Material aspect
Look at the material composition: high-quality metal spectacle frames often use titanium alloy, pure titanium, etc., with light weight, high strength, corrosion resistance, anti-allergy and other characteristics; Plastic material is cellulose acetate as the best, good texture, not easy to deform, natural color; Natural materials such as tortoiseshell, unique texture, warm texture. If the material composition is not pure or the use of inferior materials, such as ordinary alloys easy to rust, allergies, ordinary plastics easy to deform, fade, the quality is poor.
Check the appearance of the material: a good material surface should be smooth, no bubbles, impurities, cracks and other defects. The metal material should be uniform and bright in color, the plastic material has high transparency and uniform color, and the natural material texture is clear and natural.
Technical details
Welding quality: The welding point of the eyeglass frame should be firm, smooth, no problems such as virtual welding, missing welding, welding scars. Gently shake the connection between the mirror leg and the frame with your hand, if it feels loose, it indicates that the welding quality is poor, which will affect the service life of the frame.
Screws and hinges: screws should be tight and no sliding phenomenon, rotation of the mirror leg, the hinge should be flexible, smooth, moderate opening and closing strength, neither tight nor loose. If the mirror leg is difficult to open and close or there is a catch, there may be a problem with the hinge process.
Surface treatment: high-quality spectacle frame surface treatment fine, uniform, firm coating, not easy to fall off, no fading, peeling phenomenon; The surface of the painting or baking paint should be smooth, smooth, no paint, foaming and other problems.
Design and structure
Overall structural stability: hold the left and right sides of the frame with both hands, gently twist or press, a good frame can maintain its shape, not easy to deform, indicating that its structure is stable and its strength is enough; If it is easily deformed, there may be a problem with the quality.
Size and specification accuracy: the size of the eyeglass frame should meet the standard, such as the width of the frame, the length of the mirror leg, the width of the nose bridge, etc., when wearing, it can fit comfortably with the face, and will not be too tight or too loose. You can view the size parameters marked on the product and compare them with your own facial data, or you can judge them by trying them on.
Ergonomic design: ergonomic eyeglass frame, reasonable design of nose bracket, can evenly distribute pressure, will not cause excessive pressure on the bridge of the nose; The curvature and length of the mirror legs are appropriate, and they can be comfortably hung on the ear without discomfort.
Branding and certification
Brand reputation: Well-known brands usually have more stringent standards and requirements in quality control, production process, etc., and product quality is relatively more guaranteed. You can understand the reputation and credibility of the brand through network evaluation, friend recommendation and other ways.
Quality certification: Check whether the eyeglass frame has relevant quality certification marks, such as ISO certification, CE certification, etc. These certifications are a recognition of product quality, indicating that the product meets certain international or industry standards.
