Why did AMC in this location stopped 3D and IMAX 3d movies ????

Health reasons I'm guessing

IMAX yes, 3d unfortunately not

I think they stopped 3D because you typically recycle the glasses at the end of the movie and they would have to sanitize the glasses for next use. With covid, it probably isn't worth the cost to sanitize the glasses to whatever the guidelines mandate. I also think regular IMAX and Dolby are more popular premium formats than 3D showings. Personally, I get headaches with 3D, so I normally choose Dolby for an enhanced theatre experience.
