Special Lens Treatments

NXT/TRIVEX MATERIAL

Stacks Image 1482NXT and POLYCARBONATE are resin-polycarbonate and pure polycarbonate materials available in  some of our lens filter options. They afford increased impact resistance and roughly a 20% reduction in thickness over more conventional materials, however colors, densities of tint and prescription powers are limited.  These materials can require more production time and additional costs.    They’re definitely not for everybody!  Inquire and we will be happy to weigh pros cons and availability.

LENS  ROUTING AND STEP BEVELING

Stacks Image 778Stacks Image 780Opticus can fit most glacier frames with prescriptions but some lenses can present challenges to proper side shield attachment as well as proper insertion into sport frames featuring sharp curves and narrow grooves. Opticus addresses these obstacles with two procedures called Routing and Step Beveling. These processes correct the lens profile for a trouble free fit. – The cost is $25 per pair, if needed.

ANTI-FOG COATING

antifogA longer lasting anti-fog substrate can be applied to most of our lenses. This substrate functions like a “magnet” allowing a refresher application to last longer and more efficiently. This “refresher” should be applied once a month according to instructions. Heavy exposure to water can require an additional refresher treatment to rejuvenate the anti-fog function. Is this a perfect answer to fogging? No, it simply helps to mitigate this nuisance to a more acceptable level.  Cost $60 (Includes initial spin cast coating procedure and refresher kit)

DIGITAL WRAP COMPENSATION

Stacks Image 1556The  curvature of sport wrapped frames can drastically effect prescriptions beyond the effect of more traditional frames. A DIGITALLY COMPENSATED lens utilizes computer driven aspheric power modifications to decrease peripheral distortion and increase the area of optimum visual clarity. This process is available in prescriptions totaling over -2.50 to -4.00 in 8 base wrap frames. Cost $75    Prescriptions beyond this point cannot be wrap compensated and thus require a more moderately curved frame.
