Sunglasses have long transcended their single function of shielding from the scorching sun, evolving into sophisticated accessories that blend optical technology, materials engineering, and fashion aesthetics. For export brands, a deep understanding of their core knowledge, material characteristics, and customization logic is key to confidently navigating this vast market.
I. Three Core Concepts of Sunglasses: Beyond “Black Glass”
UV protection is a lifeline: The primary standard for a qualified pair of sunglasses is 100% blocking of UVA and UVB ultraviolet rays (labeled as UV400 or 100% UV Protection). This is not determined by the darkness of the lens tint, but by the lens material or special coating. Dark lenses lacking this function cause pupil dilation, allowing more harmful light to enter the retina, resulting in greater damage.
Lens technology determines professional scenarios:
Polarized lenses: Their core function is to eliminate glare reflected from horizontal surfaces such as water, snow, and roads. It utilizes a built-in louvered light filter layer, allowing only light from specific directions to pass through, greatly improving visual clarity, contrast, and comfort, making it an essential choice for driving, water sports, skiing, and outdoor fishing.
Photochromic lenses: The photosensitive molecules within the lenses automatically adjust their color intensity according to the intensity of ultraviolet radiation in the environment, achieving seamless switching between “one pair of glasses for multiple lighting environments,” ideal for urban life with frequent transitions between indoor and outdoor environments.
Lens colors have functional biases: Gray tones evenly reduce the intensity of various colors of light, preserving the true colors of objects; brown/brown tones enhance contrast, providing better visibility in foggy or cloudy weather; green tones are soothing, suitable for those with easily fatigued eyes; while yellow/amber tones enhance brightness in dim environments but are not suitable for prolonged use in direct sunlight.
II. Analysis of Mainstream Frame Materials: Personality Determines Choice
Frame materials directly affect wearing experience, durability, and design style:
Acetate (Acetate): The king of the fashion world. Derived from natural wood pulp and manufactured through a lamination process, it boasts unparalleled color and texture expression (such as tortoiseshell and marble patterns). It has a rich, warm texture and a high-end luster, suitable for creating retro, artistic, or statement-oriented fashion styles. Its weaknesses are its relative weight and sensitivity to humid and hot environments.
TR90 (Plastic Titanium): A symbol of sportiness and comfort. An ultra-lightweight polymer material, approximately 30% lighter than sheet metal, and possessing the flexibility of “memory metal,” it is impact-resistant and not easily deformed. It is suitable for sporty, minimalist, or styles requiring prolonged wear, aiming for a “feel-free” wearing experience.
Metals (Stainless Steel/Titanium): Symbols of classic elegance. Stainless steel is sturdy and cost-effective; pure titanium or β-titanium are high-end choices, characterized by extreme lightness, corrosion resistance, and hypoallergenic properties, allowing for extremely fine and delicate designs, suitable for business, retro, or technological styles.
Composite Materials: A fusion of intelligence. The most common design features a acetate front frame and metal temples, combining the aesthetics of acetate with the lightweight sturdiness of metal. This is the mainstream choice in the mid-to-high-end market, achieving a golden balance between aesthetics and function.
III. Four Key Considerations for Branded Custom Sunglasses
Successfully creating a sunglasses collection requires systematic strategic planning:
**Precise Positioning and Market Insight:** Clearly define your brand’s target audience (fashionistas, outdoor enthusiasts, high-end business professionals?). This determines the design style, material selection, and functional configuration (e.g., whether polarized lenses are standard).
**Building a Clear Product Line:** A healthy collection should include “leading models,” “image models,” and “profit-generating models.” For example, use small batches of classic styles to quickly test the market, use uniquely designed custom models to establish brand image, and use highly functional models to generate core profits.
**Supply Chain Agility and Depth:** Partners should be able to flexibly support small-batch, multi-batch spot purchasing to reduce trial-and-error risks, while possessing stable delivery capabilities for large-volume, high-quality customization. Professional control is required over different processes such as acetate dyeing, metal processing, and TR90 injection molding.
** Shaping a Complete Brand Experience: Product value is reflected in every detail. Collaborating with manufacturers to achieve intricate logo engraving on the inside of the temples; investing in designing branded packaging consistent with the product’s tone (such as custom eyeglass cases, carrying bags, and microfiber cleaning cloths) greatly enhances the unboxing experience, brand premium, and customer loyalty.
