The Persol 649 is one of the most iconic sunglasses ever made — but are they worth buying today? In this Persol 649 review, I break down the design, build quality, and style versatility to help you decide if these sunglasses are an essential for your wardrobe in 2026 and beyond.

Design

You might have heard the adage “style equals function” which basically means that in order for an item to be stylish, it first needs to incorporate function as the primary consideration.

Simply put, the Persol 649 was designed in 1957 with one primary goal: to protect the eyes of tram drivers in Italy from dust and debris. It became a style icon later — not by intention, but as a natural consequence of a design rooted in function.

The fact that these sunglasses look so cool and distinctive was almost incidental — but I’ll gladly take that. Honestly, name another item designed for utilitarian purposes that looks this good and went on to become a legendary style icon.

Build Quality

The Persol 649 is made from premium acetate, a material derived from plant cellulose. Acetate is produced in sheets, which are then cut and shaped into the individual parts of the sunglass frame.

One of the most remarkable qualities of acetate is the natural variation in color depth and pattern. Because it’s a natural material, no two pairs are exactly the same — meaning your Persol 649s are truly one of a kind.

Other benefits of acetate include its ability to be molded and adjusted to fit the face and head perfectly, as well as its hypoallergenic qualities which make it a good option for people with sensitive skin.

The acetate components of the Persol 649 are reinforced with durable metal inserts at the hinges, bridge, and temples. The hinges feature a five-barrel metal design, which makes them incredibly strong and long-lasting.

The bridge has a distinctive construction and incorporates Persol’s Victor Bridge, adding both stability and a unique aesthetic.

But the most defining and impressive feature of Persol sunglasses is the Meflecto stem system. This innovative design adds flexibility to the hinges, allowing the sunglasses to adapt to different head sizes and ensuring all-day comfort.

It’s this combination of impressive craftsmanship and thoughtful engineering that sets Persol apart from other brands.

Lenses

The Persol 649 is fitted with crystal glass lenses made by Barberini, a renowned Italian manufacturer known for producing some of the finest optical lenses in the world. Glass lenses are superior to plastic lenses because of their exceptional clarity and durability.

Because glass is significantly harder than plastic, it is far more resistant to scratches and everyday wear. By comparison, plastic lenses—often referred to as CR-39 in the eyewear industry—can pick up fine scratches even with normal daily use. Over time, this difference becomes even more noticeable, with Persol’s glass lenses offering a much longer lifespan than plastic lenses.

The Persol 649 is available with solid and gradient lenses, as well as polarized options. All are excellent choices, and selecting one over another comes down largely to personal style

All things considered, Persol sunglasses are incredibly well made and sure to last many years if taken care of (which basically means being stored in the case when not being worn).

Style Versatility

In one sentence; the Persol 649 are probably the most versatile sunglasses ever made.

I’ve worn these sunglasses to weddings with a black tuxedo. I’ve also worn these to airshows with a t-shirt and shorts. If you truly just need 1 pair of sunglasses, then I highly recommend getting these. They’ll serve you well in practically any situation.

Colours

You have many frame and lens colours to choose from which can be overwhelming especially when you are buying your first pair. To keep things simple here are a few guidelines.

Formal Style

If you wear a lot of formal and business casual attire, then I highly recommend getting the 649 in a black or dark brown frame with dark lenses. These go well with suits and business casual outfits.

On the other hand if you wear mostly casual outfits, then get the 649 in a more bold colour like the Resina E Sale. These bolder colours will help you stand out and totally elevate your casual outfit.

Things to Consider

The thing most people get wrong with the Persol 649 sunglasses is the sizing. Get the correct size and you look vintage cool but get the wrong size and you look like you’re wearing something that doesn’t suit your face.

Here this gentleman is wearing the Persol 649 in a smaller than ideal size (probably 52mm) which just doesn’t look good on his face.

Here’s the same guy wearing the proper size (probably 54mm) and he looks great!

The 649 model comes in 3 sizes, the 52mm (small), 54mm (average) and the rare 56mm (large). The 52mm is great for men with smaller heads. The 56mm is really just for men with massive heads. For everyone else I highly recommend getting the 54mm because it fits most average head sizes the best.

If you have any doubts, then I recommend ordering both the 52mm and the 54mm and trying them on. Keep whichever one suits your face and head size the best.

But keep in mind, when you first try on the 649’s your first impression might be that these are oversized (too big) but trust me, that’s the way Persol sunglasses are designed and made to look. You have to embrace the style.

Price

The Persol 649 typically retails between $363 for non-polarized lenses and $427 for polarized versions. You can also find occasional deals around the holidays but the prices are usually fairly consistent year round.

At this price point, the Persol 649 is absolutely worth the investment. Unlike many iconic sunglass models—such as the Ray-Ban Classic Aviator, which has been endlessly copied by nearly every eyewear brand—the 649 stands alone. There is simply nothing else on the market that exudes the same level of class, vintage style and masculine sophistication.

Considering the quality of the acetate frame, the long term durability and clarity of the crystal glass lenses and the unique and timeless style of the 649, they are a must have for any man who takes his style seriously. You can confidently buy these sunglasses today and wear them for the next 10-15 years knowing they’ll always remain in style.

Final Thoughts

I hope you enjoyed this detailed review of the Persol 649. It’s hard to go wrong with this model — it’s a timeless, high-quality pair of sunglasses that has stood the test of time. Whether you’re dressed in a formal suit or something more casual, the Persol 649 has the ability to elevate your overall look in almost any setting.
