Resin is a kind of hydrocarbon (hydrocarbon) secretion from plants, especially coniferous plants,

and is valued due to other special chemical structures. Resins can be divided into natural resins

and synthetic resins, and resin lenses are lenses that are chemically synthesized using resin

as raw materials and processed and polished. The resin lens has obvious advantages, its weight

is lighter, and it is more comfortable to wear; secondly, the resin lens has strong impact resistance,

not fragile and safer; at the same time, the resin lens also has good light transmission;

in addition, the resin lens is easy to reprocess to meet special needs Finally, coupled with

the innovation and improvement of the coating process, the resin lens also has good

abrasion resistance, so it has become the mainstream of the lens on the market.
