The Silhouette 4375 01 6050 is a lightweight premium optical frame from Silhouette, designed around the brand’s signature philosophy of ultra-minimalist construction, rimless precision engineering, and near-weightless everyday comfort. It belongs to Silhouette’s “Crystal Diva / rimless elegance” design family, which focuses on refined professional styling with almost invisible frame presence.

The 4375 model features a rimless drill-mount structure (3-piece compression system) with a soft rectangular lens shape. This creates a clean floating-lens effect where the lenses appear suspended without a full frame, giving a very light, elegant, and modern aesthetic. The design is especially popular in professional environments where subtlety and comfort are preferred over bold fashion frames.

The 6050 color code corresponds to a silver / crystal-grey metallic finish, which is one of Silhouette’s most classic neutral tones. It gives the frame a clean, technical, and sophisticated look that blends easily with both formal and casual wear while maintaining a discreet luxury identity.

Build & Materials

The Silhouette 4375 is typically constructed using a combination of:

• High-grade titanium metal components
• Silhouette’s proprietary lightweight structural system
• Precision drill-mounted rimless lens fittings

This results in:

• Extremely lightweight wear (barely noticeable on the face)
• High corrosion resistance for long-term durability
• Hypoallergenic properties suitable for sensitive skin
• Flexible but stable lens mounting system

Silhouette is especially known for screw-minimal or screw-free design principles in many rimless systems, which improves durability and reduces maintenance needs.

Design & Comfort Features

Key ergonomic and design elements include:

• Rimless rectangular lens layout (soft executive shape)
• Adjustable silicone nose pads for custom fit
• Slim titanium temples for reduced side pressure
• Balanced weight distribution for long wear comfort
• Drill-mounted 3-piece compression system for lens stability

This design is especially suited for people who wear glasses all day, as it reduces pressure points around the nose and ears.

Fit & Sizing

Common specifications for Silhouette 4375 (varies slightly by variant):

• Lens width: ~52–54 mm
• Bridge width: ~17 mm
• Temple length: ~135–140 mm
• Lens height: medium rectangular profile
• Fit category: small to medium

This makes it suitable for narrow to average face widths with a balanced, professional look.

Lens Compatibility

The 4375 is compatible with:

• Single vision lenses
• Reading lenses
• Bifocal lenses
• Progressive lenses
• High-index lightweight lenses
• Blue-light filtering lenses

Because it is rimless, opticians often recommend lightweight lens materials (Trivex or high-index) for durability and clarity.
