What was the challenge?

Prescription neutrality & Lens shape neutrality
To design an eyewear system that features prescription and base-curve neutrality, so that face form angle and tilt are not influenced by the optical lenses.
To design a frame that provides a consistent fit independent of lens power or curves.
To eliminate adjustment surprises when high minus, plus or astigmatic prescription lenses are mounted.
To design a frame that allows for the mounting of a large variety of lens shapes and sizes.

Strength, Flexibility & Lightness
To develop a frameless eyewear system that is strong yet light.
To prevent stress cracking, creep and deformation.
To eliminate screws, soldering or welding from the assembly.
To prevent loosening temples.
To design a frame that has enough flexibility so when the frame is subjected to excessive forces it is not damaged.

Cost
To develop an eyewear system with minimal manufacturing costs.

Environmental impact
To reduce the environmental impacts associated with the lifecycle of the product.

Form & Function
To develop an eyewear system with maximum adjustability.
To fit the largest demographic of users comfortably, with the 1st set of production tooling.
To secure any prescription lens to the frame reliably.

Lens mounting
To develop a low cost solution for retailers to perform the lens drilling process in house.
