Yes, but that has been a while ago.
I used to host an online music contest some years ago and I did that without my sunglasses but everyone was like: "Nooooo, why don't you wear your shades anymore?!" so I decided to put them back on.
The actual reason why I wear them goes back to when I did my first stage performances and got bothered by the spotlights. My eyes aren't really good but I figured that with sunglasses I at least was able to see the audience, which usually appeared to be one big black blob from my (and any other artist's) perspective. Ever since it's been my image.
