Persol sunglasses promise the highest quality, attention to detail, dedication to innovative technology, and superb European design. They are one of the last remaining brands that still craft their glasses by hand, and they use only the finest materials to create their frames and lenses. The collection of Persol sunglasses for men and women at FramesDirect.com includes innovative crystal lenses—known as "The Pride of Persol"—in a wide array of colors.
What do pilots, train operators, and mountain climbers have in common? All three were some of the groups that Persol was problem-solving for when they created their first specialty lenses in the 1920s. Persol invented lenses to meet the specific needs of these disparate groups who faced different optical challenges while on the job. Their trademark yellow-brown crystal lenses were used in the famous Protector glasses—adopted by the Swiss military and protected by international patents. These special lenses, crafted from pure silica, offered previously unseen sun protection. By the '60s, American astronauts were wearing Persol, and the innovative, durable shades were accompanying famous explorers and adventurers on their treks, keeping their eyes safe even in the most extreme climates and conditions.
Persol's ultra-light crystal lenses are polarized. Polarized lenses are preferred by drivers as it reduces the glare that reflects off of the surfaces all around us, including the sand, sea, snow, and of course the asphalt of the road. Special filters in the crystal lens block reflected light before it reaches your eye. The filter is created by inserting a thin layer of organic polarizing material between 2 optical crystal lenses. The lenses are made using the most up-to-the-minute techniques to mold and temper the glass. This ensures the lens is as thin as possible, reduced from 2.2mm in thickness to just 1.8mm, resulting in a lighter, more comfortable lens.
Persol offers a range of lens tints for a variety of activities. Blue lenses are good for color perception and brown lenses improve depth perception and contrast. For a general use lens, gray is always a safe bet. It's the darkest tint—so it filters out the maximum amount of light and reduces eye fatigue. Green is also a good general use color, offering superb contrast, even in low-light. Persol lenses are also available in a gradient tint that looks cool, but also serves a purpose: It protects your eyes at the top of the lens (where the sunlight enters) but gradually fades to a lighter tint so it’s easier to see your dashboard, book, or move from outdoors to indoors without removing your glasses.
