Thanks for the reply! I really appreciate it!
An update on the situation: I've tried a few Chrome accessibility extensions; most either don't work due to the dark color scheme or break the site. Right now I've got one that inverses the colors, but it doesn't 100% help (my eyes still hurt, just... less lol) & it's harder to navigate the site due to dividers and whatnot being practically deleted by this extension. Also, seeing as it's inverting the colors, I can't really see any images (at least not without them looking like a nightmare lol)
I'll keep messing with extensions I suppose, but any other solutions would be much appreciated!
