--Good glasses, good vision.

The refractive index of a lens is an important parameter of the lens, usually with numbers such as 1.49, 1.56, 1.61, 1.67, etc. These numbers represent the optical refractive index of the lens, whi...

Polarized lenses are lenses that only allow light in a specific polarization direction from natural light to pass through. Due to its filtering effect, wearing it will make things appear darker. In...

Resin lenses are lenses made of organic materials. Internally, it is a polymer chain like structure that is connected to form a three-dimensional network structure. The intermolecular structure is ...

The main raw material for glass lenses is optical glass. Excellent optical properties, not easily scratched, high refractive index. Glass lenses have good light transmittance and mechanical and che...
