The Silhouette SPX Illusion 2942 prescription eyeglasses bring Austrian precision engineering to your everyday wear. These full-rim rectangle frames are built from Silhouette's patented SPX®+ material—a hypoallergenic polymer composite that delivers exceptional lightness without sacrificing durability. The result is a frame you'll barely feel, even after a full day of wear.
SPX®+ Material: Engineered for All-Day Comfort
The SPX®+ material is what sets these frames apart. It's extremely flexible yet resistant to warping, so the frame conforms to your face and stays put without pressure points on your nose or behind your ears. The integrated nose pads and flexible temples are fully adjustable, giving you a personalized fit that's ergonomic and secure. An integrated snap hinge provides a modern look while adding durability—no screws to loosen or lose.
Available in two sizes (54mm and 56mm lens width), the 2942 features a clean rectangle shape that works particularly well for round and oval face shapes, adding structure and definition. The full-rim design provides maximum stability for your prescription lenses, making this frame suitable for a wide range of prescriptions. Temple lengths range from 140mm to 145mm depending on the size you choose.
Prescription-Ready & Built to Last
These frames are prescription-ready and compatible with single vision, progressive, and bifocal lenses. The SPX®+ material is hand-dipped to ensure consistent color throughout the entire frame, and the temple ends feature a matte black finish with shiny end tips for a refined detail. The 2942 comes in multiple color options including black gradient, matte black, petrol, blue, green, and havana tobacco—each offering a different look while maintaining the same lightweight comfort.
Handmade in Austria with the same attention to detail Silhouette has brought to eyewear since 1964, the SPX Illusion 2942 is designed for people who need reliable prescription eyeglasses but don't want to feel weighed down. The frame ships with demo lenses and comes with a protective case and cleaning cloth.

The full-rim design provides excellent stability for prescription lenses of varying strengths. Our licensed opticians can help you select the right lens options for your specific prescription needs.
What is SPX®+ material and why is it used in these frames?
SPX®+ is Silhouette's patented polymer composite material—a lightweight, hypoallergenic alternative to traditional plastic. It's extremely flexible yet highly durable and resistant to warping, ensuring a perfect fit that's fully customizable to your face. The material is also screwless, using integrated snap hinges for maximum durability and a modern look.
What face shapes work best with rectangle frames like the 2942?
Rectangle frames work especially well for round and oval face shapes. The sharp lines and angles of the 2942 provide contrast to round features, creating a slimming and structured effect. The balanced proportions of oval faces also pair beautifully with rectangle frames, adding definition without overpowering natural features.
How much do Silhouette SPX Illusion 2942 frames weigh?
While the exact weight varies by size and color, SPX Illusion frames are exceptionally lightweight—often described as "barely there" by wearers. The SPX®+ material and screwless design minimize weight while maintaining durability. Customers consistently report being able to wear these frames all day without pressure points on the nose or ears.
What sizes are available for the SPX Illusion 2942?
The 2942 is available in two sizes: 54mm lens width with a 14mm bridge and 140mm temples, and 56mm lens width with a 15mm bridge and 145mm temples. Both sizes feature the same rectangle shape and SPX®+ construction. The adjustable nose pads and flexible temples allow for further customization to ensure a comfortable fit.
Are Silhouette SPX Illusion frames durable for daily wear?
Yes, SPX Illusion frames are designed for daily wear and are highly durable. The SPX®+ material is resistant to warping and features integrated snap hinges instead of screws, which eliminates common failure points.

Silhouette SPX Illusion 2942 vs. Similar Models
If you're considering the SPX Illusion 2942, you might also be looking at other models in Silhouette's SPX Illusion collection. Here's how the 2942 compares to three popular alternatives in our catalog.
SPX Illusion 2942 vs. 1617: Rectangle Frame Comparison
Both the 2942 and the SPX Illusion 1617 feature rectangle frames made from the same SPX®+ material, so you'll get identical lightweight comfort and hypoallergenic properties. The 1617 is priced similarly ($216-$218) and offers the same prescription compatibility. The main difference comes down to frame proportions and aesthetic details—the 2942 may have slightly different dimensions or color options. If you're set on a rectangle shape and SPX®+ comfort, compare the specific measurements and available colors to see which better suits your face and style.
SPX Illusion 2942 vs. 2935: Rectangle vs. Round
The SPX Illusion 2935 offers the same SPX®+ material and construction quality as the 2942, but in a round frame shape instead of rectangle. This is a key decision point: rectangle frames like the 2942 work best for round and oval faces, adding structure and definition, while round frames like the 2935 are better suited for rectangle and square faces, softening angular features. Both are priced similarly ($208-$216 for the 2935), so your choice should be based on your face shape and the look you prefer—structured and defined (2942) or softer and more rounded (2935).
SPX Illusion 2942 vs. 1603: Budget-Friendly Alternative
The SPX Illusion 1603 starts at a lower price point ($168) while delivering the same SPX®+ lightweight technology and full-rim prescription compatibility. If you're looking to save some money but still want authentic Silhouette quality and comfort, the 1603 is worth considering. The trade-off is that it has a different frame shape and styling than the 2942, so you'll need to compare the specific design to make sure it matches your aesthetic preferences and face shape needs.
Our recommendation: The SPX Illusion 2942 is an excellent choice if you have a round or oval face and want a rectangle frame that adds structure and definition. The SPX®+ material ensures all-day comfort, and the full-rim design provides excellent stability for prescription lenses. If you prefer a different face shape compatibility or want to explore other styles, the 2935 (round) or 1603 (budget-friendly) are solid alternatives within the same trusted SPX Illusion family.
