I have a whole collection of dive masks from over 50 years of diving. Yes, visibility is a problem, and it was addressed in the 1970s with three-window masks. One of my favorites is the Farallon three-window mask, and you can see two versions of it in this photo, bottom left two masks (one marked “White Stag,” but it was a silicone version of the Farallon mask.

One of my favorite masks of all time is this three-window mask by Scubapro. You can see one of the versions in the above photo, top row on the left. Silicone masks are not only semi-transparent, but will last a lifetime. This one is in silicone, with an older front glass piece without the purge valve (I took it off an earlier neoprene Scubapro mask that literally melted off my face), and put it into the silicone version. Even with the nose purge, it has excellent visibility.

Here’s some more of my collection. Note that there are a number of the old, oval masks. These have excellent up and down vision, but not so much side vision. There is a Dacor 3-window mask in the bottom row, and the Scubapro mask with the nose purge is there too.

Right now, mask prices are sky-high, and I would not buy a new one. I‘d go on-line to E-Bay and see what I could find, then take it apart and give it a good scrubbing before using it (this can only be done with older masks with metal rims). Here is a Scubapro mask of a type I’ve used (but in a Dacor version), which would fit the bill:

PS, ignore those who are telling you that you lack something or another (awareness, etc.). It is a problem with visibility.
