Pretty much what it says on the title. The new blurple is much too bright for my eyes and hurts to look at, speaking as someone who keeps most of his colours pretty desaturated. The saturation slider in discord options isn't a solution as it makes every other colour besides the blurple also look really desaturated, which is an issue because it makes those colours look really really bad.
The blurple from before the changes was easy on the eyes and pleasing to look at, but now I have to avoid actively looking at it as much as possible. Bright isn't necessarily better for people who's eyes can't handle it.
