The Silhouette TNG 2018 Chassis Rimless 5521 Eyeglasses deliver the barely-there comfort and clean aesthetic that have made Silhouette a leader in rimless eyewear since 1964. Built from high-tech titanium paired with SPX+ material, this Austrian-engineered chassis offers a lightweight, hypoallergenic frame that adapts to your prescription and personal style.
Titanium Construction Meets SPX+ Innovation
The TNG (Titan Next Generation) 5521 combines aerospace-grade titanium with Silhouette's proprietary SPX+ polymer for exceptional strength without weight. Titanium provides corrosion resistance and flexibility, while SPX+ adds impact resilience. The result is a frame that's durable enough for daily wear yet light enough to forget you're wearing glasses. The rimless design eliminates peripheral vision obstruction, and the hingeless temples reduce moving parts that can wear or break over time.
This chassis includes the bridge and temples but ships without demo lenses—it's designed to be fitted with your prescription lenses in the exact shape you choose. That customization is the point: you select from oval, rectangular, or soft-square lens shapes to match your face and style, then add single-vision, progressive, or bifocal lenses as needed. The frame accepts a wide range of prescriptions and works well with Trivex or high-index lenses for rimless durability.
11 Colors, 7 Sizes, One Unobtrusive Fit
Available in black, blue, brown, gold, grey, orange, petrol, red, rose, silver, and violet, the 5521 offers color options that range from professional neutrals to expressive accents. Temple lengths span 135mm to 150mm, and bridge widths run 17mm to 21mm, ensuring a fit for narrow to wider faces. Adjustable nose pads and the flexible temple design let opticians fine-tune the fit to your face.
"These frames/glasses are super lightweight and I don't even know im wearing them!" — EyeSpecs customer review
The oval shape flatters most face types and provides a professional, understated look that works in any setting. Because the lenses mount directly to the titanium frame via precision-drilled attachment points, the 5521 maintains its minimal profile while staying secure. Silhouette's screwless, hingeless temple design means fewer parts to adjust or replace, and the hypoallergenic materials make this frame ideal for sensitive skin or all-day wear.
Prescription-ready and compatible with anti-reflective coatings, photochromic lenses, and polarized clip-ons, the TNG 2018 Chassis 5521 is built for versatility. Whether you need computer glasses, driving glasses, or everyday frames, this chassis adapts to your vision needs without adding bulk or weight to your face.

Frequently Asked Questions
What does 'chassis' mean for Silhouette eyeglasses?
A Silhouette chassis includes the bridge and temples (the structural frame) but does not come with demo lenses. It's designed to be fitted with your prescription lenses in the lens shape and size you choose. If you order prescription lenses with us, you'll receive a complete, ready-to-wear pair of eyeglasses. Without lenses, you receive the frame components only.
Are Silhouette TNG 2018 frames good for prescription lenses?
Yes, the TNG 2018 Chassis 5521 is fully prescription-ready and accepts single-vision, progressive, and bifocal lenses. The titanium and SPX+ construction is strong enough to hold lenses securely at the drilled mounting points. For best durability with rimless frames, opticians often recommend Trivex or high-index lens materials, which resist cracking around the mount points better than standard plastic.
How much do Silhouette TNG 2018 Chassis 5521 eyeglasses weigh?
Silhouette rimless titanium frames are among the lightest eyeglasses available, with many models weighing under 10 grams when fitted with lenses. The frame-only weight is typically 2-3 grams for ultra-light titanium designs. Customers consistently describe the TNG 2018 as so light they 'hardly notice' wearing them, even during all-day use.
What sizes are available for the Silhouette 5521?
The TNG 2018 Chassis 5521 comes in 7 size configurations: 17-135, 17-140, 17-145, 19-140, 19-145, 19-150, and 21-145. The first number is the bridge width in millimeters (17mm, 19mm, or 21mm), and the second is the temple length (135mm to 150mm). This range accommodates narrow to wider faces and allows for a customized fit.
Are Silhouette rimless frames durable?
Yes, when properly fitted and maintained. Silhouette uses high-tech titanium and SPX+ materials that are corrosion-resistant, hypoallergenic, and flexible. The hingeless temple design eliminates moving parts that can wear out. However, rimless frames do require careful handling because lenses attach at drilled points rather than being cradled in a full rim. Choosing durable lens materials like Trivex and storing them in a protective case extends their lifespan significantly.
Can I add clip-on sunglasses to the Silhouette TNG 2018 frames?
Yes, Silhouette offers custom polarized and non-polarized clip-on sunglasses designed to fit their rimless frames, including the TNG 2018 Chassis models. This allows you to convert your prescription eyeglasses into sunglasses without needing a separate pair. The clip-on option is popular among Silhouette wearers who want sun protection without compromising the lightweight, rimless aesthetic.

Silhouette TNG 2018 Chassis 5521 vs. Titan Minimal Art Stellar 5599
Both the TNG 2018 Chassis 5521 and the Titan Minimal Art Stellar 5599 represent Silhouette's expertise in rimless titanium eyewear, but they serve slightly different preferences. The TNG 2018 offers more color variety (11 options vs. fewer in the Titan Minimal Art) and a contemporary design language that appeals to wearers who want a modern, customizable look. It's available in expressive colors like petrol, orange, and violet alongside classic neutrals.
The Titan Minimal Art Stellar 5599, by contrast, is part of Silhouette's most iconic collection—the screwless, hingeless design that's been space-certified and worn on NASA missions. It's the frame that built Silhouette's reputation for ultra-lightweight engineering, weighing as little as 2 grams. If you want the heritage and recognition of owning "the Icon," the Titan Minimal Art is the choice. If you prioritize color options and a slightly more contemporary aesthetic, the TNG 2018 delivers.
Both use high-tech titanium, both are hypoallergenic and corrosion-resistant, and both ship as chassis (bridge and temples only) designed for prescription lens fitting. The TNG 2018 is ideal for wearers who want personalization and modern styling. The Titan Minimal Art Stellar is for those who want the most minimal, classic rimless frame Silhouette makes—the one with the space pedigree and decades of proven performance.
Our recommendation: Choose the TNG 2018 Chassis 5521 if you want more color choices and a modern look at a competitive price. Choose the Titan Minimal Art Stellar 5599 if you want the iconic, space-certified design and the absolute lightest frame Silhouette offers.
