I'm using drop-in prescription lenses with my Cressi Focus, which has worked perfectly and fits my face super well. It's quite low volume too. Recently I've been feeling a touch claustrophobic in this mask though, and hoping to upgrade to something with clear or white silicone. I'm struggling to find an equally low/lower volume mask with soft silicone that I can easily swap the prescription lenses over from the Cressi Focus. I thought the shape of the Focus lenses should be quite popular, but it seems many higher-end masks now use different shapes. Do you know of any better built masks than Cressi Focus accepting the same drop-in prescription lenses?
