HMC
HMC refers to a coating technology for lenses.
In the field of lenses, HMC coating technology can improve the hardness and wear resistance of lenses.
Make the lens have basic waterproof and oil proof functions.
This coating technology makes the lenses easier to clean and maintain in daily use.
Water and oil stains are not easy to adhere to the surface of the lens, and can be easily cleaned with a light wipe.
However, it should be noted that although HMC coated lenses have certain waterproof properties, they are not specifically designed for waterproofing.
If higher levels of waterproofing or other special features are required (such as blue light protection, UV protection, etc.), other lens types may need to be selected.
Blue Coating Lenses
The main characteristics of blue coating lenses include:
Anti blue light function: It can effectively filter out harmful blue light with wavelengths between 400-440 nanometers. Helps reduce eye fatigue and protect the retina. This has a significant eye protection effect for people who use electronic devices for a long time, such as computer workers, mobile phone users, etc.
Anti radiation performance: It has the function of preventing electromagnetic wave radiation from computers, televisions, and mobile phones, providing more comprehensive protection for the eyes.
Wear resistance: Blue coating lenses perform better in terms of wear resistance, maintaining clarity and comfort for a longer period of time.
Transmittance: Although the transmittance of blue coating lenses (96.8%) is slightly lower than that of green coating lenses (98.6%), it can still meet daily wearing needs.
In addition, blue coating lenses are also suitable for night drivers, people who need to stare at screens for a long time, etc. Because it can reduce screen or strong light reflection, improve visual contrast and clarity.
Overall, blue coating lenses have become the choice of many people due to their unique anti blue light and anti radiation functions, as well as good wear resistance.
When choosing lenses, it is recommended to choose the appropriate type based on one's own needs and habits.
Frequently Asked Questions
What are the primary benefits of Anti Blue Light Lenses?
Anti blue light lenses are designed to block and filter out harmful blue light, specifically targeting wavelengths between 400-440 nanometers. This helps reduce digital eye strain, prevents fatigue, protects the retina, and provides anti-radiation defense when using electronic screens.
What lens indexes and materials are available?
Our lenses come in three refractive index options: 1.553, 1.597, and 1.667. They are manufactured using high-quality materials including Resin, Acrylic, MR-7, and MR-8 to suit different prescription strengths and frame types.
What is HMC and how does it improve the lenses?
HMC stands for Hard Multi-Coated. This technology enhances the lens surface by improving hardness and wear resistance. It also provides basic water and oil resistance, making the lenses significantly easier to clean and maintain during everyday use.
Are HMC lenses completely waterproof?
Although HMC coated lenses possess water-resistant and oil-resistant properties that allow easy cleaning, they are not designed as specialized waterproof lenses. If you require higher water resistance or specific features like UV or blue light protection, alternative specialized lenses should be selected.
How does the light transmittance of Blue Coating Lenses compare to Green Coating Lenses?
Blue coating lenses have a light transmittance of approximately 96.8%, which is slightly lower than the 98.6% transmittance of green coating lenses. Despite this minor difference, blue coating lenses fully satisfy all standard daily visual requirements while adding essential blue light filtration.
Who should choose Blue Coating Lenses?
Blue coating lenses are highly recommended for professionals who work long hours in front of computers, heavy mobile phone users, night drivers, and anyone looking to reduce glare, improve contrast, and protect their eyes from electromagnetic radiation.
