The Silhouette SPX Illusion Fullrim 1603 Eyeglasses deliver the Austrian brand's signature ultra-lightweight comfort in a full-rim rectangle frame. Built from Silhouette's patented SPX®+ polymer composite, these prescription-ready frames are engineered for all-day wear without pressure points or slipping.
The SPX material is hypoallergenic, flexible, and remarkably durable—designed without screws for streamlined construction. While the screw-free design simplifies the frame, regular cleaning and proper storage are still recommended to maintain optimal performance. The integrated nose pads and adjustable temples contour to your face for a customized fit. Available in two sizes (53mm and 55mm lens width) and a range of gradient and tri-color finishes including grey, rose, violet, and Havanna Tobacco, the 1603 offers versatile style for both men and women.
The full-rim construction provides lens security and a polished look, while the rectangle shape complements a variety of face shapes. These frames accept single-vision, progressive, and reading prescriptions. Manufactured in Austria, the SPX Illusion 1603 combines European precision with practical, everyday wearability.

Frequently Asked Questions
Are Silhouette SPX Illusion 1603 eyeglasses prescription-ready?
Yes, the Silhouette SPX Illusion 1603 frames are fully prescription-ready and compatible with single-vision, progressive, bifocal, and reading lenses. The full-rim design securely holds lenses of varying thicknesses, making them suitable for a wide range of prescriptions including higher powers when paired with high-index lens materials.
How much do Silhouette SPX Illusion 1603 frames weigh?
The SPX Illusion 1603 frames are exceptionally lightweight due to Silhouette's patented SPX®+ polymer material. While exact weight varies by size, customers consistently report they're "hardly noticeable" during all-day wear. The material is specifically engineered to be lighter than standard plastic acetate while maintaining durability and flexibility.
What is SPX material and is it hypoallergenic?
SPX®+ is Silhouette's patented polymer composite material designed as a lightweight, hypoallergenic alternative to traditional plastic frames. The material is skin-tolerant, flexible, and resistant to warping. SPX frames are also designed without screws, using integrated snap hinges for maximum durability and zero maintenance over time.
Are these frames good for people with sensitive noses or low nose bridges?
Yes, many customers with sensitive noses specifically choose the SPX Illusion 1603 for its lightweight construction and integrated, adjustable nose pads. The flexible temples and nose bridge contour to your face without creating pressure points. The ultra-light SPX material reduces the weight resting on your nose, making these frames comfortable for extended wear even on sensitive or lower bridges.
What sizes are available for the Silhouette SPX Illusion 1603?
The SPX Illusion 1603 is available in two sizes: 53-14-130mm and 55-15-135mm. The first number is the lens width, the second is the bridge width, and the third is the temple length. The 53mm size suits smaller to medium faces, while the 55mm works for medium to larger faces. Both sizes feature the same lightweight SPX construction and adjustable fit.
Where are Silhouette SPX Illusion frames manufactured?
All Silhouette eyewear, including the SPX Illusion 1603, is designed and manufactured entirely in Austria. Silhouette has been handcrafting precision eyewear in Austria since 1964, maintaining strict quality control and using proprietary materials like SPX®+ developed in-house. The brand's Austrian manufacturing ensures consistent quality and craftsmanship.

Silhouette SPX Illusion 1603 vs. Other SPX Illusion Models
The SPX Illusion Fullrim collection offers several models built on the same core technology—Silhouette's patented SPX®+ polymer material. If you're considering the 1603, here's how it compares to its closest siblings.
SPX Illusion 1603 vs. 1604
Both the 1604 and 1603 share identical construction: ultra-lightweight SPX®+ material, screw-free integrated hinges, and hypoallergenic properties. The primary difference is frame shape. The 1603 features a classic rectangle silhouette that flatters round and oval faces, while the 1604 offers a slightly different geometry. Both are priced similarly ($208–$334 range) and available in multiple gradient and tri-color finishes. Choose based on which shape better complements your face structure.
SPX Illusion 1603 vs. 1605
The 1605 is another close variant with the same SPX®+ benefits: feather-light weight, adjustable nose pads, and Austrian craftsmanship. Pricing is comparable at $216–$334. The 1605 may appeal to customers seeking a different lens shape or temple design while maintaining the same material performance and all-day comfort. Both models accept the full range of prescription lenses.
SPX Illusion 1603 vs. 1602
The 1602 offers a lower entry price ($159–$275) while delivering the same SPX®+ material technology. If budget is a priority and you're flexible on frame shape, the 1602 provides identical lightweight comfort, hypoallergenic construction, and prescription compatibility. The 1603's higher price reflects additional color options and potentially more refined finishing details.
Why Choose the 1603?
The SPX Illusion 1603 sits in the mid-range of the collection, offering a versatile rectangle shape, extensive color selection (including unique gradient and tri-color finishes), and two size options (53mm and 55mm). It's the best choice if you want a classic, universally flattering shape with premium color treatments and proven all-day comfort for sensitive noses.
