Introduction to glass lenses
The main raw material of glass lenses is optical glass, which has superior optical properties,
good light transmittance and mechanochemical performance, constant refractive index,
and stable physical and chemical properties. Secondly, glass lenses have a higher refractive
index and are often used for lens purposes. The highest refractive index is 1.9.
Finally, the surface of the glass lens is harder and more resistant to abrasion.
However, the weight of the glass lens is relatively large due to the material, which affects
its wearing comfort to a certain extent. In addition, the glass lens itself is fragile, especially
with the improvement of the production technology and technology of the resin lens.
In recent years, the use of glass lens Fewer and fewer.
