Anyone have any thoughts or experiences with using a sign language as someone with eye contact avoidance?

cross-posted from: https://hexbear.net/post/3081907 and https://hexbear.net/post/3076602

For instance, did it go OK to wear sunglasses indoors; or did the eye contact avoidance disappear when using the sign language, only to reappear when using a spoken language; things like that.

Didn't get any responses the previous two times I asked, so I might as well ask one last time.
