The Silhouette SPX Illusion 2961 eyeglasses bring Austrian precision engineering to a modern square frame. Built from Silhouette's proprietary SPX®+ polymer composite, these full-rim frames deliver the brand's signature featherlight feel—you'll barely notice you're wearing them. The translucent finish in colors like blue, grey, black, brown, and petrol gives each frame depth and visual interest, while the square lens shape offers a contemporary look that works for any face shape.
SPX®+ Material: Engineered for All-Day Comfort
SPX®+ isn't standard plastic. This advanced polyamide material has a specific gravity of approximately 1.04, making it one of the lightest frame materials available. It's also hypoallergenic—free from plasticizers like phthalates that can irritate sensitive skin. The material is twice as strong as acetate, highly flexible, and resistant to warping, so your frames maintain their fit even after years of daily wear. The integrated snap hinge adds durability without bulk, and the adjustable temples and integrated nose pads let you dial in a personalized fit.
Who These Frames Are For
If you wear glasses all day—whether at a desk, in meetings, or on the move—the SPX Illusion 2961 is built for you. The lightweight construction reduces pressure on your nose bridge and behind your ears, making these frames ideal for anyone prone to headaches or discomfort from heavier eyewear. The unisex square shape suits a wide range of face shapes, and the translucent color options add a subtle modern edge without being loud. Available in 53mm and 55mm lens widths with an 18mm bridge, these frames are prescription-ready and compatible with single-vision, progressive, and specialty lenses.
Handcrafted in Austria, each pair of SPX Illusion frames is hand-dipped to ensure consistent color throughout. The matte black temple tips with shiny end details are a signature touch. These frames come with a protective case and cleaning cloth.

Frequently Asked Questions
What is SPX material and why is it better than regular plastic?
SPX (or SPX®+) is Silhouette's patented polyamide polymer composite that's significantly lighter than standard acetate plastic, with a specific gravity of about 1.04. It's twice as strong as acetate, hypoallergenic (contains no plasticizers that can irritate skin), and highly flexible yet resistant to warping. This makes SPX frames exceptionally comfortable for all-day wear and ideal for people with sensitive skin or metal allergies.
Are the Silhouette SPX Illusion 2961 frames prescription-ready?
Yes, the SPX Illusion 2961 frames are fully prescription-ready and compatible with single-vision, progressive, and specialty prescription lenses. The full-rim design provides excellent lens retention and works well with a wide range of prescription strengths. You can add your prescription during checkout and choose from various lens options including anti-reflective coatings, transitions, and high-index materials.
How much do the SPX Illusion 2961 eyeglasses weigh?
While exact weight varies by size, SPX Illusion frames are among the lightest eyeglasses available. The SPX®+ material has a specific gravity of approximately 1.04, significantly lower than acetate or even some titanium alloys. Customers consistently describe the wearing experience as 'weightless' or 'barely there,' with minimal pressure on the nose bridge and ears even after hours of wear.
What sizes are available for the Silhouette 2961 model?
The Silhouette SPX Illusion 2961 is available in two lens widths: 53mm and 55mm. Both sizes feature an 18mm bridge width. The 53mm size has a 140mm temple length, while the 55mm typically has a 145mm temple length. The adjustable temples and integrated nose pads allow for fine-tuning the fit to your face shape.
Are SPX Illusion frames good for people with sensitive skin or allergies?
Yes, SPX®+ material is specifically designed to be hypoallergenic. Unlike many plastics, it contains no plasticizers (like phthalates) that can leach out and cause skin irritation over time. The material is also resistant to sweat, cosmetics, and skin oils, making it an excellent choice for people with sensitive skin, metal allergies, or those who experience irritation from traditional frame materials.
How durable are Silhouette SPX Illusion frames?
SPX Illusion frames are highly durable—the SPX®+ material is twice as strong as acetate and extremely flexible, designed to flex under pressure rather than break. The integrated snap hinge adds to the durability while maintaining a sleek look. The material is resistant to warping and maintains its shape over years of daily wear. While no frame is indestructible, SPX frames are engineered for long-term reliability and are a popular choice for everyday prescription eyewear.

Silhouette SPX Illusion 2961 vs. Similar Models
If you're drawn to the SPX Illusion 2961's lightweight comfort and modern square shape, you might also be considering other models in Silhouette's Illusion family. Here's how the 2961 stacks up against its closest alternatives in our collection.
SPX Illusion 2961 vs. SPX Illusion 1604
Both the 2961 and the SPX Illusion 1604 are built from the same SPX®+ polymer composite, so you get identical lightweight, hypoallergenic performance. The key difference is frame shape: the 2961 offers a square silhouette that's versatile and contemporary, while the 1604 may lean more rectangular or have slightly different proportions. Both are priced similarly ($208-$334 depending on options) and work equally well for prescription lenses. Choose the 2961 if you prefer a balanced square shape; go with the 1604 if you want a slightly different aesthetic within the same material family.
SPX Illusion 2961 vs. SPX Illusion 1605
The SPX Illusion 1605 is priced identically to the 2961 at $216.51 and shares the same SPX®+ construction and full-rim design. Customer reviews for the 1605 highlight fast shipping and excellent value compared to retail optical stores. The choice here comes down to personal style preference—both deliver the same featherlight comfort and durability, but the frame shapes and color options differ. If the 2961's square shape doesn't quite match your face shape or style, the 1605 is worth a look as a same-price alternative.
SPX Illusion 2961 vs. Illusion 4453
The Silhouette Illusion 4453 sits at a slightly higher price point ($232-$234) and represents a different branch of the Illusion family. While it shares Silhouette's commitment to lightweight comfort, it may use a different material blend or construction method (possibly semi-rimless or a hybrid design). If you're considering stepping up from the SPX Illusion line, the 4453 offers a premium alternative. However, if you specifically want the proven SPX®+ full-rim construction and value, the 2961 delivers exceptional performance at a lower price.
Our recommendation: The SPX Illusion 2961 hits the sweet spot for most buyers—it offers Silhouette's signature lightweight SPX®+ material, a versatile square shape, and excellent value at $216.51. If you're looking for the best balance of comfort, durability, and modern style in a prescription-ready frame, the 2961 is hard to beat.
