There is becoming less difference between scuba and spearing/freediving masks than there were. Many scuba masks have followed the trend created by spearing/freediving.
The 2 main elements in a spearing/freediving mask are low volume (air contained inside them) and wide angle of vision.
The small volume is to help reduce the effect of mask squeeze created by increased pressure as you dive down. Breath holding divers have less options than scuba. In scuba the pressure of air increases with depth (as provided by the scuba) and "snorting" air into the mask through your nose equalises pressure in the mask.
Wide vision is useful to all divers both scuba and free but is at a premium when spearing.
Most modern masks are now low volume wide angle. This is usually achieved by placing 2 separate lenses close to the eyes. Any reasonably low volume wide vision mask is good and as or more important is a good fit. A good fit is a personal thing and try before you buy is a must with masks.
