I also needed bifocal lens added, so I could read my computer. I first bought the DGX bifocal goggle which is decent goggle at a great price. The bifocal diopter I ultimately needed was not offered in the DGX google, so I had to look elsewhere. I then found the TUSA CEOS google which sells with additional lens with bifocal lenses glued to them with the diopter I wanted. Actually I only put the bifocal lens in my left eye, which I’ve been very happy with.
FYI: When I bought my TUSA google at my local dive shop they had several bifocal lens and offered to swap out lens until I got my desired diopter strength.
