sleep mask has cushioning so it doesn’t press directly on my eyes and it’s pretty loose, too
@pastelbat yeah I think it’s fatigue-related for me, it gets worse when I stare at computer screens for a while but it wears off by itself thankfully
