The Silhouette SPX Illusion Fullrim 2943 Eyeglasses bring together precision engineering and all-day wearability in a square unisex frame that works for prescription lenses of any strength. Built from Silhouette's patented SPX®+ polymer composite, these frames deliver exceptional lightness without sacrificing durability.
SPX®+ Material: Lightweight, Flexible, Built to Last
SPX®+ is a high-performance polyamide engineered for strength and flexibility. The material's low density keeps frame weight minimal, reducing pressure on your nose and ears during extended wear. That flexibility means the 2943 can bend and stretch during daily wear without snapping or losing its shape. The material has shape memory, so it holds its fit perfectly over years of use. It's also hypoallergenic and contains no plasticizers, making it ideal for sensitive skin or anyone who wears glasses all day.
The full-rim construction provides maximum lens stability and durability. The integrated nose pads and flexible temples are fully adjustable by your optician to ensure an ergonomic, personalized fit. Silhouette designed these frames with integrated snap hinges—no screws—for a cleaner look and zero maintenance. The frames contour to your nose and stay in place all day without slipping.
Prescription-Ready for Any Lens Type
The 2943 accepts single vision, bifocal, and progressive lenses. The square shape and full-rim design provide enough vertical lens height for progressive prescriptions. Available in two sizes—53mm and 55mm lens width—to fit a range of face shapes. The frame comes in multiple color options including matte black (9030), petrol blue (5010), and havana tobacco (9110), with some featuring gradient or tri-color finishes.
The SPX Illusion collection has become a mainstay in premium eyewear, and the 2943's clean lines and versatile square shape make it suitable for work, home, or anywhere in between.

Frequently Asked Questions
Are the Silhouette SPX Illusion 2943 frames compatible with progressive lenses?
Yes, the SPX Illusion Fullrim 2943 is fully compatible with progressive and bifocal lenses. The full-rim square design provides sufficient vertical lens height to accommodate the multiple focal zones required for progressive prescriptions. The frames can be fitted with single vision, bifocal, or progressive lenses according to your prescription needs.
What is SPX material and how is it different from regular plastic frames?
SPX is Silhouette's patented polyamide polymer composite, not standard plastic. It's twice as strong as traditional acetate yet significantly more flexible, with a specific gravity of just 1.04 making it lighter than acetate or even some titanium alloys. SPX is hypoallergenic, contains no plasticizers, and has shape memory so it holds its fit over years of wear without becoming brittle.
Can the nose pads on the SPX Illusion 2943 be adjusted for a better fit?
Yes, the SPX Illusion 2943 features integrated nose pads and flexible temples that are fully adjustable. Your optician can customize the fit to ensure the frames are ergonomic and personalized to your face shape. The SPX material's flexibility allows for precise adjustments that the frames will hold over time.
How much do the Silhouette SPX Illusion 2943 frames weigh?
While the exact weight varies by size, SPX Illusion frames are described as "practically weightless" due to the SPX®+ material's low density. Wearers often describe the sensation as barely feeling the frames on their face, which reduces pressure on the nose bridge and behind the ears—ideal for all-day wear.
What sizes are available for the Silhouette SPX Illusion 2943?
The SPX Illusion Fullrim 2943 is available in two lens widths: 53mm (with 17mm bridge and 140mm temple length) and 55mm (with 18mm bridge and 145mm temple length). The different sizes accommodate various face widths and ensure a proper fit for both men and women.
Are Silhouette SPX Illusion frames good for people with sensitive skin?
Yes, SPX®+ material is hypoallergenic and contains no plasticizers like phthalates, making it an excellent choice for people with sensitive skin or metal allergies. The material won't cause irritation even with prolonged wear, and the lightweight design reduces pressure points that can cause discomfort.

Silhouette SPX Illusion Fullrim 2943 vs. Similar Models
If you're considering the SPX Illusion Fullrim 2943, you might also be weighing other models in Silhouette's SPX Illusion Fullrim collection. All share the same patented SPX®+ material—lightweight, hypoallergenic, and flexible—but differ in frame shape and style.
SPX Illusion 2943 vs. 1605: Square vs. Geometric
The 2943 features a classic square shape that suits most face shapes and offers a professional, versatile look. The 1605, by contrast, has a more geometric, angular design that makes a bolder statement. Both are built from the same SPX®+ polymer and offer identical comfort and durability. Choose the 2943 if you want a universally flattering square frame that works in any setting. Go with the 1605 if you prefer a more contemporary, fashion-forward geometric look and don't mind a slightly higher price in some configurations.
SPX Illusion 2943 vs. 1604: Square vs. Modified Oval
The 1604 offers a modified oval shape—softer and more rounded than the 2943's square geometry. If you have an angular or square face, the 1604's curves can provide a flattering contrast. However, the 2943's square shape tends to be more modern and works well for both round and oval faces. Both frames accept progressive lenses, though the 2943's square design typically provides more vertical lens height for complex prescriptions.
SPX Illusion 2943 vs. 2935: Same Collection, Different Details
The 2935 is from the same 2900-series generation as the 2943, so you'll find similar design language and pricing. The key difference is in the specific frame shape and available color options. Both deliver the same SPX®+ benefits—practically weightless, hypoallergenic, and built to last. If the 2943's exact shape or color options don't match your preference, the 2935 is worth exploring as a close alternative.
Why choose the 2943? The square shape is the most versatile and universally flattering of the group. It works for professional settings, casual wear, and everything in between. The 2943 is available in multiple sizes (53mm and 55mm) and a wide range of colors including matte black, petrol blue, and havana tobacco—many with hand-applied gradient finishes. If you want a reliable, everyday frame that disappears on your face but looks sharp, the 2943 is the safe, smart choice.
