For those with prescription eyewear, ESS has the solution. After the lenses have been corrected by an optometrist, the wire-framed Vice™ Rx Lens Insert snaps into either the ICE™ eyeshield nosepiece or the Advancer V-12™ goggle for a low-profile, lightweight prescription integration. This allows one prescription carrier to work in two products.  The Vice™ Rx Lens Insert accommodates a range of corrections to +/- 6. The Vice™ Rx Insert includes both an Advancer™ goggle adapter and an ICE™ eyeshield nosepiece.  All ESS products are backed by a 1-year warranty against defects in manufacturing and workmanship.
