Bobbie Full Rim 55O400 Unisex Screwless Titanium Round Frames

Engineering the "138mm Balanced Fit"

The 55O400 is defined by its rigorous geometric symmetry. Featuring a precision-scaled 138mm frame width, these glasses provide a "Standard-Refined" fit—ideal for those who find standard 140mm frames slightly too loose, yet require more presence than a petite 130mm frame. Forged from Grade-A Pure Titanium, this full-rim profile provides a sharp, high-definition border for your lenses while remaining 40% lighter than traditional steel.

Why the Bobbie 55O400 Round is a Professional Benchmark:

• Pure Titanium Architecture: Benefit from the highest strength-to-weight ratio in the optical industry. Titanium is virtually indestructible and naturally non-corrosive, ensuring your frames maintain their "factory-new" alignment despite daily exposure to skin oils or high humidity.

• The 138mm "Proportional Balance": Meticulously engineered for a secure, non-slip grip. The 138mm width ensures the temples provide a gentle, firm hold that keeps your optics perfectly centered, eliminating mid-day adjustments during high-focus tasks.

• Hypoallergenic Skin Security: Titanium is the gold standard for biocompatibility. These frames offer a medical-grade, irritation-free solution—preventing the "red marks" and skin reactions often caused by lower-quality nickel-based alloys.

• Iconic Round Geometry: The perfectly circular rim provides a timeless, intellectual aesthetic that softens angular facial features. It is a versatile choice that transitions effortlessly from the studio to the executive suite.

• CE Certified Engineering: Your vision is an investment. The CE Certification is our global promise that these frames meet the most stringent international standards for material purity, structural safety, and industrial craftsmanship.
