ADDITIONAL LENS TREATMENTS

THE FOLLOWING COATINGS AND OTHER TREATMENTS MAY BE NECESSARY OR PREFERRED TO EITHER IMPROVE HIGHER PRESCRIPTION LENS FIT IN A PARTICULAR FRAME MODEL OR TO IMPROVE THE OVERALL VIEWING EXPERIENCE.

ANTI-REFLECTION COATINGS

THE APPLICATION OF ANTI REFLECTION COATINGS REDUCES LIGHT REFLECTION FROM THE LENS SURFACE. THIS APPLICATION IS GENERALLY INCLUDED WHEN MIRRORS ARE APPLIED TO REDUCE “BOUNCE BACK” FROM THE MIRROR SURFACE. OPTICUS DOES NOT GENERALLY RECOMMEND ANTI-REFLECTION COATINGS ON OTHER OUTDOOR LENSES AS THE REFLECTIONS ARE MINIMAL IN FRAMES WITH EITHER SIDE-SHIELDS OR PROTECTIVE CURVES AND ANTI-REFLECTIVE COATINGS ARE NOT ESPECIALLY DURABLE IN EXTREME OUTDOOR ENVIRONMENTS. $60

ANTI-FOG COATINGS

THE APPLICATION OF AN ANTI-FOG COATING IS HIGHLY RECOMMENDED FOR LENSES BEING PLACED IN PRESCRIPTION ADAPTORS BEHIND GOGGLES. FOR OTHER SUNGLASS APPLICATIONS, IT MAY BE HELPFUL, BUT IT IS NOT AS OF YET, A PERFECT SOLUTION, ESPECIALLY FOR THOSE WITH EXTREME FOGGING ISSUES. THESE APPLICATIONS CAN STILL REQUIRE AN OCCASIONAL USE OF A REFRESHER (INCLUDED), BUT CONSIDERABLY LESS OFTEN THAN AFTER MARKET APPLICATIONS. WHERE A CLEAR SINGLE VISION PRESCRIPTION IS BEING USED, MOST COMMONLY IN A GOGGLE ADAPTOR, A COATING THAT REQUIRES NO REFRESHER IS AVAILABLE WITHIN CERTAIN PRESCRIPTION POWER PARAMETERS. WHERE THIS IS AVAILABLE, IT WILL BE USED AND A REFRESHER WILL NOT BE NECESSARY. $60

AFTER MARKET “DAILY APPLICATION” CLOTHS AND LIQUIDS ARE ALSO AVAILABLE AT CONSIDERABLY LESSER COST AND MAY BE PREFERRED WHERE EXPOSURE TO EXTREME HEAT, COLD AND HIGH HUMIDITY, (THE MOST LIKELY ENVIRONMENTS TO CAUSE FOGGING), ARE ONLY OCCASIONAL.

ROUTING, CHAMFERS AND STEP-BEVELS

THESE ARE LENS EDGE ALTERATIONS EMPLOYED THROUGH SPECIFICALLY DESIGNED MACHINERY, TO CREATE A SPACE FOR BACK LIPS OR SIDE-SHIELDS TO FIT PROPERLY BEHIND PRESCRIPTION LENS EDGES. THESE ALTERATIONS ARE ABSOLUTELY ESSENTIAL FOR CERTAIN FRAMES AND PRESCRIPTIONS TO FIT SUCCESSFULLY. $25

POLYCARBONATE/TRIVEX

POLYCARBONATE AND TRIVEX ARE HIGHER INDEX, THINNER MATERIALS AVAILABLE IN SOME LENS FILTER TYPES AND ONLY WITHIN CERTAIN PRESCRIPTION AND BASE CURVE RANGES. IN MANY CASES WE DO NOT RECOMMEND THEM DUE TO TINTING LIMITATIONS OR SIMPLY BECAUSE THEY WILL NOT BE OF BENEFIT WITH A PARTICULAR PRESCRIPTION, BUT THERE ARE AREAS SUCH AS POLARIZED LENSES, WHERE THEY MIGHT BE AN ADVANTAGE. WE ARE ONLY TOO HAPPY TO DISCUSS THESE MATERIALS WITH REGARD TO YOUR SPECIFIC PRESCRIPTION AND APPLICATION. THERE ARE ADDITIONAL COSTS LISTED ON OUR LENS FILTER DESCRIPTIONS.

WRAP (HEAVY CURVE) COMPENSATION

A WRAP OR CURVE COMPENSATION UTILIZES EITHER PRESCRIPTION ADJUSTMENTS, PRISM INDUCTION, WRAP RELAXATION OR SPECIALLY MANUFACTURED LENSES TO COMPENSATE FOR THE EFFECTS OF CURVES.

 

THEY ARE MOST EFFECTIVE ON PRESCRIPTIONS THAT FALL WITHIN A MODERATE RANGE. FOR HIGHER PRESCRIPTIONS, A FLATTER FRAME MODEL (PRESCRIPTION FRIENDLY) IS DEFINITELY RECOMMENDED. WHERE APPLICABLE, COSTS OF THESE COMPENSATIONS RANGE FROM $50 TO $100 DEPENDING ON THE TYPE NECESSARY.
