PolyTrue™ from GSRx: it's not your father’s polycarbonate

We love polycarbonate for its impact resistance and light weight, but we also know its weaknesses: reduced optical quality compared to other materials and a tendency to crack and chip.  But poly doesn’t have to be that way, which is why we’re proud to offer PolyTrue on our entire epik™ lens series.

The difference between PolyTrue and ordinary poly is not so much in the material itself (it’s still poly), as in the way the lenses are made.  The injection-molding process used for ordinary poly creates internal stresses in the material that can create birefringence (the “oil slick” effect).  PolyTrue is made using a new process (ECM-9™) that virtually eliminates stress distortion and birefringence.This process also increases the integrity of the lens, which drastically reduces the likelihood of chipping and cracking and makes PolyTrue an option for drill-mounts.

But wait – there’s more!  PolyTrue lenses use an advanced aspheric/atoric design that is up to 14% thinner and and 27% lighter than standard polycarbonate.  If you’re dispensing polycarbonate lenses (and we bet you are), give your patients the best with Polytrue.
