ULTRA-HARD COATING

In the field of Optical Lenses, the quality of the coating technology directly determines the quality of the wearing experience.

Today, ultra-hard coating is highly favored by the market for its excellent comprehensive protective performance and stable optical performance.

Ultra-hard coating is a high-performance, multi-layered composite functional coating. Through advanced vacuum coating technology, multiple functional layers such as hardening coating, anti-reflective coating, and anti-oil coating are precisely superimposed on the lens surface to form an indestructible "invisible shield".

One of its most prominent features is that ultra-hard coating has excellent wear resistance.The Bayer coefficient is a key indicator for measuring the scratch resistance of eyeglass lenses. The higher the value, the more scratch-resistant the lens is and the longer its lifespan.The Bayer coefficient of ultra-hard coating is as high as 10, while that of ordinary Resin Lenses is only about 4. This means that even after long-term use, the surface of ultra-hard coating lenses can still remain clean and new, and will not suffer from reduced light transmittance or blurred vision due to scratches.

Ultra-hard coating also have the advantages of being hydrophobic and oleophobic.To prove this point, the following two tests were conducted:①A waterproof test was conducted using 502 glue, and it can be seen that there is no glue residue on the lens surface, indicating a very good waterproof effect.②An oil stain repellency test was conducted using chili oil, and it can be seen that the chili oil leaves no residue, demonstrating excellent oil stain repellency.These advantages make it easier to clean the lenses, making daily maintenance much easier.

Ultra-hard coating contains a special coating called lux gold coating, which combines optical performance with luxurious aesthetics, showcasing a unique lens charm.

The most obvious feature of lux gold coating is their dazzling golden luster. Whether under lamplight or sunlight, they present a calm and gentle temperament. For wearers who value aesthetics and fashion, ultra-hard lux gold coating truly make glasses the finishing touch to facial makeup and overall look.

Every excellent coating has its own area of expertise.Ultra-hard coating is suitable for everyday scenarios that truly test the durability limits of lenses.For technicians working in precision instrument workshops, athletes cycling long distances outdoors, and safety officers inspecting construction sites, ordinary lenses are easily damaged in such unfriendly environments where sweat and dust mix. Therefore, ultra-hard coating becomes the most practical and suitable recommendation.

As mentioned above, ultra-hard coating also has hydrophobic and oleophobic properties, making it a very useful helper for people who are frequently exposed to oil and moisture.We know that once oil gets on glasses, it is very difficult to clean. It tends to make the glasses look worse and eventually leaves a greasy film that drastically reduces light transmittance.When the lenses are covered by moisture and fog, the fog won't disappear quickly. If you need to do something quickly, you can't see clearly even if you take off your glasses, and when you put them back on, it's all foggy again.However, if you use ultra-hard coating, you will feel more relaxed and at ease.

The reason ultra-hard coating stands out among numerous lens coatings lies in its consistent focus on solving real-life problems. Choose ultra-hard coating for a clear, comfortable, and worry-free visual experience.
