Available in prescription and plano form the lenses are produced from a mid-index material, so are just a little thinner than some other options. The index is n-1.55 in a V40 resin. It adds that the lenses react very quickly Ð from 88 per cent LTF (light transmission factor) to 20 per cent LTF, keeping their true colour and consistent shading.
Norville says the trend for fashion shades of lens tints looks set to continue, and Sun Fun lenses offer a great opportunity to expand sales in this sector.
Norville has also launched a Shootout repair multi-tool kit to provide a quick solution to most frame problems. The patented lever mechanism transforms a gentle squeeze into controlled pressure, thereby reducing damage to the barrel. With a full set of attachments, the Shootout Riveter (pictured below) punches out hinge and eyewire screws, replaces a hinge screw with a QuickFix rivet and flares the screw end to halt loose and lost screws.
The company says this compact tool will easily handle 80 per cent of everyday frame repairs.
