HMC Technology
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 they can reduce screen or strong light reflection, improving 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.
