Description

Technical Field

[0002] Coated glass lenses refer to glass products that have one or more layers of thin films coated on the surface of ordinary glass lenses through a specific process. These films are usually composed of one or more inorganic or organic substances, with the purpose of changing the optical properties of the glass or enhancing its functional characteristics. They can reduce surface reflections, improve transmittance and visual clarity. They are widely used in camera lenses, eyeglass lenses and optical instruments.
