With all these options, we still see some ECPs stuck in the past with not only lens designs but also materials. As an industry, we still see too many CR39 jobs. While CR39 does offer superior clarity, it falls short in many other areas such as UV protection, lower impact resistance, and higher thickness. Lens materials guide for ECPs

It is time to move your patients into higher index lenses. Polycarbonate and high index options offer your patients benefits that standard plastic just cannot. Thinner, lighter lenses give your patients a wider selection of frame choices. Built-in UV protection and impact resistance make everyday life a bit safer for them.

Some of the fear in selling poly is built around Chromatic Aberration. While this is a real thing, it is also fairly rare for your patient to experience an issue with it. Often an ECP will have 1 bad experience with a lens or a material and lose confidence. They will stop selling what is good for the patient out of fear of having another bad experience. This robs their future patients of products that they could benefit from.

The benefits of High Index Materials far outweigh the drawbacks.
