Double front structure, the unique Four Nines mechanism consists of a face front and an inner front. Face front that creates a flow to a Gyaku-R-hinge and a temple releases the stress on frame. The inner front holding the lenses constructed independently from the source of stress isolates the lens away from stress while raising the best balance between the frame and lens curvature. It is a construction which improves stability and the overall completeness of the frame.
Gyaku-R hinge placed behind the brow bar creates an ideal frame balance by releasing stress away from the frame at its optimum performance. The remarkable comfort will remain for a prolong period of time. It is a model which appeals to longtime fans, by combining Four Nines’ symbolic construction of double front structure and Gyaku-R hinge at a more simplified form.
The unique curvature of the original square nose pad ensures maximum contact with the nose achieving a pleasant feel of touch. The wide temple end tips are applied with a groove and a matt finishing on the internal surface to enhance grip and comfort. As these are the parts that come into contact, careful attention has been paid to every detail, resulting to an achievement of a comfortable fit.
