This study developed a precise hybrid optical lens (PHOL) that included polymer and glass materials.
Although glass offers superior anti-thermal, anti-environmental, anti-scraped corrosion resistance and optical properties than polymer materials, it is difficult to fabricate glass materials.
The PHOL can be used to reduce aberration errors in optical systems using two materials.

Moreover, this process also exhibit the defects and tolerence limitations of the implants and not suitable for the high melting point materials.
This will provide an excellent basis for discussing the choice of manufacturing process, material to be used and the adaptability of the process and materials to the mass production.
