Features

 Semi Finished Lens:

 

The starting point for freeform production is a semi-finished lens, also known as a puck due to its resemblance to an ice hockey puck. These are produced in a casting process that is also used to manufacture stock lenses. The semi-finished lenses are produced in a casting process. Here, liquid monomers are first poured into moulds. Various substances are added to the monomers, e.g. initiators and UV absorbers. The initiator triggers a chemical reaction that leads to hardening or "curing" of the lens, while the UV absorber increases the UV absorption of the lenses and prevents yellowing.

 

CR39 Features:

 

1 ) . The better among other index lenses in hardness and toughness , high impact resistance .

 

2 ) . The more easily tinted than other index lenses.


3 ) . The higher transmittance as compared with other index lenses .


4 ) . The higher ABBE value providing the most comfortable visual experience .

 

5 ) . The more reliable and consistent lens product physically and optically .

 

6 ) . The more popular in the middle level countries .
