Soft Contact Lens Identification Guide.

In practice, optometrists occasionally see new patients looking to renew their soft contact lens prescriptions. Frequently these patients are happy with their existing lenses and are seeking to order a year's supply of the same brand. However, the patient often is unsure of the type of lenses they are wearing. This creates a problem, as many practitioners have no way of identifying the lens based on its appearance. Most soft contact lens manufacturers use a system of ink or laser markings to identify the brand and parameters of the lens. Unfortunately, this information has not been made available in the literature. The purpose of this project is to create an identification guide based on the unique markings used by the many companies who produce soft contact lenses. Such a guide would enable practitioners to quickly determine the parameters and type of soft contact lens their patient is wearing.
