Persol Sunglasses: A Look into Their Technology
Derived from the Italian phrase “per il sole”, which means “for the sun”, the meaning of the name Persol reflects its purpose of protecting eyes from sunlight.
Persol is one of the oldest eyewear companies in the world, with just over 100 years of top-notch craftsmanship and unmistakable design.
The Italian brand was originally founded in Turin in 1917 by an engineer, photographer and aviator named Giuseppe Ratti. Already the owner of the Berry optical shop in the center, Ratti was committed to producing advanced eyewear.
The first pair of Persol sunglasses was designed to protect the eyes of pilots and sports drivers.
Over the following decades, Persol focused on research and technological development, increasingly producing innovative eyewear for mountaineering expeditions, desert rallies and other extreme sports events.
Among other brands in Italy, Persol stands out for its reputation, authenticity and commitment to quality. After 100 years of trading, Persol eyeglasses remains appealing to a wide array of people all around the world.
Persol also has a strong association with cinema, having been featured in numerous iconic movies and worn by celebrities, further cementing its place in popular culture.

In the 1980s, NASA began using Persol sunglasses thanks to their high quality.
Persol lenses
Combining old-world hand-finishing in Lauriano, Italy, with modern optical science, Persol lens technology delivers three things eyewear enthusiasts demand: razor-sharp optics, full-spectrum UV protection and all-day comfort.
For those seeking more information, here are some important details: Persol lenses feature advanced coatings for scratch resistance and oleophobic protection and are available in lightweight crystal, polarised and photochromic options.
These details ensure optimal performance and durability.
As a product made in Italy, Persol lenses reflect a tradition of exceptional craftsmanship and quality.
Polarised lenses
Polarised lenses refer to a micro-thin filter sandwiched between lens layers that block light reflected off sand, roads and water, ensuring clear vision even in extreme environments.
In 1985, Persol’s research and development centre started offering polarised lenses which were used by Russian astronauts and Italian mountaineers.
The 1.8mm super-light Persol sunglasses with polarised lenses are developed from extra-fine glass.
New production techniques have been adopted to shape and temper the glass to reduce lens thickness from 2.2mm to 1.8mm, offering more comfortable and aesthetically appealing frames.
The brand offers both polarised crystal and polarised polycarbonate options; each lens also receives Persol’s 100 % UV filter.
Photo polar lenses
Combining polarised and photochromic lenses in a single pair of Persol frames, this option offers all the benefits of polarisation with the ability to adapt to surrounding light.
When they are exposed to bright light on a sunny day, the lens reacts and darkens in order to offer protection from the sun’s radiation and to prevent eye strain.
As light levels decrease, the molecules return to their original state and become transparent once again.
Persol Photo Polar lens can adapt to any light situation, ideal for anyone who frequently shifts between indoor tasks and bright outdoor environments.
Crystal lenses
Using first-class materials, almost every pair of Persol sunglasses contains crystal lenses. Crystal is one of the most precious natural materials used in creating optical devices.
Crystal lenses make Persol sunglasses scratch-resistant and increase their durability. They offer a high level of protection against harmful rays from the sun and they also guarantee incredible visual clarity.
Precision meets comfort
Persol lenses are precision-made for performance—but it’s the comfort that sets them apart.
In the 1930s, Persol developed the patented Meflecto system, the world’s first flexible stem design. A steel core and dual-cylinder system allows the arms to bend and flex without pressure, adapting naturally to your face.
Later, Persol introduced Victor Flex—a flexible 3-incision bridge that enhances grip, improves fit and adds even more comfort.
Each frame is available in multiple sizes, with bridges of varying heights and arms of different lengths for the perfect fit. The proprietary “Telatura” process distributes lens weight evenly, reducing pressure and providing comfort across long periods.
Though Persol uses advanced production methods, many steps are still completed by hand—where precision, tradition, and technology come together. The result? Timeless eyewear with unbeatable quality.
Frame materials and designs
Persol frames are renowned for their exceptional blend of style, comfort and durability, thanks to the use of premium materials like acetate, a high-quality plastic derived from cotton fibres.
Each pair of Persol frames is thoughtfully engineered to provide a perfect fit and lasting quality, making them a standout choice in the world of eyewear.
Every detail, from the polished finish to the carefully designed temples, reflects Persol’s dedication to quality and comfort, ensuring your glasses stay securely in place throughout the day.
Whether you’re searching for men’s or women’s Persol sunglasses, this brand offers a diverse selection of frame shapes and colours, so you can easily find the perfect pair to match your style while optimising your viewing experience.
