The Flexon AUTOFLEX 47 eyeglasses bring the brand's proven memory metal technology to a classic rectangular frame that works for everyday wear. Built with a full-rim metal construction, these frames feature Flexon's signature nickel-titanium alloy in the bridge and temples—the same material that made the brand a go-to for anyone tired of bent or broken glasses.
Memory Metal That Actually Works
Flexon frames use nitinol, a nickel-titanium compound engineered to flex, bend, and twist without permanent deformation. The AUTOFLEX 47 takes advantage of this superelastic behavior throughout the frame structure. If you sit on them, drop them, or toss them in a bag, they spring back to shape. It's not marketing—it's materials science that's been field-tested since Marchon launched the technology in 1988.
The rectangular shape suits most face types without looking oversized, and the full-rim design holds prescription lenses securely, including progressives and higher prescriptions. Adjustable silicone nose pads let you dial in the fit, and because the frame is lightweight titanium-based metal, you won't get the pressure headaches that come with heavier frames.
Prescription-Ready and Built to Last
These frames are fully compatible with prescription lenses—single vision, bifocals, or progressives. The full-rim construction provides the structural support needed for thicker lenses if your prescription runs high, and the frame depth accommodates most lens types without issue. Available in multiple sizes (52mm, 54mm, 56mm, and 58mm lens widths) and three finishes: Satin Black, Gunmetal, and Coffee.
Flexon's memory metal frames require minimal adjustment over time. The nose pads and temple tips can be fine-tuned for comfort, but the bridge and temples resist the warping that plagues standard metal frames. If you've replaced glasses because the frames bent out of shape, the AUTOFLEX 47 addresses that directly.

The design of the Flexon AUTOFLEX 47 eyeglasses is exceptional. I particularly like the memory alloy material, which is really flexible and fits me well. I also appreciate the quality of the product. Designer Optics is a great place to buy glasses frames. I would definitely consider buying from them again in the future.
Glass are excellent and took my old lenses and installed them and are good to go.!!

Frequently Asked Questions
Are Flexon AUTOFLEX 47 frames compatible with prescription lenses?
Yes, the AUTOFLEX 47 is fully prescription-ready and compatible with single-vision, bifocal, and progressive lenses. The full-rim metal construction provides excellent support for all prescription types, including higher prescriptions that require thicker lenses. You can add your prescription during checkout, and our certified optical lab will custom-fit the lenses to your exact specifications.
What is Flexon memory metal and how durable is it?
Flexon memory metal is a nickel-titanium alloy (nitinol) that returns to its original shape after being bent, twisted, or flexed. The frames feature this memory metal in the bridge and temples, making them highly resistant to permanent deformation. This technology has been proven since 1988 and is ideal for active wearers or anyone who frequently stresses their frames.
How do I adjust the nose pads on Flexon AUTOFLEX 47 frames?
The AUTOFLEX 47 features adjustable silicone nose pads that can be fine-tuned for a custom fit. You can gently bend the nose pad arms inward to raise the frames higher on your face, or outward to lower them. The nose pad portion is typically held by screws and is not made from the memory metal, making it easier to adjust than the bridge or temples.
What sizes are available for the Flexon AUTOFLEX 47?
The AUTOFLEX 47 is available in four lens widths: 52mm, 54mm, 56mm, and 58mm, with a 19mm bridge width and temple lengths ranging from 140mm to 150mm depending on the size. This range accommodates most face sizes from medium to large. The rectangular shape is designed to suit various face shapes while maintaining a classic, professional appearance.
Are Flexon frames lightweight compared to regular metal frames?
Yes, Flexon frames are significantly lighter than conventional metal frames because they're built from titanium-based alloys rather than heavier metals like stainless steel. The lightweight construction reduces pressure on your nose and ears, eliminating the headaches that can come from wearing heavy frames all day. This makes them particularly comfortable for extended wear.
Can Flexon AUTOFLEX 47 frames be repaired if they break?
While Flexon frames are highly durable and resistant to breaking due to their memory metal construction, they cannot be soldered if they do break because of the nickel-titanium alloy composition. However, the frames are designed to withstand significant stress and bending without permanent damage. Many Flexon frames come with a manufacturer's warranty—check with your retailer for specific coverage details.

Flexon AUTOFLEX 47 vs. Similar Memory Metal Frames
The AUTOFLEX 47 sits at the accessible end of Flexon's lineup, offering the brand's signature memory metal technology at a price point that undercuts optical retail significantly. If you're comparing options within the Flexon family, here's how it stacks up.
AUTOFLEX 47 vs. Flexon 601
The Flexon 601 ($51.50-$141.70) is the closest comparison—both use the same memory metal construction and full-rim rectangular design. The 601 may offer different size options and temple styling, but the core technology and durability are identical. If the AUTOFLEX 47 fits your face and aesthetic, there's no functional reason to choose the 601 over it. The decision comes down to which specific size and color options work for you.
AUTOFLEX 47 vs. Flexon 603
The Flexon 603 ($102.15) steps up in price but delivers the same memory metal benefits. You're paying for updated styling and potentially different fit characteristics, not a fundamental upgrade in materials or durability. If you prefer the 603's look and the price difference doesn't matter, it's a solid choice. But if you're prioritizing value and the AUTOFLEX 47's design works for you, the extra cost doesn't buy you more flexibility or strength.
AUTOFLEX 47 vs. Flexon EINSTEIN 600
The Flexon EINSTEIN 600 ($109.54-$116.31) represents Flexon's premium 600 series with refined design details and potentially enhanced comfort features. The EINSTEIN 600 is worth the premium if you want the latest styling and are willing to pay for it. However, the AUTOFLEX 47 uses the same core memory metal technology, so you're not sacrificing durability or flexibility by choosing the more affordable option.
Why Choose the AUTOFLEX 47?
The AUTOFLEX 47 delivers Flexon's proven memory metal technology at the most accessible price in the lineup. If you need durable, lightweight frames that can handle daily abuse without bending permanently, and you don't need the latest design flourishes, the AUTOFLEX 47 is the smart buy. It's the same nitinol alloy that made Flexon's reputation, just in a straightforward rectangular frame that works.
