The design of the mask can have an affect on comfort of vision and sometimes of wear. There are purge masks, masks that allow speach capabilities, multi window masks, prescription masks. I prefer the purge masks but thats just me
The mask must also fit your face well to make a good seal. And comfort is a huge plus (wore a too small one one time and it hurt my nose and gave me a roaring headache).
I hope to try out one of the color corrected masks soon (the SeaVision)
I wear the Sea vision 2000. It’s incredible! I dive mostly in CA and I have always thought of CA diving as "green and Gray" Not with that mask. I can’t believe how much color there is down there. I haven’t been able to make it out to tropical diving yet but I have a feeling if it makes CA look tropical I am going to be pleasantly surprised!
