Flexon 603 N vs Similar Memory Metal Frames
If you're deciding between Flexon's rectangular memory metal frames, understanding the key differences can help you choose the perfect pair for your face shape and budget.
Flexon 603 N vs Flexon 623
Both frames are priced identically at $102.15 and feature the same memory metal technology that makes Flexon frames virtually indestructible. The primary difference lies in frame shape: the 603 N offers a rectangular silhouette optimized for round and oval faces, creating flattering angular contrast, while the 623 features a round frame shape better suited for square or angular face shapes. Both include adjustable silicone nose pads and full-rim construction for lens security.
Flexon 603 N vs Flexon 607
The Flexon 607 is another rectangular option at the same $102.15 price point. Both frames share the titanium-nickel memory metal construction and prescription compatibility with progressive, bifocal, and single-vision lenses. The choice between these models comes down to subtle styling preferences and available color options—both deliver the same legendary Flexon durability.
Flexon 603 N vs Flexon 606
For budget-conscious shoppers, the Flexon 606 offers a lower starting price ($96.62) while maintaining the same memory metal technology. Both frames are part of Flexon's core 600-series collection and provide the lightweight, hypoallergenic benefits of titanium construction. The 603 N's slightly higher price point may reflect additional finish options or design refinements.
Our recommendation: Choose the Flexon 603 N if you have a round or oval face shape and want a structured, professional rectangular look. The clean lines and adjustable nose pads make it ideal for all-day wear, and the memory metal construction ensures it will withstand years of daily use without losing its shape.
