Clear Vision
Water and air refract light in different ways, and our eyes are evolved to focus in air. Thus, our vision underwater becomes fuzzy and unfocused. A snorkeling mask creates a pocket of air that allows the eyes to focus normally.
Protection
Much like goggles, a snorkeling mask will offer some protection to the eyes and prevent irritation from saltwater exposure.
Equalization
If a snorkeler decides to dive down to have a brief-but-closer look at something, the nose piece in the mask allows them to put a little extra air in the mask to equalize against the underwater pressure. This is impossible with goggles.
Firm Fit
Snorkel masks are better than swim goggles for seeing things underwater in open water conditions because they have a firmer fit on the face and are less likely to be knocked off. Also, they are less prone to leakage.
Range of Vision
Snorkel masks offer a greater range of vision than goggles, because they are usually made with panels that permit at least some peripheral vision.
Snorkel Clip
Finally, snorkels are made to be clipped onto the heavy-duty straps of a snorkel mask, so the mask serves as a convenient mounting point. Goggles, with their flimsy rubber-band strap, cannot be used as a substitute.
