ColourVUE Fusion (2 lenses) - dioptric. This range of hydrogel opaque coloured contact lenses from ColourVUE is partially influenced by natural eye colour and light conditions. Fusion daily prescription contact lenses are very breathable, and advanced technology means the colourant stays locked in the bottom layers of the lens. The ColourVUE Fusion contact lenses in the colours Gray/Violet and Blue/Yellow are no longer in production.
