DESCRIPTION RATINGS & REVIEWS PRESCRIPTION GUIDE

The Flexon WASHINGTON 600 eyeglasses bring professional style and real-world durability together in a half-rim rectangle frame built for men who need eyewear that keeps up. Featuring Flexon's proprietary memory metal technology in the bridge and temples, these frames can be bent, twisted, or flexed and return to their original shape—a titanium-based alloy originally developed for NASA that's proven itself in millions of frames over three decades.

Memory Metal That Actually Works

The WASHINGTON 600 uses a titanium-nickel alloy (NiTiNOL) engineered to handle the unexpected. Drop them during a project, have a toddler grab them off your face, or accidentally sit on them—the memory metal construction bounces back. This isn't marketing speak; it's the same material NASA used for missile heat shields, and it's why Flexon frames have earned a reputation for lasting years longer than conventional metal eyewear. The frames are lightweight, resistant to corrosion and metal fatigue, and require minimal adjustment over time.

Half-Rim Design and Adjustable Fit

The semi-rimless construction keeps weight down while maintaining the structural support you need for prescription lenses. The upper rim provides lens stability, while the open lower portion reduces visual bulk and gives you an unobstructed field of view—particularly useful for reading or computer work. Adjustable PVC nose pads let you fine-tune the fit to your face, preventing slipping and distributing weight evenly across the bridge. This is especially helpful if you wear glasses all day or have a lower nose bridge.

Available in three finishes—Gunmetal (033), Brown (210), and Dark Slate Blue (412)—and two sizes (54mm and 56mm lens width), the WASHINGTON 600 works well with most face shapes. The rectangle shape adds definition to round or oval faces, while the clean lines suit professional and casual settings equally well. These frames are prescription-ready and compatible with single-vision, progressive, and high-index lenses.

Very satisfied

Have had several Flexon frames in the past, and these continue the streak of comfort and durability. I have a 2-yr old daughter, and the flexible titanium continues to be a winner.

Frequently Asked Questions

What is Flexon memory metal and how durable is it?

Flexon memory metal is a titanium-nickel alloy (NiTiNOL) that allows the frames to be bent, twisted, or flexed and return to their original shape. Originally developed by NASA for missile heat shields, this material is significantly more durable and resistant to fatigue than conventional metals. Customers report Flexon frames lasting years even with daily wear, accidental drops, and handling by children.

Are the Flexon WASHINGTON 600 frames prescription-ready?

Yes, the WASHINGTON 600 frames are fully prescription-ready and compatible with single-vision, progressive, bifocal, and high-index lenses. The half-rim design securely holds prescription lenses using a grooved mounting system, and the adjustable nose pads allow opticians to fine-tune the fit for optimal lens alignment and visual clarity.

What are the benefits of half-rim eyeglasses compared to full-rim frames?

Half-rim (semi-rimless) eyeglasses are lighter than full-rim frames while still providing upper lens support and durability. They offer a more open field of view, particularly useful for reading and computer work, and create a professional, refined look that's less visually dominant than full frames. They're more durable than fully rimless glasses and show more of your face.

What face shapes work best with rectangle eyeglasses?

Rectangle frames like the WASHINGTON 600 work particularly well for round and oval face shapes, as the angular lines add definition and contrast to softer facial curves. They also suit heart-shaped and diamond-shaped faces. The key is choosing a frame width slightly wider than your face's midsection to create visual balance.

Why do these frames have adjustable nose pads?

Adjustable nose pads allow you to customize the fit for maximum comfort and stability. They prevent slipping, distribute the weight of the lenses evenly across your nose, and can be positioned to accommodate different nose bridge heights. This is especially beneficial for people with lower nose bridges, high prescriptions, or those who wear glasses all day.

How do I choose between the 54mm and 56mm size?

The size refers to the lens width in millimeters. The 54mm size (54-18-140) suits small to medium faces, while the 56mm size (56-18-145) works better for medium to larger faces. To determine your size, check the numbers printed inside your current glasses' temple arm—the first number is the lens width. Choose the size closest to what you currently wear comfortably.

Flexon WASHINGTON 600 vs. Similar Memory Metal Frames

If you're considering the Flexon WASHINGTON 600, you're likely drawn to the combination of professional styling and Flexon's proven memory metal technology. Here's how it compares to other popular Flexon frames in our collection.

WASHINGTON 600 vs. MELVILLE 600

Both frames belong to Flexon's 600 series and share the same memory metal construction and price range. The WASHINGTON 600 features a half-rim rectangle design that's ideal for professional settings and suits round or oval faces particularly well. The MELVILLE 600 offers an alternative shape within the same collection—if you like the 600 series technology but want to explore different styling, the MELVILLE is worth comparing side-by-side. Both are prescription-ready and offer the same durability and lightweight comfort.

WASHINGTON 600 vs. AUTOFLEX FRANK

The AUTOFLEX FRANK comes in at $108.31, making it a more budget-friendly option while still delivering Flexon's signature memory metal performance. The AUTOFLEX line is known for enhanced flexibility, which may appeal if you're particularly hard on your glasses or have active kids. The WASHINGTON 600's half-rim rectangle design tends to look more refined and professional, while the FRANK may offer a different frame shape. If price is a deciding factor and you're flexible on style, the FRANK is worth considering.

WASHINGTON 600 vs. E1122

The Flexon E1122 sits at the premium end ($121.60–$140.31) and represents a step up in the collection. It likely offers more advanced styling, additional color options, or enhanced features compared to the WASHINGTON 600. If you're willing to invest a bit more for a premium Flexon frame, the E1122 delivers the same memory metal durability with potentially more sophisticated design elements. The WASHINGTON 600 remains the better value for customers who want proven performance without paying for premium styling.

Our recommendation: The WASHINGTON 600 hits the sweet spot for most customers—it offers Flexon's proven memory metal technology, professional half-rim styling, and a competitive price at $116.31. Choose the MELVILLE 600 if you want to explore different shapes in the same series, the AUTOFLEX FRANK if budget is your priority, or the E1122 if you're looking for premium features and are willing to invest more.
