I found exactly what I was looking for in color and size.
As far as I know now, everything seems great, I am having lens put in now. I’ve used this same frame for years, and have had much success with it. I was unable to find frame locally, so had to order.
Flexon 606 Eyeglasses
I bought a pair of Flexon 606 and i wish they would have more choices on bow sizes for my frames they only offered 140 and I needed 145 . How can I get the 145's that I need?
Great Glasses and frames. Well built and fit and finish is great too

Frequently Asked Questions
What is Flexon memory metal and how does it work?
Flexon memory metal is a titanium-nickel alloy developed by Marchon Eyewear that allows the frames to be flexed, bent, or twisted and return to their original shape. This NASA-discovered technology makes the Flexon 606 significantly more durable than conventional metal frames, reducing the need for adjustments and replacements over time.
Are the Flexon 606 eyeglasses prescription-ready?
Yes, the Flexon 606 frames are fully prescription-ready and compatible with single vision, progressive, and bifocal lenses. The semi-rimless design provides ample lens height for progressive corridors, and the adjustable nose pads ensure proper optical alignment for clear, comfortable vision at all distances.
What face shapes work best with the Flexon 606?
The Flexon 606's rectangular shape is ideal for round and oval face shapes, as the angular lines add structure and balance to softer facial features. The semi-rimless design also creates a lighter, more open look that doesn't overpower your face, making these frames versatile for most face types.
How lightweight are Flexon 606 frames?
The Flexon 606 frames are exceptionally lightweight due to their titanium-based construction and semi-rimless design. Customers consistently report that these frames feel barely noticeable during all-day wear, eliminating pressure on the nose and temples that heavier metal frames can cause.
Can the nose pads on the Flexon 606 be adjusted?
Yes, the Flexon 606 features adjustable silicone nose pads that can be fine-tuned for height, tilt, and width to achieve a customized fit. This adjustability is especially beneficial for those with low or high nose bridges, ensuring the lenses sit at the optimal position for clear vision and all-day comfort.
What sizes are available for the Flexon 606?
The Flexon 606 is available in three lens widths—52mm, 54mm, and 56mm—with a consistent 19mm bridge width and 140mm or 145mm temple length depending on the variant. This range of sizes ensures a proper fit for small to large face widths, and the adjustable nose pads provide additional customization.

Flexon 606 vs. Flexon 607 vs. Flexon 603: Which Frame Is Right for You?
Choosing between Flexon's 600-series models comes down to design preference and how much frame presence you want. All three share Flexon's legendary memory metal technology and lightweight titanium construction, so durability and comfort are consistent across the lineup.
Flexon 606 vs. Flexon 607: Nearly Identical Siblings
The Flexon 606 and Flexon 607 are extremely similar—both feature semi-rimless rectangle designs with memory metal temples and adjustable nose pads. The 607 offers a few additional color options like Black Chrome and Camel Blush, while the 606 provides more size flexibility with three lens widths (52mm, 54mm, 56mm) and a slightly lower starting price. If you prioritize size options and value, the 606 is the better choice. If you want a specific color not available in the 606, go with the 607.
Flexon 606 vs. Flexon 603: Semi-Rimless vs. Full-Rim
The Flexon 603 is a full-rim alternative that delivers a bolder, more defined look. While the 606's semi-rimless design keeps weight minimal and creates a professional, understated aesthetic, the 603's full rim offers more lens protection and makes a stronger style statement. If you prefer lightweight, minimalist frames that don't overpower your face, the 606 is ideal. If you want more frame presence and a slightly more casual look, consider the 603.
Why Choose the Flexon 606?
The Flexon 606 strikes the perfect balance: it's lighter than the full-rim 603, offers more size options than the 607, and delivers a timeless semi-rimless rectangle design that works in any professional or casual setting. With memory metal flexibility, adjustable nose pads, and a price starting under $100, the 606 is an exceptional value for anyone seeking durable, comfortable, prescription-ready eyewear.
