Drill mounts and rimless now make up 25% of all frame sales; it’s a revenue generator that is too important to ignore. But eliminating spoilage and returns is key to making your profits soar. When it comes to drill mounts, lens material and selection matter, and in more ways than you may think. (Shown: Oakley Frame with RESOLUTION Lenses.)

Material Stress is at the Core of Drill Mounting Issues
We’ve all seen lens cracking. It happens when you drill or insert screws or after time, due to tension and stress. Eliminating the stress is key to eliminating cracking and spoilage. Using the right lenses can make all the difference. Polycarbonate has become the lens of choice for drill mounts. Its light weight, high index of refraction and incomparable impact resistance are all desirable features. But antiquated technology used to make polycarbonate lenses has made them less than perfect. The injection compression molding process used to make polycarbonate lenses uses 150 tons of pressure per square inch. That pressure results in material stress. Polarizers reveal the stress as colored striations, and they are indicative of the material stress inherent in polycarbonate lenses. This stress then gets relieved in the form of cracks, chips and flakes. But not all polycarbonate lenses are created equal. Spoilage doesn’t have to be a cost of doing business. Enter a new lens.

Stress cracks are common in other polycarbonate lenses	Birefringence-free RESOLUTION has the material integrity tha prevents lens cracking

RESOLUTION® by Optima, which is made by a patented extrusion compression process that totally eliminates material stress. Spoilage and returns are a thing of the past. Stress cracks as shown (left lens) in the other polycarbonate lens are eliminated with RESOLUTION® (bottom lens). It has the material integrity to eliminate lens cracking. And unlike other lenses, such as Trivex®, RESOLUTION® lenses are finished and do not require any special equipment, nor do you incur any added expenses for surfacing.

Sleek Profiles Made Possible with an Aspheric/Atoric Design
Patients love the minimalist look of drill mounted lenses. Perfecting the look, especially with high minus prescriptions, requires minimizing lens profiles. It’s a task easily accomplished with an aspheric/atoric design. By applying the aspheric design to the steepest portion (curve) of the lens, it allows for the reduction of material mass, making the lens thinner and lighter. By using an atoric design on the backside of the lens, the curvature is flatter and the lens is substantially thinner. RESOLUTION® lenses are the only polycarbonate lenses offering this design. The lenses are up to 14% thinner than other polycarbonates and 10% thinner than 1.60. A 1.2 center thickness and a 1.59 index of refraction make the lenses remarkably light, too.

A Tough AR Coating to Enhance the Minimalist Look
AR coatings improve the wearer’s look by eliminating reflections and making their eyes clearly visible. By increasing light transmission, an AR coating dramatically improves visual acuity, as well. A new AR coating, called CERIUM 58™ by Optima (with its Tantium™ SR base coat) received a Bayer Rating of 7.50. This tough coating stands up to the stringent processing of drill mounts and eliminates any past coating durability issues.

The Optical Perfection of a 1.60, at One-Third the Price
Polycarbonate lenses have been plagued by optical errors. Birefringence not only adds material stress, but the striations are indicative of power variation and resolution loss. Because RESOLUTION® lenses are birefringence-free, your patients get flawless optics. At one half the cost of a 1.60, one half the cost of Trivex and one quarter the cost of a 1.67, using RESOLUTION® lenses becomes a no brainer.
