I use hard type multifocal lenses in a normal mask for many years now. For me it's perfect, but some people can't use these lenses because their eyes are too dry.
Hi, I photograph quite a long time now. For many years with compact cameras, now with an Olympus 5 M3 in a Nauticam house and two Inon 330 II strobes. After a lot of macro hoping to improve my wide angle when waters allow. Dives in the Netherlands and a lot of other places.
