1. Advantages: Yue Ming PMC super-bright lenses are highly purified by KR resin, and the light transmittance can reach 98.6%, and the vision is clear and true. KR super-tough material has a network cross-linked molecular structure, which is made by patented technology. The lens is not easy to break and is safer. Yue Ming PMC super bright lens can withstand the impact of small steel balls 5.6 times the national standard. 90g steel ball falls1.27m, the lens is not easy to break, and the impact resistance is excellent. Compared with the common 18-layer coated Shi Tian A6 film, Yue Ming's 20-layer coated Shi Tian A6 film completely upgraded the lens. In addition to wear resistance, antistatic, anti-reflection, anti-ultraviolet and waterproof, it also adds "easy cleaning" and "anti-oil stain", which makes it difficult to leave fingerprints.
2. Disadvantages: Yue Ming PMC ultra-bright lenses are high-quality lens materials, and the manufacturing cost is relatively high, so the price of Yue Ming PMC ultra-bright lenses is relatively high, which will make some consumers flinch. Yue Ming PMC ultra-bright lens needs regular cleaning and maintenance to keep its best optical performance and service life. If you don't pay attention to maintenance, it will affect its light transmittance and use effect.
