HMC (Hard Multi-Coated) refers to an advanced coating technology for optical lenses. In the field of lenses, HMC coating technology significantly improves lens hardness and wear resistance while providing essential waterproof and oil-proof properties.
This protective layer prevents water and oil stains from easily adhering to the surface, allowing lenses to be cleaned effortlessly with a gentle wipe for easy daily maintenance.
Anti Blue Light Function: Effectively filters out harmful high-energy blue light in the 400–440 nm wavelength range. This reduces visual fatigue and protects the retina, delivering notable eye comfort for heavy electronic screen users like office workers and smartphone users.
Anti-Radiation Performance: Blocks electromagnetic wave radiation emitted by computers, televisions, and mobile devices, ensuring comprehensive daily protection.
Wear Resistance: Blue coating lenses exhibit superior surface durability and wear resistance, maintaining clear, comfortable vision over long periods.
Transmittance: Although the light transmittance of blue coating lenses (96.8%) is slightly lower than green coating lenses (98.6%), it easily satisfies everyday clarity and visual demands.
Ideal Applications: Highly recommended for screen workers and night drivers, as it reduces glare and reflection from intense lighting, enhancing visual contrast and clarity.
They effectively block and filter harmful blue light in the 400-440nm wavelength range, minimizing digital eye strain, improving visual contrast, and protecting the retina during prolonged device usage.
The lenses are available in refractive index options of 1.553, 1.597, and 1.667, accommodating a wide range of vision correction prescriptions.
HMC (Hard Multi-Coated) technology enhances surface hardness, increases scratch and wear resistance, and repels water and oil stains for effortless day-to-day cleaning.
Blue coating lenses provide a light transmittance rate of 96.8%, providing optimal clarity and visual comfort for both screen work and everyday activities.
Yes, blue coating lenses help reduce harsh reflections and glare from headlights and street lighting, thereby improving nighttime contrast and visual comfort.
These optical lenses are manufactured using premium optical grade materials including Resin, Acrylic, MR-7, and MR-8 to ensure optical precision and durability.
