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 is HMC lens coating technology?
HMC refers to a coating technology for lenses that improves their hardness and wear resistance. It also provides basic waterproof and oil-proof properties, making the lenses easier to clean and maintain during daily use.
Are HMC coated lenses completely waterproof?
Although HMC coated lenses have certain waterproof and oil-proof properties that make them easy to clean, they are not specifically designed for high-level waterproofing. If you require advanced waterproof performance, other specialized lens types should be selected.
How do blue coating lenses protect the eyes?
Blue coating lenses protect the eyes by filtering out harmful blue light wavelengths between 400-440 nanometers, which helps reduce eye fatigue and protects the retina. They also prevent electromagnetic wave radiation from devices like computers, televisions, and mobile phones.
What is the light transmittance of blue coating lenses?
The light transmittance of blue coating lenses is 96.8%. While this is slightly lower than the 98.6% transmittance of green coating lenses, it is still highly efficient and fully satisfies daily visual and wearing requirements.
Who should choose blue coating lenses?
Blue coating lenses are highly recommended for individuals who spend long hours looking at digital screens (such as computer workers and mobile phone users) and night drivers, as these lenses reduce reflections and improve visual contrast and clarity.
