CP Core Wire Temple Oversized Square Glasses

Hongtu Eyewear develops CP Core Wire Temple Oversized Square Glasses in Taizhou, China, using a mixed-material construction that brings together injection-molded TR90, CP temples, internal wire cores, and metal detailing. With a 55-18-146 mm format, the frame provides a relatively broad front and extended temple length, creating a distinctive option for oversized and fashion-oriented optical collections.

Dimensions

Product Features

1.  Modified Cat-Eye Square Front

The front frame combines a square base with an upward sweep at the outer corners, creating a modified cat-eye outline rather than a conventional rectangular square. This change in contour gives the front more direction and visual lift while preserving enough structure for everyday optical styling.

2.  Broad Front with an Open Lens Area

The 55 mm lens width creates a relatively generous front profile, while the 18 mm bridge keeps the center section visually balanced. The broader lens area is suitable for optical designs that require more room around the eye while maintaining the oversized character of the frame.

3.  TR90 Front + CP Wire-Core Spring Temples

The front frame is made from TR90, while the temples use CP with an internal wire core and spring structure. The two materials serve different parts of the design: the TR90 front provides a lightweight molded base, while the CP temples accommodate the internal wire and flexible temple construction.

4.  Gold-Toned Flat-Needle Temple Detail

The temple ends incorporate a gold-toned metal detail with a flat, geometric profile. Positioned along the side of the frame, the metal element adds a refined contrast to the transparent and molded sections without overwhelming the main silhouette.

5.  Layered Three-Part Temple Appearance

The temple combines a transparent section, a metallic accent, and a finished outer surface to create different layers when viewed from the side. This construction gives the frame more depth than a single-color temple and makes the side profile an important part of the overall design.

How the Temple Construction Works

The CP temple is built around an internal wire core rather than relying on the outer plastic section alone. The wire provides the inner structural element, while the spring mechanism allows additional movement as the temples are opened and worn.

This construction is different from a simple rigid molded plastic temple. It also gives the side of the frame a more adjustable structure while leaving the internal metal core enclosed within the CP material.

Why Use a TR90 Front with CP Temples?

A mixed-material frame allows different sections to be designed around different requirements. TR90 is used for the front, where lightweight molded construction is important, while CP is used for the temples to accommodate the wire core and spring mechanism.

Compared with an all-metal frame, this combination changes the overall material balance of CP Core Wire Temple Oversized Square Glasses. Compared with a basic all-plastic frame, it introduces a dedicated internal structure inside the temples. The result is a hybrid construction rather than simply replacing one material with another.

Side Profile

The front of the frame is intentionally kept relatively clean so that the shape remains easy to recognize. Most of the decorative complexity is concentrated along the temples, where the transparent section, CP body, gold-toned metal detail, and core-wire spring construction work together.

This side-focused detailing is particularly useful for designs that need a recognizable front while still offering something distinctive when viewed from the side. It also gives the model more visual depth without requiring heavy decoration across the lens area.

Oversized Proportions & Optical Fit

The 55-18-146 mm dimensions create a broader front with a longer temple length than many compact optical frames. The larger lens width contributes to the oversized appearance, while the 18 mm bridge provides the center spacing between the lenses.

Frame size should be considered together with facial width, bridge position, pupillary distance, and the intended amount of lens coverage. The oversized designation describes the overall styling and front proportions rather than determining suitability for every face shape.

Color and Surface Direction

The transparent frame provides a neutral base for different color treatments. The layered construction can be developed through changes to the frame tone, temple finish, metallic accent, and other surface details while preserving the modified cat-eye square geometry.

The combination of transparent material and gold-toned detailing creates a different visual direction from a fully opaque black frame. More restrained color combinations can emphasize the shape, while stronger contrasts can make the temple details more visible.

Prescription Lens Considerations

The CP Core Wire Temple Oversized Square Glasses are supplied with demo lenses and is available for prescription lens fitting. The 55 mm lens width and relatively open front should be considered together with the lens material, prescription power, thickness, and optical center during final fitting.

For higher prescriptions, the final lens configuration should be reviewed by the optical professional responsible for fitting to ensure that the selected lenses are compatible with the frame dimensions and prescription requirements.

OEM/ODM Development

The model can serve as a base for customized eyewear development. Changes can be made to frame colors, transparent effects, temple finishes, metallic accents, logo application, packaging, and selected design details according to the final project specification.

For a new design, physical samples or technical drawings can be used as the starting point. This allows the front contour, temple construction, color relationships, and branding details to be established before production.

Why Choose Hongtu Eyewear?

Hongtu Eyewear has more than 15 years of experience in eyeglass frame development and production, with capabilities covering TR90, CP, and PC injection-molded eyewear. The factory also supports customized development based on physical samples and technical drawings.

For this model, the existing CP-related production capability is relevant to the wire-core spring temples, while TR90 injection molding supports the front-frame construction. OEM/ODM services cover product development, colors, logos, packaging, and related customization.

CP Temple Manufacturing Capability

The company's product range includes CP temple and core-wire temple designs, providing a production foundation for models that require an internal wire structure rather than a simple solid plastic temple.

Development Before Mass Production

Samples or drawings can be reviewed during the development stage to establish the required frame shape, color treatment, temple construction, and branding details before formal production.

Q&A

Q: What makes this frame different from a standard square optical frame?

A: The front combines a square base with an upward-swept cat-eye contour. The result has more directional outer corners and a stronger fashion profile than a conventional flat square frame.

Q: Why are CP temples used with the TR90 front?

A: CP provides the outer temple structure needed to house the internal wire core and spring mechanism, while TR90 is used for the lightweight molded front.

Q: Can the wire core be adjusted?

A: The internal wire forms part of the temple construction and contributes to its shaping characteristics. Any fitting or adjustment should be performed carefully by an eyewear professional to avoid affecting the spring mechanism or temple structure.

Q: What is the purpose of the gold-toned temple detail?

A: It provides a defined metallic accent at the temple end and adds another visual layer to the transparent and CP construction.

Q: Is this an oversized frame?

A: Yes. The 55 mm lens width and overall front proportions give the model an oversized direction. Actual fit still depends on facial width and the wearer's preferred coverage.

Q: Can the transparent frame color be customized?

A: Yes. The specification lists the transparent frame color as customizable. Different color treatments and combinations can be discussed during OEM/ODM development.

Q: Can this model be developed from an existing eyewear sample?

A: Yes. Hongtu Eyewear supports development based on physical samples or technical drawings, including adjustments to frame appearance, colors, temple details, branding, and packaging.

Q: Can prescription lenses be fitted?

A: Yes. Demo lenses and prescription lenses are both available. The final lens selection should be evaluated according to the prescription, lens dimensions, and fitting requirements.
