Advantages of having custom corrective lens masks instead of 'stock corrective lens masks' or 'readers' lenses in your dive mask: Stock corrective lenses only correct for the Spherical portion of your prescription in half Diopter increments. If you need bifocal correction, stock corrective lenses only have one position in the lens. The SeaVision® custom prescription lens provides exact correction for the Spherical, Cylindrical, Axis and Bifocal (often written as ADD) of your prescription. Both positive (+) and negative (-) Diopters are available so you can see perfectly. The SeaVision® mask features a unique, Underwater Bifocal correction. It will be ideally positioned on the lens for optimal in-water use. These custom lenses will work like your eyeglasses you use land side.
