The Silhouette Titan Dynamics Contour Chassis Rimless 5540 Eyeglasses combine Austrian engineering precision with modern minimalist design. This rimless titanium frame delivers the ultra-lightweight comfort Silhouette has perfected since pioneering the category in 1964, built from high-tech titanium and the brand's proprietary SPX®+ polymer for exceptional durability and all-day wearability.
Modern Rimless Design with Two-Tone Styling
The Titan Dynamics Contour features a clean rimless construction where prescription lenses mount directly to the titanium bridge and temples through precision drill-mount hardware. This creates an unobstructed field of vision and a barely-there aesthetic that puts the focus on your face, not your frames. The collection offers striking two-tone color combinations across six finishes—blue, brown, cream, rose, silver, and black—with temples that blend titanium and SPX®+ for a dynamic, sporty look.
Available in multiple bridge widths (17mm, 19mm, 21mm) and temple lengths (130mm, 135mm, 140mm), the 5540 accommodates a wide range of facial structures and fit preferences. The round lens shape works well for oval, square, and heart-shaped faces, softening angular features while maintaining a contemporary profile.
Engineered Materials: Titanium and SPX®+
Silhouette's high-tech titanium offers an exceptional strength-to-weight ratio—these frames resist bending and breaking while remaining remarkably light. Titanium is also hypoallergenic, making the 5540 ideal for wearers with sensitive skin or metal allergies. The SPX®+ polymer temples add flexibility and resilience; this patented polyamide material is twice as strong as acetate and provides a secure, comfortable fit that adapts to your head shape.
The screwless hinge system integrates titanium and SPX®+ components for smooth, durable operation without the loose screws that plague traditional frames. This is precision eyewear designed to last.
Prescription-Ready Chassis Format
This is a chassis frame, which means it includes the bridge and temples only—no demo lenses. It's designed to be fitted with your prescription lenses by an optician or optical lab. The rimless mounting system accepts single vision, progressive, and bifocal prescriptions, and works best with impact-resistant lens materials like polycarbonate, Trivex, or high-index plastics. The drill-mount design requires precision lens cutting and edging, so professional installation is recommended to ensure proper alignment and optical performance.
The open lens shape and adjustable nose pads make the 5540 compatible with progressive lenses, providing the vertical depth needed for modern corridor designs. For higher prescriptions, pair with high-index lenses (1.67 or 1.74) to minimize edge thickness and maintain the sleek rimless aesthetic.
Handcrafted in Austria, the Silhouette Titan Dynamics Contour 5540 is a versatile, unisex frame that delivers professional style and exceptional comfort for full-time prescription wear.

Frequently Asked Questions
What does 'chassis' mean for this Silhouette frame?
A chassis frame includes only the bridge and temples—no demo lenses are included. The Silhouette Titan Dynamics Contour 5540 chassis is designed to be fitted with your prescription lenses by an optician or optical lab. If you order prescription lenses with your purchase, you'll receive a ready-to-wear pair; if you order the chassis alone, you'll receive the frame components only.
Can I use progressive lenses with rimless Silhouette frames?
Yes, the Titan Dynamics Contour 5540 is fully compatible with progressive lenses. Rimless frames actually work exceptionally well with progressives because the absence of frame lines enhances the seamless vision transition. The round lens shape provides sufficient vertical depth for modern progressive corridor designs, and the adjustable nose pads allow precise fitting height adjustment for optimal clarity.
What is SPX®+ material and why does Silhouette use it?
SPX®+ is Silhouette's patented polyamide polymer, developed in 1983 specifically for eyewear. It offers exceptional lightness, elasticity, and strength—twice as strong as acetate—while remaining hypoallergenic and comfortable. The material allows for precise color finishes and integrates with titanium components in the hinge and bridge systems for screwless, flexible construction that's both durable and lightweight.
Are Silhouette rimless frames durable for daily wear?
Yes, when properly fitted with appropriate lens materials. High-quality rimless frames like the Titan Dynamics Contour are engineered for daily use using titanium and precision drill-mount hardware. The key is pairing them with impact-resistant lens materials like polycarbonate or Trivex, which provide structural integrity at the mounting points. Silhouette's screwless hinge design also eliminates the loose screw issues common in traditional frames.
What prescription strengths work best with rimless frames?
The Titan Dynamics Contour 5540 accommodates most prescriptions, including single vision, progressive, and bifocal lenses. For prescriptions above ±4.00 diopters, high-index lens materials (1.67 or 1.74) are recommended to reduce edge thickness and maintain the sleek rimless aesthetic. The smaller, round lens shape also helps minimize thickness for stronger prescriptions while ensuring the drill-mount points remain structurally sound.
Is titanium eyewear hypoallergenic?
Yes, titanium is hypoallergenic and does not cause skin irritations, unlike nickel-containing metals found in many stainless steel frames. This makes the Silhouette Titan Dynamics Contour 5540 an excellent choice for individuals with sensitive skin or metal allergies. You can wear these frames comfortably for extended periods without irritation at the nose pads or temple contact points.

Silhouette Titan Dynamics Contour 5540 vs. Other Silhouette Rimless Frames
Choosing between Silhouette's rimless titanium frames comes down to style preference, budget, and how much design detail you want. Here's how the Titan Dynamics Contour 5540 compares to three other popular Silhouette rimless chassis options.
Titan Dynamics Contour 5540 vs. TMA Icon II 5541
The TMA Icon II 5541 is Silhouette's legendary minimalist frame—screwless, hingeless, and weighing just ~2 grams. It's been refined over decades and even worn on space missions. If you want the most understated, classic Silhouette experience, the Icon II is unbeatable. However, the Titan Dynamics Contour 5540 offers a more modern, sporty aesthetic with striking two-tone color combinations and visible design details. The Contour's temples blend titanium and SPX®+ for dynamic visual contrast, while the Icon II is pure minimalism. The Contour starts at $304.72 vs. $262.73 for the Icon II, but you're paying for contemporary styling and more color variety. Choose the Icon II for timeless subtlety; choose the Contour for modern, athletic style.
Titan Dynamics Contour 5540 vs. Identity 5535
The Identity 5535 ($296.70) is another rimless titanium chassis with similar construction quality and prescription compatibility. The key difference is aesthetic: the Identity offers different lens shapes and a more neutral design language, while the Titan Dynamics Contour leans into sporty, two-tone styling. Both use titanium and SPX®+ materials, both accept progressive lenses, and both are handcrafted in Austria. If you prefer the Contour's round lens shape and dynamic color blocking, it's worth the slight price premium. If you want a different lens shape or more understated styling, the Identity is an excellent alternative.
Titan Dynamics Contour 5540 vs. Lite Spirit 5566
The Lite Spirit 5566 ($264.62) is Silhouette's most affordable rimless titanium chassis, making it a smart choice for budget-conscious buyers. It maintains the same core construction—titanium, rimless mounting, prescription-ready—but with a lighter, more minimalist design. You sacrifice some of the Titan Dynamics Contour's premium two-tone styling and design details, but you still get authentic Silhouette quality and comfort. If you want maximum subtlety and value, the Lite Spirit is excellent. If you want the sporty, modern aesthetic and richer color options, the Titan Dynamics Contour justifies the $40 difference.
Bottom line: The Titan Dynamics Contour 5540 is the best choice for customers who want a modern, sporty rimless frame with two-tone styling and dynamic design details. It sits between the ultra-minimalist Icon II and the value-focused Lite Spirit, offering contemporary aesthetics and premium materials at a mid-range Silhouette price point.
