1.67 Blue Block TI-Purple Coating Single-Vision Finished Lens

1. Optical Performance & Material Advantages    
High Refractive Index for Lightweight & Slim Experience: Compared with 1.61 refractive index lenses, 1.61 refractive index lenses reduce edge thickness by 15%-20% and weight by approximately 10% at the same diopter. For example, for an 800-degree myopia, when matched with a large-frame eyeglass frame, the edge thickness of the lens can be controlled within 8mm. This solves the problem of "bottle-bottom" thick lenses for people with high myopia, ensuring lighter and more comfortable wearing.

2. Core Functions of TI-purple Titanium Ion Purple Coating    
Titanium Ion Strengthening Technology: Nano-scale titanium ion particles are integrated into the coating layer, increasing the surface hardness to 8H (compared with 6H for ordinary green coatings). It is not easy to scratch due to daily friction, and its service life is extended by more than 30%. The stability of titanium ions can also resist chemical corrosion from sweat, cosmetics, etc., making it suitable for people with oily skin or those who wear makeup.    

Dual-Effect Protection Mechanism:    
Blue Light Filtration: The cerium ion component in the purple coating selectively absorbs high-energy blue light while retaining beneficial blue light (455-490nm), avoiding color distortion that may affect visual judgment (such as identifying traffic lights while driving).    
Anti-Reflection Optimization: Based on the principle of optical interference, the purple coating focuses on reducing the reflected light of 550nm wavelength from electronic screens. This minimizes glare when using mobile phones or computers at night and alleviates eye fatigue.    
Unique Appearance Design: The edge of the lens shows a light purple luster, which is different from the cool tone of traditional green coatings. When matched with metal eyeglass frames, it presents a more fashionable texture, meeting the demand of young people for the decorative effect of eyeglasses.    

3. Suitable Scenarios & Crowds    
Heavy Digital Device Users: Office workers, programmers, and students who use electronic devices for more than 4 hours a day. It can effectively relieve eye fatigue symptoms such as dry eyes and soreness, and long-term wearing can reduce the risk of retinal light damage.    
People with High Myopia: For those with myopia of over 600 degrees, while obtaining thin and lightweight lenses, it also combines blue light protection and aesthetics, eliminating the need for additional blue light-blocking clip-on lenses.    
Dual Use for Outdoor & Indoor: Full-band UV protection makes it suitable for commuting and outdoor activities. There is no need to change lenses when returning indoors, and the low-reflection feature of the purple coating ensures clearer vision in lit environments.    
Fashion-Conscious Consumers: Users who pursue both functionality and appearance. The light purple coating adds a personalized touch to the eyeglasses, making them suitable for various styles such as business and casual.
