Special Lens Treatments
NXT and TRIVEX are relatively new resin-polycarbonate hybrid materials available in some of our lens filter options. They afford increased impact resistance and roughly a 15% reduction in thickness over more conventional materials. 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
Opticus 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.
A 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
The 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 required 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.
