![]() ![]() What happens when you need to clear your mask? “First take the glasses off your mask (and put them in the softcase) and then clear your mask the usual way,” Groeneveld told Divernet patiently – so best ensure that you don’t have a leaky mask. The glasses can be taken off altogether once no longer needed on the dive, such as when the diver pulls away from a reef, and at that point can be deposited in a soft neoprene case attached to the diver by a karabiner. The glasses come in standard aluminium in blue or grey, stainless-steel or titanium An adhesive silicone surface applied to two soft pads on the reverse of the glasses secures them in the diver’s chosen position through friction, says SeeDeep. The glasses can be moved up and down on the dive- mask during a dive, depending on whether the diver wants to peer down at an instrument or up at a pygmy seahorse. The metal-framed lenses are made of hard-wearing polycarbonate with an anti-scratch coating, and the user can choose from four diopters: +1, +1.5, +2 and +2.5. They will fit over the top of any style of dive- mask, according to inventor Jos Groeneveld, and are held in place with an adjustable rubber strap. SeeDeep glasses are not yet in production but the idea is that long-sighted divers can put them on or take them off under water for close-up vision, just as would happen with reading glasses topside. These can be bifocal, and there are other options such as stick-on magnifying lenses or separate prescription lenses that clip inside a mask, though these can have very mixed results for the user. ![]()
