I. Techinical Data:

II. The definition of semi finished lens:​       

1) Semi-finished lens is the raw blank used to produce the most individualized RX lens according to thepatient's prescription. Different prescription powers request for different semi-finished lens types or base curves.

2) 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.

III. The advantages of the 1.67 Index:

1. Lighter weight and thinner thickness, up to 50% thinner and 35% lighter than other lenses

2. In the plus range, aspherical lens is up to 20% lighter and thinner than spherical lens

3. Aspheric surface design for outstanding visual quality

4. Flatter front curvature than non-aspheric or non-atoric lenses

5. Eyes are less magnified than with traditional lenses

6. High resistance to breakage (very suitable for sports and children’s spectacles)

7. Full protection against UV rays
