The Prescription

The prescription is analyzed by specialized computer software that uses a number of data to find the algorithm that will not only account for the refractive error, but also the unique variations of prescription between both eyes, the chosen frame and the way it will be worn. The resulting prescription provides the best balance of vision, including improved low light vision and color perception.

Manufacturing

These lenses are created on the latest generation computer-driven generators. The generator can read and respond to the new, high-tech prescription written to 1/100th of a diopter. The lenses are created to account for variations of the eyes across the surface of the lens.
