With the widespread use of electronic devices, people’s eyesight has been deteriorating. Myopia affects increasingly younger children, and presbyopia now occurs at an earlier age. Various eye conditions have also become more prevalent, leading to a sharp rise in the number of people wearing glasses.
Common lens coatings include green coating, gold coating, magenta coating, blue coating and yellow-green coating. Blue coatings deliver excellent radiation resistance and wear resistance, yet their light transmittance is lower than that of green coatings. Green coatings feature superior light transmittance but are less wear-resistant than blue ones. Radiation-proof lenses are covered with a blue anti-radiation coating. When you tilt and rotate such lenses, a distinct blue iridescent glow can be seen on the surface.
Hard Coating
Silicon dioxide hardening technology is applied to the lens surface, bringing its wear resistance close to that of glass lenses.
Anti-Fouling Coating
Mainly made of fluorides, this coating covers the porous anti-reflective layer. It reduces the contact area between the lens and water or oil, so water droplets and grease hardly stick to the surface. It is also known as a water-repellent coating.
Anti-Radiation Coating
This coating consists of metallic compounds that form a protective barrier on the lens. Following the electromagnetic interference shielding principle, a conductive film is applied via specialized coating techniques. It reflects and absorbs low-frequency radiation and microwave radiation, relieving potential eye heating caused by low-frequency radiation and preventing visual fatigue.
UV Protection Coating
It blocks harmful ultraviolet rays in sunlight.
