Frameless Square PC Stylish Luxurious Metal Sunglasses

Product Features

Frameless Square Design

The square lens shape gives the sunglasses a clear and structured front profile. Without a traditional outer rim around the lenses, the design looks cleaner, lighter, and more open.

This frameless structure keeps the lens outline visible as an important part of the design. It is a suitable option for eyewear collections that need something different from regular full-rim square sunglasses, while still keeping a familiar square shape.

Metal Frame Construction

Metal is used for the main structural parts of the front and temples. The metallic construction works well with the frameless lens layout, adding definition without making the front look heavy.

The design also allows for different metal finishes and color treatments during product development. The product information highlights electroplating treatment, which helps improve the surface appearance and supports resistance to everyday wear.

PC Lens Material

The sunglasses use PC lenses. Polycarbonate is a lightweight lens material often used in modern eyewear, especially for products that need comfort, practicality, and functional lens options.

The product page lists UV400 protection and describes the lenses as lightweight and impact-resistant, making them suitable for daily outdoor sunglasses development.

Polarized Sunglasses Positioning

This model is positioned within the metal polarized sunglasses range. It can be used for collections focused on polycarbonate polarized sunglasses and functional metal eyewear.

The exact lens treatment, polarization effect, and optical specifications should be confirmed based on the final selected production configuration.

Lightweight Construction

With a listed weight of approximately 30 g, the model offers a lightweight product profile. The combination of metal structure and PC lenses helps keep the sunglasses practical for daily wear.

The frameless front also reduces visual heaviness, giving the design a more open and streamlined appearance.

Adjustable Nose Pad Design

The product information includes adjustable silicone nose pads. This design is intended to help distribute pressure around the bridge area and improve wearing adaptability.

Adjustable nose pads also make the sunglasses easier to fit different facial profiles, which is useful for unisex eyewear collections.

Design and Functional Value

This product brings together several common but effective eyewear elements: square lenses, frameless construction, metal structure, and PC lenses.

The 61 mm lens width gives the front a strong square proportion. The 12 mm bridge keeps the center section compact, while the 145 mm temples continue the clean styling toward the sides of the frame.

Instead of using heavy decoration, the design relies on the exposed lens shape and metal details to create its visual character. This gives the sunglasses a clean, modern, and slightly luxury-inspired appearance.

This makes the model suitable for:

• Frameless square sunglasses
• Metal square sunglasses
• Polycarbonate sunglasses
• Polarized sunglasses collections
• Minimalist metal eyewear
• Contemporary fashion sunglasses
• Luxury-inspired eyewear ranges
• Everyday outdoor sunglasses
• Unisex sunglasses collections
