There are different kinds of masks, though since we've all been through a once-in-a-lifetime pandemic, one's thoughts might first turn to surgical or medical masks worn over the nose and mouth when coming across the term "mask".
But there are other masks, and the most important one to scuba divers would be their diving mask, which covers a different part of the face from those other masks.
This funny t-shirt for scuba divers reads "DIVERS | WEARING MASKS BEFORE THEY WERE POPULAR". The slogan is accompanied by an image of a diver's mask (the clear kind that snugly fits over the eyes and nose) along with a snorkel.
