Porsche Design is introducing a few models for its 2020 line of sunglasses. One is a new take on the P’8478 model. Designed by Ferdinand Alexander Porsche and released in 1978, this was the brand’s first pair of sunglasses, and purportedly the first sunglasses anywhere to have interchangeable lenses. The updated version is the P’8928, Porsche’s first square aviator sunglasses, also with interchangeable lenses. Each pair comes with an additional set of colored interchangeable lenses, and new lens colors will be introduced every season. They are manufactured in Japan with ultra-light titanium, with suggested retail prices starting at $550.

Meanwhile, the P’8685 Hexagon Gold takes its inspiration from a sports car engine block, with eight hexagonal screws to fasten a front of solid titanium. Each frame is crafted by hand, the temples are made of RXP, and the lenses are polarized. This is a limited edition of 500 pieces, with a retail price of $1,150.

The Fusion models are all about contrasts in “shape, material and surface” – a mix of RXP and metal and of polished and matte surfaces. The P’8366 is a squared aviator for corrective lenses, while the P’8690 is a pair of sunglasses.

The Ultra-Light line, finally, is minimalist, with titanium used “only where absolutely needed.” Each frame weighs five grams, less than anything else in the brand’s catalog.
