Semi Finished Lenses

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.

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.

Lens material

W6[9GA[4}8E{JRUJC(31GHE

CONVOX Lenses uses polymer structural resin as the lens material to improve the quality of the lens, making the lens lighter, more impact-resistant, and more translucent, ensuring that the lens is clear, bright, and durable.

*Under the same power, the lens with the higher refractive index is lighter and thinner, and it is more comfortable to wear.

New anti-reflective coating

1655965019011

The new anti-reflective film layer has super anti-ultraviolet function, and can filter a large amount of stray light, enhance the imaging quality of the lens, and the imaging effect at night is better, which greatly improves the safety of night driving.

Scratches on lenses are distracting, unsightly and in certain conditions even potentially dangerous.
They can also interfere with the desired performance of your lenses. Scratch-resistant treatments toughen up the lenses making them more durable.
