The Silhouette SPX Illusion 1617 Eyeglasses bring Austrian engineering precision to your everyday eyewear. These full-rim prescription frames feature Silhouette's patented SPX®+ polymer composite—a lightweight, hypoallergenic material that's been a cornerstone of the brand's innovation since 1983. Available in 20 color options including translucent greens, violets, blues, and browns, the 1617 offers a soft rectangular shape with subtle cat-eye influences that complement most face shapes.
What sets these frames apart is the material itself. SPX®+ delivers exceptional flexibility and durability while remaining resistant to warping, ensuring your frames maintain their fit over time. The integrated nosepad system and flexible temples are fully adjustable by your optician for a personalized, pressure-free fit. Silhouette designed these frames without traditional screws, using an integrated snap hinge that's both sleek and built to last.
The 1617 is prescription-ready and works beautifully with single-vision, progressive, and high-index lenses. The full-rim construction provides excellent lens support, making these frames suitable for a wide range of prescriptions. Measurements include a 52mm or 49mm lens width, 15mm bridge, and 140mm temples—offering two size options to fit different face widths. The translucent frame fronts pair with slim metal temples for a modern, refined look that transitions easily from office to evening.
Handcrafted in Austria and part of the SPX Illusion collection introduced in 2015, these frames represent decades of Silhouette's expertise in creating eyewear that you'll barely feel but won't want to take off. The hypoallergenic SPX®+ material makes them ideal for all-day wear, especially for those with sensitive skin. Each pair ships with a protective case and cleaning cloth.

Yes, the SPX Illusion 1617 frames are fully prescription-ready and compatible with single-vision, progressive, bifocal, and high-index lenses. The full-rim design provides excellent lens support for a wide range of prescriptions, and your optician can easily adjust the integrated nosepads and flexible temples for a customized fit with your prescription lenses.
What is SPX®+ material and why is it used in these frames?
SPX®+ is Silhouette's patented polymer composite material developed in 1983. It offers exceptional lightness, flexibility, and durability while being hypoallergenic and resistant to warping. This material ensures the frames remain comfortable for all-day wear, maintain their shape over time, and are suitable for people with sensitive skin.
What sizes are available for the Silhouette 1617 frames?
The SPX Illusion 1617 is available in two sizes: 52-15-140 and 49-15-140. The first number (52mm or 49mm) is the lens width, 15mm is the bridge width, and 140mm is the temple length. The 52mm size fits medium to larger faces, while the 49mm works well for smaller face widths.
How much do the Silhouette SPX Illusion 1617 frames weigh?
While the exact weight isn't specified for this model, Silhouette SPX Illusion frames are engineered to be exceptionally lightweight—typically just a few grams. The SPX®+ material is designed to provide a barely-there feel with minimal pressure points, making these frames comfortable for extended all-day wear.
Can these frames be adjusted for a better fit?
Yes, the SPX Illusion 1617 features integrated nosepads and flexible temples that are fully adjustable by a professional optician. The SPX®+ material is extremely flexible yet durable, allowing for customization to fit your face shape perfectly while maintaining its form over time.
Are Silhouette SPX Illusion frames suitable for people with allergies?
Yes, the SPX®+ material used in the 1617 frames is hypoallergenic, making them an excellent choice for people with sensitive skin or metal allergies.

Comparing Silhouette SPX Illusion Models: Finding Your Perfect Fit
The Silhouette SPX Illusion 1617 sits within a family of exceptional full-rim frames, all sharing the same patented SPX®+ material and Austrian craftsmanship. If you're considering the 1617, here's how it compares to other models in the collection.
SPX Illusion 1617 vs. 1605 vs. 1604
All three models—the 1617, 1605, and 1604—are built with the same SPX®+ polymer composite, offering identical benefits in terms of lightweight comfort, hypoallergenic properties, and durability. The primary difference lies in frame shape. The 1617 features a soft rectangular silhouette with subtle cat-eye influences, making it versatile for most face shapes. The 1605 and 1604 offer alternative geometries within the same price range ($208–$335 depending on lens options).
Choose the 1617 if you prefer a balanced rectangular shape that works well for both professional and casual settings. The integrated snap hinge and screwless design are consistent across all three models, as is the adjustable nosepad system. Color availability varies by model, with the 1617 offering 20 different options including translucent greens, violets, and browns.
SPX Illusion 1617 vs. Illusion 4453
The Silhouette Illusion 4453 represents a different approach within the Illusion family, priced slightly higher at $232.55. While both share Silhouette's commitment to lightweight, comfortable eyewear, the construction and aesthetic details differ. The 1617's SPX®+ material provides maximum flexibility and hypoallergenic comfort, making it ideal for all-day wear and sensitive skin.
The 1617 offers better value for customers prioritizing the proven SPX®+ material technology at a lower price point. Both are prescription-ready and manufactured in Austria to the same exacting standards, but the 1617's full-rim SPX construction gives you the signature barely-there feel that the collection is known for.
Our recommendation: If you're drawn to the soft rectangular shape and want the full benefits of Silhouette's SPX®+ innovation, the 1617 delivers exceptional value. The 20 color options and two size choices (49mm and 52mm) make it easy to find your perfect match.
