The Silhouette Illusion Lite 2931 eyeglasses bring Austrian engineering and modern style together in a frame that feels nearly weightless. Built from Silhouette's patented SPX®+ material—a flexible, durable polyamide composite developed in 1983—these full-rim frames pair a round SPX front with slim titanium temples for a look that's clean, contemporary, and built to last.
SPX®+ Material: Lightweight Performance
SPX®+ isn't ordinary plastic. This proprietary material offers exceptional elasticity and strength while remaining hypoallergenic and incredibly light. The frames flex to fit your face comfortably and hold their shape over time, resisting warping even with daily wear. Silhouette's screwless snap hinge design means zero maintenance—no loose screws, no adjustments, just reliable performance. The full rim provides maximum lens stability and durability, making these frames ideal for prescription lenses of all types.
Oval Shape for Versatile Fit
The 2931's oval shape is universally flattering and works across face shapes, adding soft definition without overwhelming your features. Available in 49mm and 51mm lens widths, the frame accommodates a range of fits. The round front balances beautifully with the slender titanium temples, which add a touch of refinement and keep the overall weight minimal. You'll find options in rich tones like Havanna Walnut, Trusty Blue, Digital Teal, Restful Olive, and classic Black Shiny—many with gradient or two-tone finishes that give the collection its signature modern edge.
Prescription-Ready Everyday Eyewear
These frames are fully prescription-ready and designed for all-day comfort. The V-bevel glazing ensures a secure lens fit, and the lightweight construction means you can wear them from morning to night without pressure marks or discomfort. Handcrafted in Austria and backed by Silhouette's reputation for precision, the Illusion Lite 2931 is built for people who want quality eyewear that doesn't announce itself—just performs.

Frequently Asked Questions
Are Silhouette Illusion Lite 2931 eyeglasses prescription-ready?
Yes, the Silhouette Illusion Lite 2931 frames are fully prescription-ready and designed to accommodate most prescription lenses. The full-rim design with V-bevel glazing ensures a secure, reliable lens fit. These frames work well with single vision, progressive, and bifocal lenses.
What is SPX®+ material and why is it used in Silhouette frames?
SPX®+ is Silhouette's patented polyamide composite material, developed in Austria in 1983. It offers exceptional lightness, flexibility, elasticity, and strength while remaining hypoallergenic. The material is resistant to warping and provides optimal shape retention, making it ideal for durable, comfortable eyewear that flexes to fit your face perfectly.
How much do Silhouette Illusion Lite 2931 frames weigh?
While the exact weight varies by size and color, Silhouette Illusion Lite frames are designed to be extremely lightweight—often described as 'practically weightless' by wearers. The combination of SPX®+ front and titanium temples keeps the overall weight minimal for all-day comfort without pressure on the nose or ears.
What face shapes work best with the Illusion Lite 2931 oval frames?
The oval/round shape of the Illusion Lite 2931 is highly versatile and flatters most face shapes. Oval frames work particularly well on square or rectangular faces by softening angular features, and they complement oval and heart-shaped faces by maintaining natural balance. The frame is available in 49mm and 51mm lens widths to accommodate different face sizes.
Do Silhouette Illusion Lite frames have screws that can loosen?
No, the Illusion Lite 2931 features Silhouette's screwless snap hinge technology, which is designed to be maintenance-free and exceptionally durable. This innovative hinge design eliminates the need for screws, so there's nothing to loosen or require adjustment over time.
Are Silhouette eyeglasses good for strong prescriptions?
Silhouette frames work best for low-to-moderate prescriptions. For very strong prescriptions that require thicker lenses, the full-rim Illusion Lite style provides better support than rimless designs. The full rim around the lenses offers maximum stability and can better accommodate higher prescription lenses with appropriate lens material choices.

Silhouette Illusion Lite 2931 vs. Similar Models
If you're considering the Illusion Lite 2931, you might also be weighing other frames in Silhouette's SPX and Illusion Lite collections. Here's how the 2931 compares to three popular alternatives in our catalog.
Illusion Lite 2931 vs. Illusion Lite 1607 (Cat-Eye)
Both frames share the same SPX®+ material, screwless snap hinges, and Austrian craftsmanship, but the 1607 brings a cat-eye shape that's more feminine and fashion-forward. If you want to emphasize your cheekbones and prefer a statement frame, the 1607 is a strong choice. However, the 2931's oval shape is more universally flattering across face shapes and works better in professional or minimalist wardrobes. The 2931 is the safer, more versatile pick; the 1607 is for those who want a bit more personality.
Illusion Lite 2931 vs. SPX Illusion Fullrim 1604
The SPX Illusion 1604 is part of the earlier SPX Illusion collection and starts at a lower price ($208.64 vs. $264.62). You get the same lightweight SPX®+ construction and durability, but the 1604 offers fewer modern color finishes and gradient options. If budget is your priority and you're happy with classic tones, the 1604 delivers excellent value. The 2931, however, is the newer design with more contemporary styling and a wider range of two-tone and gradient colors that give it a fresher, more current look.
Illusion Lite 2931 vs. SPX Illusion Fullrim 1605
The SPX Illusion 1605 offers bold color options and a similar full-rim SPX®+ build, with some variants priced under $220. It's a great option if you want vibrant hues and a bit more personality in your frames. That said, the 1605 has a different frame shape that may not suit everyone as universally as the 2931's classic oval. If you prioritize versatility, all-day comfort, and a shape that works across settings, the 2931 is the better choice. If you want to make a statement with color and don't mind a less traditional shape, explore the 1605.
Our take: The Illusion Lite 2931 hits the sweet spot for customers who want modern Silhouette quality, a universally flattering oval shape, and the latest color finishes. It's the most versatile option in this comparison and the best choice for everyday wear across professional and casual settings.
