Special Lens Treatments

TRIVEX & POLYCARBONATE

TRIVEX and POLYCARB are resin-polycarbonate and pure polycarbonate materials available in limited 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 require more production time and additional costs. They’re definitely not for everybody! We’re happy to weigh pros, cons, availability and costs.

ROUTING:  CHAMFERING AND STEP BEVELING – Cost $25

Opticus can fit most glacier frames with prescriptions but some lenses can present challenges to proper side shield attachment or proper insertion into sport frames featuring sharp curves and narrow grooves. Opticus addresses these obstacles with two ROUTING  techniques called Chamfering and Step Beveling. These processes involving special wheels and bits, correct the lens profile for a trouble free fit.                                                                                               

ANTI-FOG COATING – Cost $60

A longer lasting anti-fog substrate can be applied to most lenses.  Functioning  like a “magnet”, this process allows the anti-fog coats to last longer and more efficiently. A “refresher” is included and should be applied once a month according to instructions. Heavy exposure to water can require more frequent treatment to rejuvenate the anti-fog function. Is this a perfect answer to fogging? No, it simply means lens treatments are necessary less often. Note: Some single vision clear prescriptions such as those in our ski goggle adaptors, are available using a coating that requires no refresher. When applicable and available, we will utilize this product and no refresher will be necessary.                                                

DIGITAL WRAP COMPENSATION – Cost  $100

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 available in prescriptions totaling over -2.50 to -4.00 in 8 base wrap frames. Prescriptions beyond this point cannot be wrap compensated and thus require a more moderately curved frame.
