Patented Innovation
Staffan Preutz eyewear are granted the rare distinction of a patent; Pat.pend. no PCT/JP97/010186. The production takes place at Polaris Optic AB, a company certified accordingly with BS-EN ISO 9001.
Lenses
Superior optics and light weight were the most important demands on the lenses Preutz wanted to glaze his product with. After a series of tests, Pentax became the ideal choice. The range of lenses in indexes 1.67 and 1.60 are up to 45 percent thinner and lighter than standard resin lenses! The Pentax lenses have a superior optic function thanks to the advanced aspheric surface design, called Retina Forward Design (RFD). The goal of the design is that the image should always be perfect on the retina, even when looking through the peripheral areas of the lenses where traditional lenses give distortions. Another advantage with RFD is that the eyes of the wearers of high-strength lenses are not distorted, i.e. magnified or reduced. Your eyes will appear clearer through the lenses thanks to the Super Multi Coat (SMC) that reduces reflections to a minimum.
The image below shows the thickness difference between Pentax Super Hi-index lenses and standard resin lenses in different powers.

Metal
Staffan Preutz had a stroke of genius when he discovered an extreme material used in the space industry. The unique combination of elasticity, flexibility and the ability to be shaped and to retain its shape was exactly what he had been looking for. The problem was that the material could not be welded or soldered with existing techniques. Preutz solved this problem with an ingenious design! Staffan Preutz eyewear consists of no less than four different materials forming one piece that has all the functions Preutz wanted to achieve. The patent is proof of the news value! The eyewear fulfills the demands of nickel-safe materials according to the German standard DIN 1811.
