Scuba masks come in all shapes, sizes, colors and styles. But one choice you may be faced with when choosing your next mask is should I go for two frames or one? While the comfort and fit of a mask is the most essential, finding an aesthetically pleasing scuba mask that also functions to your needs and wants may also be desired.
Let’s take a look at the pros and cons of scuba mask windows.
One Window In the beginning there was one…window. Scuba masks started with a single pane of glass, but the one-windowed versions of today are much more sophisticated. The obvious benefit here is more field of view. Without a piece in the center connecting two separate lenses, divers have less view obstruction. Lower volume is also a usual selling point. With less air inside the mask, it makes clearing and equalizing that area much easier.
Two Windows A two window mask is just that, a mask with two separate windows, or lenses. Typically divers using prescription masks opt for this type because the two window design if more practical (however, a single corrective lens is possible in a one window design). Two window masks tend to be more compact. And durability can also be higher since there is more frame to improved structure.
Multiple Windows Finally, you may be thinking of a mask with side windows. These come with three and four windows. The benefit here is even more field of view (which can really help if a diver feels a bit claustrophobic). However, the where the lenses meet can create a distortion in that field of view or can even create a blind spot. In the end though, whether this calls for concern is up to the diver. The best solution is to ‘test dive’ any mask is possible or at least read the reviews before purchasing.
And learning how to try a mask on is very important.
