HOW OFTEN WOULD THE DOUBLE ASPHERIC SOLUTION BE NEEDED?
In an analysis of prescriptions received by the laboratory, as many as 46 percent of the cylinder prescription distribution is equal to or more than 0.75 diopters (Fig. 4). That suggests there is a large opportunity in the way one might order aspheric lenses. For spherical prescriptions or low cylinders, lenses would be ordered as "aspheric."

For cylinder prescriptions with values of 0.75 and more, a double aspheric is a better choice for delivering clearer vision with wider fields of view to patients with higher cylinder Rxs.

A PRACTICE-GROWING OPTION
Practice or business growth can be interpreted in a number of ways. For example, improve wearer satisfaction by providing better vision and business should grow. Increase the average lens selling price while watching the cost of eyewear dispensed and profits go right to the bottom line. If both happen, then the overall practice or business grows and as opticians recognize their successes, they use the lenses that support these strategies more consistently.

The single-vision market provides a unique opportunity to grow your business with lenses that deliver increased wearer satisfaction at a reasonable cost. The lens market is large and growing, andmakes up a real part of every office's patient base. In fact, for many offices or chain retail locations, the customer demographics are significant in the number of younger patients seen. Therefore, the aspheric/double aspheric lens is an ideal product whose benefits are worth promoting to patients. By using aspheric and double aspheric designs as your primary dispensed single-vision lenses, you can give your patients a better-looking pair of glasses while delivering improved optics, even for high prescriptions. For the patient's budget, aspheric and double-aspheric lenses are the logical step before free-form, preparing the patient for the option of customized single-vision lenses via direct surfacing as that becomes part of the regular products available from your laboratory. Double aspherics are the practical way to guide your customers to a better quality product and a good option for the full range of astigmatic patients.
