The Geko Optik system from Salice allows wearers of prescription lenses to wear goggles without the need for large OTG goggle styles or having to resort to expensive prescription goggle lenses. The spring loaded arms on the Geko system allow it to be fitted into any goggle! The Geko also gives the wearer the flexibility to change their goggles without having to buy a new set of lenses each time. Simply take the Geko to your optician with your prescription and the supplied lens template, to have your lenses fitted. The kit also features the fog buster spray, making sure your Geko stays fog free
